JavaScript - referencing 'this' in an inner function

Question

Consider the following code:

MyClass.prototype.my_func = function () {
    this.x = 10;
    $.ajax({
        // ...
        success: function (data) {
                   


        

Answer 1

You can make usage of Function.prototype.bind for that:

MyClass.prototype.my_func = function () {
    this.x = 10;
    $.ajax({
        // ...
        success: function (data) {
            alert(this.x);
        }.bind(this);
    });
}

Now the parent context variable is also bound to the anonymous function.
