Center Popups
Much abused but not always bad.
Popup windows are not used much anymore, because most people block them. However, they are still handy in some cases, and if used should always be centered. Few things are more irritating than popups that open crammed in the corner. The following is a commonly-used script for automatic popup centering.
<script type="text/javascript">
function popup(mylink, windowname)
{
if (! window.focus)return true;
var wLeft = (screen.width - 640) / 2;
var wTop = (screen.height - 480) / 2;
var href;
if (typeof(mylink) == 'string')
href=mylink;
else
href=mylink.href;
window.open(href, windowname, 'width=640,height=480,left=' + wLeft + ',top=' + wTop + ',resizable=yes,scrollbars=yes');
return false;
}
</script>
Change the desired size in both places, then call it with something like this:
<input type=button value="My Pop" onclick="popup('http://some.com/some.html','My Pop')">
Temporarily allow pops and .
There are many other free popup scripts on the web. I like this one because it’s simple and just right for most purposes.
