For example, the below JavaScript uses jQuery to find all <div> elements within a page that have a CSS class of “product”, and then animate them to slowly disappear:

$("div.product").slideUp('slow').addClass("removed");

As another example, the JavaScript below uses jQuery to find a specific <table> on the page with an id of “datagrid1″, then retrieves every other <tr> row within the datagrid, and sets those <tr> elements to have a CSS class of “even” – which could be used to alternate the background color of each row:

$("#datagrid1 tr:nth-child(even)").addClass("even");

The jQuery library also works well on the same page with ASP.NET AJAX and the ASP.NET AJAX Control Toolkit.

Visual Studio figures out external script references, such as to JQuery, by following special reference comments it finds at the top of .js files:

/// <reference path="jquery-1.2.3.js" />

You can download the JQuery from here. You can get more details on JQuery from http://jquery.com/ .

For intellisense support for JQuery you need to install this Hotfix.

Comment for javascript is written inside for intellisense support. JavaScript has the interesting feature that calling toString on a function returns the code of this function including the comments and thus the doc comments. Here’s a similar example in JavaScript where the documentation is written inside of a class constructor:

Another difference with C# or VB.NET is that property and event accessors are two different entities in JavaScript. For this reason, to choose where the documentation should be for those members. Properties should be documented in the getter and events in the “adder” for this reason:

document.getElementById(div_id).style.JS_property_reference = “new_CSS_property_value”;

As this is the need in most of the web application and web pages, and almost everyone does that with images. We can still create the rounded corner div with using images and just by CSS alone.

Here are few links that I digged and are helpful you to attain this,
