Intellisense support in Visual Studio 2008/2010 for jQuery closures {

Question

I'm trying to get Intellisense to correctly work for closure. As a plugin author, I always use a closure to create an isolated environment for my plugin code:

(function($) {
  // code here
})(jQuery);

But the problem here is that Intellisense doesn't pick up that jQuery is being passed in the execution of the function. Adding $ = jQuery in the above code fixes the problem, but that's just poor execution, IMHO.

Anyone here got this working without resorting to embedded ASP server tags (this is a standalone JS file)? Something preferably not including modifying existing code other than some odd /// <option .../>-like solution?

Answer 1

I dont know if you have read Roni's or Rick's articles on this - I assume you have already made intellisense work in VS?

Not being a jQuery person - having just this was nice

It isn't clear in your post or your comments, but at the top of your .js file, did you add:
/// <reference path="jquery.vsdoc.js" />
to the top of your file?

ScottGu's blog has more on intellisense in external libraries (not jQuery-specific).

Also, here's another possible solution, is this what you mentioned with $=jQuery?:

(function($) {  // private closure;  <% /*debug*/ if (false) { %> 
    $ = jQuery;
    // <% } /*end debug*/ %>
    $(function() {
        // do stuff
    });
})(jQuery);

But before installing the hotfix make sure you have SP1 installed in your system.

Answer 5

I'm surprised this doesn't work in VS2010 (I don't think you will be able to make it work in VS2008).

You could try adding an xml doc comment to the beginning closure to define the param type. Something like this:

/// <param name="$" type="Jquery" />

(I don't know what the class name for the jquery object is -- or if there is even one available).

I'm experiencing the same problem - has anyone found a solution to this?
