Question

In the js code specified below –

var tclass = function(){
   this.func2=function(){console.log('func2')};
   this.b={
      func1: function(){console.log('func1')}
   }
}

how do i call func2 inside func1 on the same instance?

Answer 1

You’d have to keep a reference to both this and that function in the closure.

var tclass = function(){
   var obj = this;
   function func2(){console.log('func2')};
   this.func2 = func2;
   this.b={
      func1: function(){ obj.func2(); }
   }
}

Also it’s more useful to declare functions with actual function declaration statements:

function tclass() {
  // ...
}
