Popup window not opening on IE7

Question

Hi Javascript gurus, I have this Javascript code which is working fine on Firefox , but it is not working on IE 7. Any ideas why?

Here is the code

function TestWindow()
{
     SimpleWindow('Default.aspx', 'Simple Test', 200, 200, 'yes')
}

function SimpleWindow(mypage,myname,w,h,scroll)
{

    var win= null;

    var winl = (screen.width-w)/2;


    var wint = (screen.height-h)/2;

    settings='height='+h+',width='+w+',top='+wint+',left='+winl+',scrollbars='+scroll+',toolbar=no,location=no,status=no,menubar=no,resizable=no,dependent=no'

    win=window.open(mypage,myname,settings)

    if(parseInt(navigator.appVersion) >= 4)
        {
            win.window.focus();
        }
    }

Answer 1

For myname parameter use only a-zA-Z0-9 characters. IE doesn't like any other, especially whitespace characters.

Answer 2

Check popup blockers

Answer 3

You may have realized that IE is giving the error "Invalid argument."

IE doesn't seem to like window names with spaces in them. Change 'Simple Test' to 'SimpleTest' etc.

Answer 4

Check for reserved words. Your parameter name "scroll" is probably messing up your code in IE.
