JQuery Support, IntelliSense in Visual Studio

Developers can get assistance from Microsoft’s Product Support Services group with issues related to use of the popular jQuery open source JavaScript library when used with Visual Studio, and VS 2010 simplifies jQuery development with improved IntelliSense. JQuery can reduce the amount of code required in Web pages that use JavaScript for dynamic user interface features, such as drag-and-drop and animations, which is helpful when creating Web applications that use the Asynchronous JavaScript and XML (AJAX) development pattern. JQuery joins a small set of open source development technologies that Microsoft has singled out for special support.

Simplified Development for AJAX Applications

JQuery is a small (19KB runtime) library that provides methods to select and modify Web page elements and generate animation effects (e.g., for progress indication), using a syntax that resembles that of Cascading Style Sheets, a formatting language already familiar to many Web developers. JQuery can substantially reduce the amount of code required for a task; for example, text detail on a Web page can be added or removed with a smooth transition animation using one line of jQuery code. JQuery is often used when implementing applications with AJAX, which is a technique in which JavaScript in a Web page downloads small amounts of XML data in the background so that the entire page doesn’t have to be refreshed when something changes. For example, both Google Maps and Bing Maps use AJAX technologies to allow users to scroll a map in a Web page by clicking and dragging, without a page refresh.
