How to bind "this" for jQuery callbacks?

Question

I am trying to set up a callback in jQuery that correctly binds "this" to the calling object. Specifically, here is the code I am working with. I am doing an ajax call in a Object like this:

Object.prototype.doAjaxCall = function(url)
    {
        $.get(url, null, this.handleAjaxResponse );
    }

However, in Object.prototype.doAjaxCall, this does not refer to the correct thing. I have worked with Prototype before and I know you need to bind this when you do the Ajax call, but I can't seem the find the correct way to do that in jQuery. Can someone point me in the right direction?

Answer 1

Use the jQuery ajax context property to bind this. eg:

$.ajax({
    context: this,
    url: url,
    type: 'GET'
}).done( function(data, textStatus, jqXHR) {
    this.handleAjaxResponse();
});
