The use of “this” is confusing me in JavaScript

Question

Working with the JavaScript one of the confusing thing is when using this

var x = {  
  ele : \'test\',
  init : function(){ 
    alert(this.ele)         


        

Answer 1

To me, it helped a lot the following guideline: every time you see this think owner. The object who owns the variable name to which the function is assigned will become the this. If you cannot make sense to who owns it, then this will be window.
