Recently I was having problem to open pop up window in IE browsers. Although it works properly in all other browsers.

In IE , window is open on self window rather than another window.

Finally I found the error in my code, and that was window name problem.

I defined the window name with space (window name). It must be without space (window_name).

Syntax must be

window.open(url,'window_name','height=570,width=400,scrollbars=1');
