Call javascript function with bind

Question

I have the function:

$(this.myObject).click(A.bind(this));
function A(){
     //  stuff here
}

I want to call from within a second function (binding this).

$(this.myOtherObject).click(B.bind(this));
function B(){
      A();             //  works but does not bind
      A.bind(this);    //  does not work
}

How can I do this?

Answer 1

您想使用call(this)而不是 bind() 因为 bind() 只是返回该方法。

A.call(this)

Answer 2

function B(){
    A();             //  works but does not bind
    A.bind(this);    //  does not work
}

bind is for creating a new function bound to a context (see bind documentation ). If you go that way, you would need to call the new function :

A.bind(this)();

However, you should rather use call method or apply method which will directly call the function with a specific context :

A.call(this);
A.apply(this);
