Basic Javascript Question

[Mark Fox]

Hello,

I am attempting to do something very simple. I have
a page MainPage.aspx and a popup window Popup.aspx. When
users click on the linkbutton in the popup window I am
looking to do some server side processing in Popup.aspx,
then have the popup window close, and have the
MainPage.aspx do a postback to the server. But I am
having trouble determining what client side javascript
Popup.aspx should render after it does its server side
processing. Are there any samples or articles tha
demonstrate how to do this? I keep getting "Object
Expected" in CloseChildWindo w():

script.js
-------------------------------
var PopUp;

// Called from MainPage.aspx
function OpenPopup(id, mode, eid)
{
var url = "";
url += "Controls/PopUp.aspx?";
url += "FormName=" + document.forms[0].name;
url += "&id="+ id;
url += "&m=" + mode;
url += "&eid="+ eid;

var width = 250;
var height = 150;

var str = "";
str += "toolbars=n o,";
str += "status=no, ";
str += "resizable= 0,";
str += "scrollbars=0," ;
str += "width=" + width + ",";
str += "height=" + height + ",";

if ( window.screen ) {
var ah = screen.availHei ght - 30;
var aw = screen.availWid th - 10;

var xc = ( aw - width ) / 2;
var yc = ( ah - height ) / 2;

str += ",left=" + xc + ",screenX=" + xc;
str += ",top=" + yc + ",screenY=" + yc;
}

PopUp = window.open( url, 'EmailList', str );
}

function CloseChildWindo w(id, postBack)
{
debugger;
PopUp.close();
if (postBack)
__doPostBack(id ,'');
}

The code I have in Popup.aspx is

<script language="JavaS cript">
<!--

window.onload=w indow_onload();

function window_onload() {
window.opener.C loseChildWindow ('a', true);
}

//-->
</script>

Any help would be appreciated! Thanks.

Re: Basic Javascript Question

Hi, besides from all the obvious things like domain rights, and case
sensitiv try to look for this:

For JavaScript to be public(seen by other programs) in IE, It has to be
declared in the html header.

Re: Basic Javascript Question

If I interpret your JavaScript correctly, it looks like your script is
supposed to close the window AFTER a PostBack. The page in the browser after
a postback is not the same page that was in the browser BEFORE the PostBack.
It may be the same HTML document, but the memory of the new instance is not
the same as the memory of the old - HTTP is stateless. To the browser, it is
a whole new page. Therefore, there is no longer a window object reference in
memory pointing to the child window. Using the same variable name does
nothing.

Re: Basic Javascript Question

Hi

If I get you right...

Do the processing in the popup
Return a script to the popup that calls some method(s) in the opener

window.opener.d ocument.forms[0].mySubmitBtn.cl ick(); // This will click a
submit button named mySubmitBtn
Or call a function in parent window(opener)
window.opener.F UNCTIONNAME();
window.close();// Close child

Re: Basic Javascript Question

Mark,

I have some code for just this at my website, www.aboutfortunate.com. Just
search the code library for: "refresh main window" or something similar. The
title of the sample you want is:

Close a popup window and refresh the parent window

I downloaded the code from your site (which is very

Hi Mark,

When you use the JavaScript window.open() method, the window object that
refers to the child window is in the parent window's HTML document. If the
parent window posts back, the reference is lost, as the parent window's
document is unloaded. If the child window posts back, the document in the
child window changes, and all memory in that document is lost, but as the
reference to the child window is in the parent window's document, it isn't
lost.

The child window can close itself without any problems.

Re: Basic Javascript Question

Mark,

The Javascript button you clicked on is not the actual code library. That
was a link to the javascript project I've built which contains javascripts I
use over and over. All the other javascripts and other code I haven't made
into classes is in the datagrid on the main code library page.

When you click the "code library" link on the site in the main area of the
page is a datagrid. Above the datagrid is a search text box and button. Do
your search there. Or page through the datagrid.

Sincerely,

Re: Basic Javascript Question

Kevin,

Thank you for your clear explanation! Based on
that, I was able to get it working with the child window
closing itself. Thanks a million.
