Question

I have javascript like this:

function Cat() { 

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

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

}

var TopCat = new Cat();

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

Answer 1

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(); } 
    });    
}
