Question

I have a requirement that I need to create a link to open a form in a new window and then when I click the same link it will focus on the existing window again.

this works well with the following code

<input type="button" value="Click" onclick = "return OpenWindow();"/>

<script>
var win = null;
function OpenWindow()
{
   if (win == null || win.closed)
   {
      win = window.open('http://localhost/Conditions.aspx', 'Condition');
   }
   win.focus();
   return false;
}
</script>

However, I experienced a problem, when I switch to different page and come back to the page which has the link. the variable win will not retain the previous reference.
If I click the link again, it will refresh the existing window (which is not what I want!) and then focus on it.

Is there any way that I can keep variable reference? or does anyone know how to solve this problem?

I had the same issue and was resolved on Window.open only if the window is not open

If you basically want the window focused instead of refreshed when the link is clicked, even if the parent window has been closed, re-opened, or changed, this will do the trick.

I was about to resort to using cookies.
