javascript popup window remember last size and position

I am opening pop-up window through JavaScript with resize option for end user. End user may resize pop-up window or change its default position by dragging it.

I have requirement of remembering last position and size of pop-up window when user closes the window.

At present I can keep last size of the pop-up window in onbeforeunload event using cookie. But still could not find last position of the window.

Am I missing something very obvious, or what I am doing is the correct开发者_Python百科 way to do it.

The function window.open() returns a handler to the opened window.

var myWindow = window.open('some_url','some_name');

You could maybe then use the myWindow to obtain its position.

Make a try with window.screenLeft/window.screenTop on IE and window.screenX/window.screenY in other browsers to get the positon.

Hope this helps, d.

Finally I used cookie solution to remember position of last open window.
