Question

I have the following code:

///<reference path="../typescript/jquery.d.ts" />

function addThemePrototypes() {
    var templateSetup = new Array();
    $.fn.addTemplateSetup = function(func, prioritary)
    {
        if (prioritary)
        {
            templateSetup.unshift(func);
        }
        else
        {
            templateSetup.push(func);
        }
    };
}

When I try to add the following:

  $('a').addTemplateSetup(

Into this same file I notice there is no intellisense and typescript does not seem to know about the addTemplateSetup prototype that I just added.

Is this the correct way for it to work or do I always need to add things like the definition for addTemplateSetup to an JQueryStatic definition file and then include that?

Answer 1

You will need to declare it in some way to make Typescript not complain, the easiest is to declare it as any:

interface JQuery {
    addTemplateSetup: any;
}

But to get best intellisense support add info about the parameter types aswell:

interface JQuery {
    addTemplateSetup: (func: Function, priority: bool) =>void;
}
