Opening and closing a window

How do I center a popup window for all resolutions by adrikev
Posted: 7 Aug 02 (Edited 28 Feb 03)

As you already know, everyone has a different graphics resolution on their PC. So how do you center a pop-up window for all resolutions. It is easier than you think.

Lets say you want to open a window that has a size of 200h x 150w. By taking half of the height and width (100 and 75 respectively) you can pinpoint the center of the window. Then with a little math you can center the window. Here is how it is done

function MyPopUpWin() {
var iMyWidth;
var iMyHeight;
//half the screen width minus half the new window width (plus 5 pixel borders).
iMyWidth = (window.screen.width/2) - (75 + 10);
//half the screen height minus half the new window height (plus title and status bars).
iMyHeight = (window.screen.height/2) - (100 + 50);
//Open the window.
var win2 = window.open("filename.htm","Window2","status=no,height=200,width=150,resizable=yes,left=" + iMyWidth + ",top=" + iMyHeight + ",screenX=" + iMyWidth + ",screenY=" + iMyHeight + ",toolbar=no,menubar=no,scrollbars=no,location=no,directories=no");

To call this function in HTML use this:

<A HREF="javascript:MyPopUpWin()">This is the link</a>

It's that simple.
