I want to run the following code but only if the document has not been closed.

parent.opener.document.forms[0].submit();

(if its not open the code crashes)


thanks

sorry but it didn't work..

      if(parent.opener){
            alert(1234);
            parent.opener.document.forms[0].submit();
      }


I get the alert come up although the opener is not there any more.

in your parent window declare a variable like this :
var myvar = true

in your popup window
<html>
<head>
<script language="javascript">
<!--
function checkparent() {
    if (opener.myvar) alert("yes")
    else alert("no")
}
//-->
</script>
</head>
<body>
<form>
 <input type="button" value="Valid" onclick="checkparent">
</form>
</body>
</html>
