This question has already been answered:

var obj = { name: 'cc', trade: function() { console.log(this.name); //cc } }; obj.trade(); var obj = { name: 'cc', trade: function() { console.log(this); //name, trade (function() { console.log(this); //window, в этом и вопрос, почему, //ведь эта функция выполняется внутри метода объекта })(); } }; obj.trade();

Why does this function, which is inside the trade method of obj , equal to window , and not obj ?

Because what matters is not where the function is located, but how it is called:

 (function() { console.log(this); }).call(this);
