Can you help with my process flow please.

I was successfully using some javascript error handling to force the user to go back to the page 1 with errors and correct them. It worked a treat!
Code: 
<html>
<script type="text/javascript">
{
	alert("<% Response.write "Please correct your: " &emsg  %>")
	history.back();
}
</script>
</html>

The above code is on Page2 and handles the errors. I recently introduced in the hyperlink on Page 1 a Target=_blank as opposed to _Self as I wanted to create separate windows.

Now of course the error handling will not work as there is no history to go back to

How can I selectively force a user to go to Page 1 when there is an error detedcted.

Many thanks

Short answer: You can't.

Long answer: Depending on how you opened the new window you could target its parent and focus it, however the window.focus doesn't work well across browsers for different reasons. Firefox for instance can block any attempt to manipulate its windows so the focus() call does not work.

You're best bet would be to alert, and then close the window. In most cases this will return the user to the original page.
