ok heres what you do:
create a function say winOpen(); the all you have to do is somewhere above where you declare the winOpen() function you just create a set of string variables with the proporties that change and create an array or list of these different properties and the function would go something like this:
<script language="Javascript">
//list your different windows here, one URL and one name for each,
var windowOneURL = "
http://www.anandtech.com";
var windowOnename = "windowOne";
var windowOneSize = '"width=500","height=400"';
//heres the function
function winOpen(URL,name,size) {
//proporties that don't change between windows - what ever you need here
var staticOptions = '"scrollbars=no","resizeable=no"';
var finalOptions = staticOptions + ',' + size;
//open up the window with all of its proporties
var newWin = open(URL,name,finalOptions);
}
</script>
and all you have to do is just call it like this winOpen(windowOneURL,windowOnename,windowOneSize)
hope this helps you, I tried it out and I got it to work, if you have anyquestions feel free to ICQ me, and I will also check back here.
