Is there a way for a JQuery ajax success function to access the object it's contained in?

I have javascript like this:

function Cat() { 

  this.meow = function() { // meow };

  $.ajax( do AJAX call, success: this.meow(); );

}

var TopCat = n开发者_开发问答ew Cat();

This does not work because 'this' makes no sense in the context of the success function. Is there an elegant solution?

You're looking for the context parameter to the ajax method.
It allows you to set the context in which all callbacks will be called.

function Cat() { 
    this.meow = function() { // meow };
    $.ajax({
        context: this, 
        success: function() { this.meow(); } 
    });    
}
