JavaScript Callback function Problem

Question

Please see my code below:

        var callback = function(popup_window) {
            popup_window.close();
           //some more codes here
        };
        var prepare = function(cb) {
            popup_window = window.open("my_url");
            this.cb(popup_window);
        };
        function refresh(){
            prepare(callback);
        };

How can I pass the popup_window variable to the callback function ?

You already are passing popup_window to the callback in your code this.cb(popup_window);. What do you really mean? Note: why this.cb()? I wouldn't expect that to work, while cb() should work. — nnnnnn

I am trying to pass popup_window but this actually not passed to callback function because my window did not closed. I am trying to close the opened window. — Tareq

        var popup_window = window.open("my_url");
        cb(popup_window);
    };

Change this.cb(popup_window); to cb(popup_window);

Replace this.cb() with cb()
