Window status works in FF, but not IE...why?

msprothero · March 22nd, 2005, 09:32 AM

I have a project where I need to check to see if a pop-up window I've created is still open. I've pieced together some code, but it only works correctly in FF, but not IE. JavaScript is not my forte and I'm at a loss as to what the issue is.

The code below works fine as is, but if I change this line:
      <a href="#" onclick="winOpen('','testSite','295','300','no');r eturn false;">Open</a><br>

to this:

      <a href="#" onclick="winOpen('http://www.msn.com','testSite','295','300','no');return false;">Open</a><br>

it doesn't work in IE...it comes back saying the window doesn't exist even if it does.

Any ideas?

Thanks!
Chris

You need to store the child window in a global variable:

Code:

var oChild = null;
function winOpen(Url)
{
  return window.open(Url); //Add extra parameters if needed
}

function checkWindow(Window)
{
  return (Window && !Window.closed);
}

function closeWindow(Window)
{
  if (checkWindow(Window))
  {
    Window.close();
  }
}

Then in your code:
oChild = winOpen(...);

Later

closeWindow(oChild);

As a side issue NEVER use eval, you don't need it and it's a terrible resource hog. e.g.
eval("window.testSite.document") just needs to be =>
window.testSite.document
