window.opener alternatives

Question

I am opening a modal popup window. Then I access a parent window textbox and other attributes using window.opener. It is working fine in firefox but not in IE8.

Answer 1

As a cross-browser alternative, you can give a custom attribute to the new window while you are opening it:

var popup = window.open(...);
popup.isPopup = true;

Then, in the referred page:

if (window.isPopup) {
  // Do something
}
else {
  // Not in a popup
}
