I am developing an intranet application, in which, in some pages, when the user selects an option, I am using a pop-up window to retrieve the data and displaying it in the main page. The pop-up opens, fetches data, puts in main page and closes itself.

Since the user is not interacting with the pop-up, I would prefer it to be hidden. Can this be done ? I checked a Javascript book, which says the 'alwaysLowered' property can be used to send the pop-up behind other windows but this is a security feature and available only for signed scripts.

My Questions are:
1. Can the pop-up be hidden ?
2. What is a signed script ?

It depends on the way your creating the window. I'm sure there are many ways to do it. If I remeber correctly you can do it via this method:

var win = new PopupWindow();
 
win.showPopup();
 
win.setUrl("http://www.site.com");
 
win.hidePopup();

Hope this helps you.

Sorry, it's not working. I am getting the error
"PopupWindow is undefined"

Here's the code (with what I was using earlier)

var newWindow ;
var v_Options;
var v_Bars;
v_Bars = 'directories=no, location=no, menubar=no, status=no,titlebar=no,toolbar=no';
v_Options = 'scrollbars=yes,resizable=no,Height=10,Width=10,left=100,top=100,visible=false,alwaysLowered=yes';
//newWindow = window.open("Popdata.htm",'PrintWin',v_Bars + ',' + v_Options);
newWindow = new PopUpWindow() ;
newWindow.showPopup();
newWindow.setURL("Popdata.htm");
newWindow.hidePopup();

Actually, opening a hidden window is on the list of operations forbidden for security reasons.

But there is nothing to prevent you from putting it under something. It still shows on the taskbar.

"Putting it under something" = Putting it behind another window ? That's fine with me. But how do I do that ? By setting the z-order of the window ? If it shows in the taskbar, it's acceptable.

I had a similar objective, and achieved it with an I frame
In the HTML :
<iframe id="Download_Frame" style="display:none; visibility:hidden;">
JunkMessage
</iframe>

In the Javascript :
MyIFrame = document.getElementById("Download_Frame");
MyIFrame.src = "MyUrl.php?params=" + Parameters;

It worked fine for me.

As far as I know, IFrame is supported only by IE. Unfortunately I need it to be cross browser compatible. Is IFrame supported by all major browsers like Firefix, Opera, etc ?

I used it for Firefox, IE and Opera (didn't test any others)
