For those still using Visual Studio 2008 and developing using jQuery, you will no doubt desire the use of IntelliSense in your text editor to browse the jQuery objects.
To make sure you get this benefit, you must have SP1 for Visual Studio 2008 applied and run a patch which you can download here.
Download jQuery 1.4.2 and the –vsdoc.js for jQuery 1.4.1 and place them in the same folder in your web app. Rename the –vsdoc.js file to “jquery-1.4.2.min-vsdoc.js”.
Add a script tag to the top of your ASP.NET web form or master page:
You should now be able to see IntelliSense at work anywhere you reference jQuery.
