Scripting question for brainiacs

[2MuchMark]

Is there a way to refresh a parent page from a pop-up?

For example,

Imagine you have a page with a link that says "click here to sign up". When clicked a pop-up opens requesting the usual info. Once completed, the user can close that window and cause the previous or parent window to automatically refresh.

Suggestions?

The only thing I can think of is to do it using http push or comet.
- Source page that spawns popup has jquery requesting blah.php every second waiting for a value of "true"
- Source page loads popup
- Popup shows whatever, onUnload it runs a script to set blah.php to true
- Source page get's it's true signal and does whatever

Can be made more "live" using http push but that's the idea basically here.

I think you can do this with native javascript and the window object and using window.opener to control the window which triggered the popup

Parent page:

<script type="text/javascript">
    function OpenPopup() {
        window.open('ChildPopupWindows.aspx', '', 'width=200,height=100');            
    };
</script>

<input type="button" value="Open popup" onclick="javascript: return OpenPopup()" />

Child Page:

<script type="text/javascript">
    function CloseWindow() {
        window.close();
        window.opener.location.reload();
    }
</script>

<asp:Button ID="btnServer" runat="server" OnClick="btnServer_Click" Text="Request server" />
    <br />        
    <input type="button" value="Close Window" onclick="javascript: return CloseWindow();" />

C#:

protected void btnServer_Click(object sender, EventArgs e)
    {

    }

Or something like this in the child page using window.opener:

<script>
    window.onunload = refreshParent;
    function refreshParent() {
        window.opener.location.reload();
    }
</script>
