Intranet Application - trying to close main window

[XgrinderX]

Hello!

I am writing an application that is going to be run on a local Intranet. I want to load the default page which is really just the application launcher. It opens a new featureless window (no menu bar, no toolbar, no address bar, etc) which contains the application. I then want to close the launcher window. But every time I do, I get the message, "The Web page you are viewing is trying to close the window".

So I added some code to the end of my launcher page that looks like this:

window.opener = self;
window.opener.close();

This works on some machines but not on others and I do not know why. Is there some way to tell IE that this is an Intranet application and that its ok for me to be able to close that window myself?

Thanks in advance for any help you can offer.

Not easily, I suspect. Is it important to close the main window? Why not have it populate with your "thanks for playing!" screen, such that when they finish playing with the extruded application and close the window, they're faced with a "thank you" window?

Cheers,


Edward

Well....the reason we want it to close is because it still has the Menu Bar and Address Bar and all that stuff displayed which gives users the opportunity to get into IE and goof things up. That's why we want that window to close itself down.

Maybe there is another way to do this?

on the main page try this.

self.opener = this
self.close()

How is that different from what I already have?

 

[mwolf00]

I'm not so sure it is much different, just thought you could try it.

I think yours is an elaborate way to say self.close() while mine is reseting the opener of the page to the page itself and then closing.

how about:

location = closePage.html

then have closePage.html's body onLoad = "window.close();"

kind of messy, but it should work

It's because some machines have a security vulnerability that allows you to set the opener property of the window to itself.

most likely the machines that are not cooperating are < IE5.5 - this only works on IE5.5+

Hmmm...that woul be weird. The ones that work are all IE6, the ones that don't work are all IE5.

Yes, that's correct.

So is this window.opener workaround the only option? seems like IE should be able to be set up so that it gives a little more control for Intranet applications.

IE usually doesn't know or care about the location of the files and as a rule, web pages that kill themselves nudge close to the sort of functionality that really belongs in the hands of the user, instead of a script.

Did

self.opener = this
self.close()

work for you?

If you really want the ultimate kind of user control over your internal net web pages -- complete control over the viewing environment and variable scope and all that exciting &quot;application&quot; style stuff -- then you build an executable VB app and stick it on your server. Send your employees the link to the executable.
