Is Window Open Already?

[marcl97]

On my parent window, I have links that open smaller pop-up windows. I want to prevent users from trying to open a pop-up that is already opened. Any way to detect if a pop-up is already open and prevent it from being opened a second, third, etc. time?

Tx.

If you assign it to a variable there will only be one nstance of it at all times, and when the user attempts to open it again, the window will be brought back to the top of the window stack (much like the focus method).<script type="text/javascript">
function pop(url)
{
window.open(url, '', 'height=300,width=300,scrollbars=1');
}
</script>Then, you could use it like this:<a href="http://www.google.com/" onclick="pop(this.href);return false;">Google.</a>Good luck.
