Understanding the visibility scope in JavaScript's object-oriented programming

I have the following code snippet:

function A() {
    this.AFunction = function() {
        var b = new B();
        b.BFunction();
    }
}

function B() {
    this.BFunction = function() {
         // some code
         $.ajax({ url: url
             success: BSuccess,
             // and so on
         })
    }

    this.BSuccess = function() {
         // some code
         this.anotherBFunc();
    }

    this.anotherBFunc = function() {
         // some code
    }
}

a = new A();
a.AFunction();

However, when I try to call anotherBFunc, it fails. Can anyone help me understand why this is happening?

Answer №1

If you want to keep the scope, one option is to utilize jQuery's proxy

success: $.proxy(this.BSuccess,this),

Alternatively, for more modern browsers, you can also use bind

success: this.BSuccess.bind(this),
