View Full Version : Child and Parent windows

08-01-2002, 04:48 PM
I have a HTML file in a window (Window1) containing a textbox and a button.
The button opens a sized window (Window2) which the user can use to browse to whichever page they want anywhere on the internet.
When they close Window2 I want the last url they visited (i.e. the current url of Window2) to populate the text box on my original page (Window1) .
Can this be done?

Could you give me any pointers?

I would really appreciate any help you could give me.

That cannot be done due to the same-origin security policy. You are only allowed to read the URL of files that reside in your domain, everything else is considered an infringe on privacy.

mordred is correct there, but.... if you were tracking on an intranet you could get the location of the child window by polling it.

Try this, it was a proof of concept. Note that it will only show URLS that are on the same server. It updates every second, and has a counter in it, the thought was to time how long the user was at a particular page. It never got off the ground as we convinced them it was not a good idea to spy so blatantly :)

<form name=temp method="post" action="http://www.xmission.com/~tnelson/mirror.php" onSubmit="return validateForm(this)">
<a href="javascript:showSecondWindow()">New Window</a><br>
<input type="text" name="URL" size="50" value=""><br>

<script language="JavaScript">
function showSecondWindow(){

myCount = 0;
function checkPage(){
document.temp.URL.value = myCount + "URL: " + Swin.location;
