View Full Version : math variable not working

07-02-2003, 09:54 PM
here's the function I call to pop up a window
and center in depending on the monitor resolution.

function doIt() {
var centerW=((screen.width - 800) / 2);
var centerH=((screen.height - 600) / 2);
window.open('main.htm','EgrArt', 'height=600,width=800,location=no,left=centerW,top=centerH,scrollbars=no,resizable=no,menubar=no');

centerW and centerH give the right numbers when I alert them, but they don't work within the window.open and I don't know why.

Any help would be greatly appreciated

You have to break from the string and concatenate so that their values are used

window.open('main.htm','EgrArt', 'height=600,width=800,left=' + centerW + ',top=' + centerH );

Also, so you know, any window property defaults to false, so you don't need to set all of them to 0. Just leave them out and they won't show up.
