Question

I am passing in a jQuery object into a function from another file via an array like the following:

$(document).bind("loadStoreDisplayCallGoals", function(source, urlParams)
{
    var selectedStoreDocument = urlParams["storeDocument"];
}

selectedStoreDocument should be a jQuery object, however Visual Studio Intellisense will never recognize it as such. I tried adding extending selectedStoreDocument with $.extend:

// cast selectedStoreDocument to a jQuery type
$.extend(selectedStoreDocument, $);

However, extending selectedStoreDocument wiped out all of my jQuery methods (.each, .find, etc.).

How can I get selectedStoreDocument to appear as a jQuery object in IntelliSense? Note that I am working in Visual Studio 2010.

Answer 1

I created a separate file for utility functions, and a second file for the utility functions + VSDoc.

utilities.js:

function castToJQuery(item)
{
    return item;
}

utilities-vsdoc.js:

function castToJQuery(item)
{
    /// <summary>
    ///     1: $(item) - "Casts" the specified item to a jQuery object for the sake of Intellisense
    /// </summary>
    /// <returns type="jQuery" />
    return $("dummy");
}

Now I can call castToJQuery in any of my downstream files to make Visual Studio think a dynamic property is a jQuery object.

var selectedStoreDocument = castToJQuery(urlParams["storeDocument"]);
selectedStoreDocument.find("products");

Visual Studio now works with Intellisense for my dynamic urlParams[“storeDocument”].
