jQuery video tutorial 10 - jQuery CSS Method
 
11:07
jQuery video tutorial 10 - jQuery CSS Method jQuery CSS() Method: The jQuery CSS() method is used to set one or more CSS style(s) to the selected HTML element(s). It is also used to get the value of a CSS style applied to the selected HTML element(s). Setting the single CSS style or property: Syntax: $(selector).css(“css-property”,”value”); It helps us to select any html element(s) targeted by the given selector and apply the given CSS property. Ex: $(“#firstp”).css(“background-color”,”red”); It selects any html element(s) whose id attribute value is set to firstp and applies the CSS property background color to red . Setting multiple CSS styles or properties: Syntax: $(selector).css({“css-property1”:”value1”,” css-property2”:”value2”,….}); It helps us to select any html element(s) targeted by the given selector and apply the given set of CSS properties. Ex: $(“#firstp”).css({“background-color”:”green”,”color”:”white”}); It selects any html element(s) whose id attribute value is set to firstp and applies the CSS properties background color green and text color white . Getting the value of a single CSS style or property: Syntax: $(selector).css(“css property”); It helps us to select any html element(s) targeted by the given selector and return the value of a given CSS property. Ex: alert($(“#firstp”).css(“background-color”)); It selects any html element(s) whose id attribute value is set to firstp and returns the value of background-color CSS property. The current implementation of the CSS() method in jQuery allows us to set multiple CSS properties to the selected HTML element(s), but only allows us to get one CSS property at a time. ========================================= Follow the link for next video: jQuery video tutorial 11 - jQuery selectors https://youtu.be/HpRdrhCq158 Follow the link for previous video: jQuery video tutorial 09 - jQuery syntax https://youtu.be/UvMuWgBzIHc =========================================
jQuery add event handler to dynamically created element

Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/04/jquery-add-event-handler-to-dynamically.html In this video we will discuss, how to add event handlers to dynamically created elements. Let us understand this with an example. The following example, allows us to dynamically create new list item (li), attach a click event handler and add it to the unordered list (ul). This happens when you click "Add a New List Item" button. The problem with this approach is that we are binding a click event handler to every list item. This means if you have 500 list items, then there will be 500 event handlers in the memory and this may negatively affect the performance of your application. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('li').on('click', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { var newListItem = $('<li>New List Item</li>').on('click', function () { $(this).fadeOut(500); }); $('ul').append(newListItem); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html> A better way of doing the same from a performance standpoint is shown below. In this example, the click event handler is attached to the listitem (li) parent element (ul). Even if you have 500 list items, there is only one click event handler in memory. So how does this work 1. When you click on a list item (li), the event gets bubbled up to its parent (ul) as the list item (li) does not have an event handler 2. The bubbled event is handled by the the parent (ul) element, as it has a click event handler. 3. When a new list item is added dynamicaly, you don't have to add the click event handler to it. Since the newly created list item (li) is added to the same parent element (ul), the click event of this list item also gets bubbled upto the same parent and will be handled by it. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('ul').on('click', 'li', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { $('ul').append('<li>New List Item</li>'); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html>

jQuery #id selector

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/jquery-id-selector.html In this video we will discuss 1. What are jQuery selectors 2. Different selectors in jQuery 3. #id selector in jquery What are jQuery selectors One of the most important concept in jQuery is selectors. jQuery selectors allow you to select and manipulate HTML elements. Different selectors in jQuery jQuery selectors allow you to select html elements in the DOM by 1. Element ID 2. Element Tag Name 3. Element Class Name 4. Element attribute 5. Element Attribute values and many more Id selector in jquery To find an HTML element by ID, use the jQuery #id selector Example : The following example finds button with ID button1 and attaches the click event handler. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').click(function () { alert('jQuery Tuorial'); }); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] Changes the background colour of the button to yellow $(document).ready(function () { $('#button1').css('background-color', 'yellow'); }); Important points to remember about jQuery #id selector 1. jQuery #id selector uses the JavaScript document.getElementById() function 2. jQuery #id selector is the most efficient among all jQuery selectors. If you know the id of an element that you want to find, then always use the #id selector. 3. HTML element IDs must be unique on the page. jQuery #id selector returns only the first element, if you have 2 or more elements with the same ID. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').css('background-Color', 'yellow'); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [input id="button1" type="button" value="Click Button" /] [/body] [/html] 4. JavaScript's document.getElementById() function throws an error if the element with the given id is not found, where as jQuery #id selector will not throw an error. To check if an element is returned by the #id selector use length property. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { if ($('#button1').length ] 0) { alert('Element found') } else { alert('Element not found') } }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] 5. JavaScript's document.getElementById() and jQuery(#id) selector are not the same. document.getElementById() returns a raw DOM object where as jQuery('#id') selector returns a jQuery object that wraps the DOM object and provides jQuery methods. This is the reason you are able to call jQuery methods like css(), click() on the object returned by jQuery. To get the underlying DOM object from a jQuery object write $('#id')[0] 6. document.getElementById() is faster than jQuery('#id') selector. Use document.getElementById() over jQuery('#id') selector unless you need the extra functionality provided by the jQuery object.

HTML: HTML is the standard markup language for creating Web pages. HTML stands for Hyper Text Markup Language HTML describes the structure of Web pages using markup HTML elements are the building blocks of HTML pages HTML elements are represented by tags HTML tags label pieces of content such as "heading", "paragraph", "table", and so on Browsers do not display the HTML tags but use them to render the content of the page. CSS: Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS describes how elements should be rendered on screen, on paper, in speech, or on other media. JQuery: jQuery is a JavaScript library designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax. It is free, open-source software using the permissive MIT License. Web analysis indicates that it is the most widely deployed JavaScript library by a large margin. ENJOY!!!!!!!!!!!!!!!!!!!!!!!!!

To select the elements by tag name use jQuery Element Selector Syntax : $(element) $('td') // Selects all td elements $('div a') // Select all anchor elements that are descendants of div element $('div, span, a') // Selects all div, span and anchor elements Alerts the total count of td elements on the page [script type="text/javascript"] $(document).ready(function () { alert($('td').length); }); [/script] Selects all the tr elements on the page and changes their background colour to red [script type="text/javascript"] $(document).ready(function () { $('tr').css('background-Color', 'red'); }); [/script] Alerts the HTML content of the table [script type="text/javascript"] $(document).ready(function () { alert($('table').html()); }); [/script] Alerts the HTML content of each table row [script type="text/javascript"] $(document).ready(function () { $('table tr').each(function () { alert($(this).html()); }); }); [/script] Select and changes the background colour of all the div, span and anchor elements [script type="text/javascript"] $(document).ready(function () { $('div, span, a').css('background-Color', 'yellow'); }); [/script] Select all anchor elements that are descendants of div element [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('div a').css('background-Color', 'yellow'); }); [/script] [/head] [body] [div] [a href="http://pragimtech.com"]PragimTech[/a] [/div] [br /] [a href="http://microsoft.com"]Microsoft[/a] [/body] [/html] Changes the background color of even rows to gray and odd rows to yellow in both the tables. [script type="text/javascript"] $(document).ready(function () { $('tr:even').css('background-Color', 'gray'); $('tr:odd').css('background-Color', 'yellow'); }); [/script] To change the background color of even rows to gray and odd rows to yellow just for one of the table, use #id selector along with element selector. [script type="text/javascript"] $(document).ready(function () { $('#table1 tr:even').css('background-Color', 'gray'); $('#table1 tr:odd').css('background-Color', 'yellow'); }); [/script]

The only difference is in the syntax. With append method we first specify the target elements and then the content that we want to append, where as we do the opposite with appendTo method. jquery prepend example : The following example prepends the specified HTML to all div elements <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('div').prepend('<b>Tutorial </b>'); }); </script> </head> <body style="font-family:Arial"> <div id="div1">jQuery</div> <div id="div2">C#</div> <div id="div3">ASP.NET</div> </body> </html> jquery prependTo example : The above example can be rewritten using prependTo as shown below. $('<b>Tutorial </b>').prependTo('div'); What is the difference between prepend and prependTo Both these methods perform the same task. The only difference is in the syntax. With prepend method we first specify the target elements and then the content that we want to prepend, where as we do the opposite with prependTo method. jQuery append existing element example : These methods (append, appendTo, prepend, prependTo) can also select an element on the page and insert it into another <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('div').append($('#mySpan')); }); </script> </head> <body style="font-family:Arial"> <span id="mySpan"> Programming</span> <div id="div1">jQuery</div> <div id="div2">C#</div> <div id="div3">ASP.NET</div> </body> </html> Difference between prepend and append prepend method, inserts the specified content to the beginning of each element in the set of matched elements, where as append method inserts the specified content to the end of each element in the set of matched elements.

How to set multiple attribute values using jQuery attr() method 5. How to remove an attribute using jQuery removeAttr() method What are jQuery DOM manipulation methods jQuery DOM manipulation methods manipulate the DOM in some manner. The complete list of jQuery DOM manipulation methods can be found at the following link. http://api.jquery.com/category/manipulation/ jQuery attr method is used to set or retrieve attribute values of html elements. Retrieves the title attribute value of the first matching element $('div').attr('title') Example : In this example we have 2 DIV elements. Since attr() function retrieves only the attribute value of first matching element, we only get the title attribute value of the first DIV element. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { alert($('div').attr('title')); }); </script> </head> <body style="font-family:Arial"> <div id="div1" title="My DIV1"> DIV 1 </div> <div id="div2" title="My DIV2"> DIV 2 </div> </body> </html> To retrieve the title attribute value of all the matching elements, jQuery each() method can be used. <script type="text/javascript"> $(document).ready(function () { $('div').each(function () { alert($(this).attr('title')); }); }); </script> Sets the title attribute value of all the matching elements to "new div title" $('div').attr('title', 'new div title'); Example : If you want to set the same value for the title attribute of all the elements, then there is no need to loop thru each element. All the div elements in this case will have 'new div title' as the title attribute value. <script type="text/javascript"> $(document).ready(function () { // set the same title attribute value for all the DIV elements $('div').attr('title', 'new div title'); // Retrieve and alert the title attribute value of all DIV elements $('div').each(function () { alert($(this).attr('title')); }); }); </script> If you want to set a different value for the title attribute, then you may need to loop thru each element. <script type="text/javascript"> $(document).ready(function () { // sets a different title attribute value for each DIV element $('div').each(function (i) { $(this).attr('title', 'div ' + (i + 1) + ' title'); }); // Retrieve and alert the title attribute value of all DIV elements $('div').each(function () { alert($(this).attr('title')); }); }); </script> How to set multiple attribute values : Using a JSON object to set multiple attribute values <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { var config = { 'title': 'New Div Title', 'style': 'border:3px solid red;', 'name': 'My Div' }; $('div').attr(config); var result = ''; $('div').each(function () { result += 'title = ' + $(this).attr('title') + '<br/>'; result += 'style = ' + $(this).attr('style') + '<br/>'; result += 'name = ' + $(this).attr('name') + '<br/><br/>'; }); $('#resultSpan').html(result); }); </script> </head> <body style="font-family:Arial"> <div id="div1" title="My DIV1"> DIV 1 </div> <br /> <div id="div2" title="My DIV2"> DIV 2 </div> <br /> <span id="resultSpan"> </span> </body> </html> Instead of creating a separate JSON object (config) and then passing it to attr() method, you can create the JSON object inline. $('div').attr({ 'title': 'New Div Title', 'style': 'border:3px solid red;', 'name': 'My Div' });

Notice div1 has 2 classes - small and big. [html] [head] [title][/title] [script src="Scripts/jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('.small').css('border', '5px solid red'); }); [/script] [/head] [body] [div class="small big"] DIV 1 [/div] [br /] [div class="small"] DIV 2 [/div] [/body] [/html] Selects all elements that has both the classes - small and big. There should be no space between the class names. [script type="text/javascript"] $(document).ready(function () { $('.small.big').css('border', '5px solid red'); }); [/script] If you have a space between the two class names then we are trying to find descendants, i.e. find elements with class big that are descendants of an element with class small. [html] [head] [title][/title] [script src="Scripts/jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('.small .big').css('border', '5px solid red'); }); [/script] [/head] [body] [div class="small big"] DIV 1 [/div] [br /] [div class="small"] DIV 2 [div class="big"] DIV 3 [/div] [/div] [/body] [/html] Another way to selects all elements that has both the classes - small and big is by using filter method. But this approach is slower because it will first create a list of objects with class "small" and then removes elements that does not have class "big" [script type="text/javascript"] $(document).ready(function () { $('.small').filter('.big').css('border', '5px solid red'); }); [/script]

How to add Smooth Scrolling to your one page website with jQuery
 
19:50
Smooth scrolling not only looks cool but, for one-page sites, it can also help make for a better user experience. In this video, I take a look at how you can add smooth scrolling to your site with just a few lines of jQuery. Not only do I look at smooth scrolling though, but the demo site I'm using it based on Bootstrap, which has a nice 'active' link class which highlights one of the links in the navigation. I look at how, with a few more lines of jQuery, we can have that active link class switch between links in the navigation as we scroll down the page, once again helping with the user experience! And sure, you could find some scripts out there that do it for you, but being able to write your own jQuery can be really useful. You're writing the exact code that you need in your one case and not something which is bloated and heavy for no reason. My goal with this video isn't just for you to be able to copy my code, but to understand a bit more of how jQuery is working and to be able to write a bit of your own scripts going forward. Find the codepen here: http://codepen.io/kevinpowell/pen/dWzGox -- I'm on some other places on the internet too!

This widget is in interactions category on the jQuery UI website. http://jqueryui.com/draggable/ Consider the following HTML <div id="draggableDiv" class="divClass"> Drag me around </div> .divClass { height: 200px; width: 200px; background-color: red; color: white; display:table-cell; vertical-align:middle; text-align:center; } To make the above div element draggable $('#draggableDiv').draggable(); Some of the useful options to customize the draggable widget axis - Constrains dragging to either x or y axis containment - Constrains dragging to within the bounds of the specified element or region cursor - The CSS style of the cursor during the drag operation opacity - opacity during the drag operation revert - Boolean property that specifies if the element should revert to its start position when dragging stops revertDuration - The duration of the revert animation, in milliseconds snap - Specifies whether the element being dragged should snap to other elements. Value can be boolean or a selector. When set to true, the element will snap to all other draggable elements. When a selector is specified the element being dragged will snap to the element specified by the selector snapTolerance - The distance in pixels between the element being dragged and the element to which to snap to, at which snapping should occur. cancel - Prevents dragging from starting on specified elements Constrains dragging to x axis $('#draggableDiv').draggable({ axis : 'x' }); Constrains dragging to within the bounds of the parent element HTML <div id="containerDiv" style="height:300px; width:300px; border:3px solid black"> <div id="draggableDiv" class="divClass"> Drag me around </div> </div> jQuery $('#draggableDiv').draggable({ containment : 'parent' }); Changes the cursor style to "move" during the drag operation $('#draggableDiv').draggable({ cursor: 'move' }); Changes the opacity to 0.3 during the drag operation $('#draggableDiv').draggable({ opacity : '0.3' }); Reverts the div element to its start position when dragging stops. Revert animation completes in 1000 milli-seconds. $('#draggableDiv').draggable({ revert: true, revertDuration : 1000 }); The following example 1. Snaps the coloured div elements to the div element with thick black border. 2. The snapping occurs as soon as the distance between any of the coloured div element and the div element with thick black border is 50 pixels 3. The cancel option cancels dragging from starting on the div element with thick black border HTML <div id="redDiv" class="divClass" style="background-color: red"> Red Div </div> <div id="greeDiv" class="divClass" style="background-color: green"> Green Div </div> <div id="blueDiv" class="divClass" style="background-color: blue"> Blue Div </div> <div id="brownDiv" class="divClass" style="background-color: brown"> Brown Div </div> <br /> <br /> <div id="snapDiv" style="height: 400px; width: 400px; border: 5px solid black"> </div> Style .divClass { height: 200px; width: 200px; color: white; display: table-cell; vertical-align: middle; text-align: center; } jQuery $('div').draggable({ snap: '#snapDiv', snapTolerance: 50, cancel : '#snapDiv' });

With the basic jQuery functionality, animate() method cannot animate non-numeric style properties like color, background-color, and border-color. jQuery UI adds the ability to animate color properties. In the example below a reference to jQuery UI is included, hence the color animations work. If we remove the reference, color animations will not work, but other numeric style properties (font-size, border-width) continue to work. <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script src="jquery-1.11.2.js"></script> <script src="jquery-ui.js"></script> <script type="text/javascript"> $(document).ready(function () { var toggleColor = false; $('#btnAnimate').click(function () { var divElement = $('#myDiv'); if (toggleColor) { divElement.animate({ 'font-size': '15', 'border-width': '1', 'background-color': 'red', 'color': 'white', 'border-color': 'green' }, 2000); } else { divElement.animate({ 'font-size': '20', 'border-width': '10', 'background-color': 'green', 'color': 'white', 'border-color': 'red' }, 2000); } toggleColor = !toggleColor; }); }); </script> <style> </style> </head> <body style="font-family: Arial"> <form id="form1" runat="server"> <div id="myDiv" style="width: 500px; border: 1px solid black; padding: 5px; font-size: 15px"> At Pragim Technologies, training is delivered by real time software experts having more than 10 years of experience.

Determinate progress bar - Use when the actual status can be accurately calculated 2. Indeterminate progress bar - Use to provide user feedback when the actual status cannot be calculated To get a determinate progress bar, set the value option of the progressbar() function to an integer value between 0 and the max. $('#progressbar').progressbar({ value : 65 }); To get an indeterminate progress bar, set the value option of the progressbar() function to false (boolean) $('#progressbar').progressbar({ value : false }); Get value for jQuery progressbar from a select element HTML Select Percentage : <select id="ddlPercentage"> <option value="10">10</option> <option value="20">20</option> <option value="30">30</option> <option value="40">40</option> <option value="50">50</option> <option value="60">60</option> <option value="70">70</option> <option value="80">80</option> <option value="90">90</option> <option value="100">100</option> </select> <input type="button" id="btn" value="Set Value" /> <br /><br /> <div id="progressbar"></div> jQuery $(document).ready(function () { var progressbarDiv = $('#progressbar'); progressbarDiv.progressbar(); $('#btn').click(function () { progressbarDiv.progressbar({ value: parseInt($('#ddlPercentage').val()) }); }); }); Display jQuery progress bar value HTML Select Percentage : <select id="ddlPercentage"> <option value="10">10</option> <option value="20">20</option> <option value="30">30</option> <option value="40">40</option> <option value="50">50</option> <option value="60">60</option> <option value="70">70</option> <option value="80">80</option> <option value="90">90</option> <option value="100">100</option> </select> <input type="button" id="btn" value="Set Value" /> <br /> <br /> <div id="progressbar" style="position:relative"> <span style="position:absolute; left:50%; top:20%" id="progressBar-label"> </span> </div> jQuery $(document).ready(function () { var progressbarDiv = $('#progressbar'); progressbarDiv.progressbar(); $('#btn').click(function () { progressbarDiv.progressbar({ value: parseInt($('#ddlPercentage').val()), change: function () { $('#progressBar-label').text(progressbarDiv.progressbar('value') + '%'); } }); }); });

The :checked selector selects all checked checkboxes or radio buttons. Let us understand this with an example. Selects all checked radio button elements $('input[type="radio"]:checked') Example : When you click the submit button without selecting any radio button, "No radio button checked" message should be displayed. When you click the submit button after a radio button is checked, then a message stating "Male is checked" or "Female is checked" should be displayed. Replace < with LESSTHAN symbol and > with GREATERTHAN symbol. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnSubmit').click(function () { var result = $('input[type="radio"]:checked'); if (result.length > 0) { $('#divResult').html(result.val() + " is checked"); } else { $('#divResult').html("No radio button checked"); } }); }); </script> </head> <body style="font-family:Arial"> Gender : <input type="radio" name="gender" value="Male">Male <input type="radio" name="gender" value="Female">Female <br /><br /> <input id="btnSubmit" type="submit" value="submit" /> <br /><br /> <div id="divResult"> </div> </body> </html> Selects all checked checkbox elements $('input[type="checkbox"]:checked') Example : When you click the submit button without checking any checkbox, "No checkbox checked" message should be displayed. When you click the submit button after checking a checkbox, then a message stating the number of checkboxes checked and their values should be displayed. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnSubmit').click(function () { var result = $('input[type="checkbox"]:checked'); if (result.length > 0) { var resultString = result.length + " checkboxe(s) checked<br/>"; result.each(function () { resultString += $(this).val() + "<br/>"; }); $('#divResult').html(resultString); } else { $('#divResult').html("No checkbox checked"); } }); }); </script> </head> <body style="font-family:Arial"> Skills : <input type="checkbox" name="skills" value="JavaScript" />JavaScript <input type="checkbox" name="skills" value="jQuery" />jQuery <input type="checkbox" name="skills" value="C#" />C# <input type="checkbox" name="skills" value="VB" />VB <br /><br /> <input id="btnSubmit" type="submit" value="submit" /> <br /><br /> <div id="divResult"> </div> </body> </html>

Since these methods modify DOM, they belong to DOM manipulation category. wrap unwrap wrapAll wrapInner wrap - Wrap an HTML structure around each element in the set of matched elements. Consider the following HTML <div id="div1"> DIV 1 </div> <div id="div2"> DIV 2 </div> <div id="div3"> DIV 3 </div> The following line of code wraps each of the above div element with another div element. $('div').wrap('<div class="containerDiv"></div>'); So the HTML in the DOM would now look as shown below. To view the DOM HTML use the browser developer tools. <div class="containerDiv"> <div id="div1"> DIV 1 </div> </div> <div class="containerDiv"> <div id="div2"> DIV 2 </div> </div> <div class="containerDiv"> <div id="div3"> DIV 3 </div> </div> Example : <html> <head> <title></title> <style> .containerDiv { background-color:red; color:white; font-weight:bold; margin: 5px; } </style> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { alert($('div.containerDiv').length); $('div').wrap('<div class="containerDiv"></div>'); alert($('div.containerDiv').length); }); </script> </head> <body style="font-family:Arial"> <div id="div1"> DIV 1 </div> <div id="div2"> DIV 2 </div> <div id="div3"> DIV 3 </div> </body> </html> unwrap - Remove the parents of the set of matched elements from the DOM. Example : <html> <head> <title></title> <style> .containerDiv { background-color:red; color:white; font-weight:bold; margin: 5px; } </style> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { alert($('div.containerDiv').length); $('div').wrap('<div class="containerDiv"></div>'); alert($('div.containerDiv').length); $('div').unwrap(); alert($('div.containerDiv').length); }); </script> </head> <body style="font-family:Arial"> <div id="div1"> DIV 1 </div> <div id="div2"> DIV 2 </div> <div id="div3"> DIV 3 </div> </body> </html> wrapAll - Wrap an HTML structure around all elements in the set of matched elements. Consider the following HTML <div id="div1"> DIV 1 </div> <div id="div2"> DIV 2 </div> <div id="div3"> DIV 3 </div> The following line of code wraps all of the matching div element with another div element. $('div').wrapAll('<div class="containerDiv"></div>'); So the HTML in the DOM would now look as shown below. <div class="containerDiv"> <div id="div1"> DIV 1 </div><div id="div2"> DIV 2 </div><div id="div3"> DIV 3 </div> </div> wrapInner - Wrap an HTML structure around the content of each element in the set of matched elements. Consider the following HTML <div id="div1"> DIV 1 </div> <div id="div2"> DIV 2 </div> <div id="div3"> DIV 3 </div> The following line of code wraps each of the above div element content with another div element. $('div').wrapInner('<div class="containerDiv"></div>'); So the HTML in the DOM would now look as shown below. <div id="div1"> <div class="containerDiv"> DIV 1 </div> </div> <div id="div2"> <div class="containerDiv"> DIV 2 </div> </div> <div id="div3"> <div class="containerDiv"> DIV 3 </div> </div>
