Opener

darkhalf · November 18th, 2005, 10:52 AM

Hi,

I have 2 frames (top,bottom).. The bottom frame executes the OpenWin() function which opens a new window... Now when I try to close it using 'document.bottom.opener.close();' it doesn't work. The error that it gives me is 'document.bottom.opener' is null or not an object. Am I misusing opener? Also, before someone mentions it, I can't add a variable for the window.open (ie newwin = window.open)...

function OpenWin()
{
window.open("","HSEUsage","scrollbars=yes,resizabl e=yes,menubar=no,toolbar=no");
}

opener refers to the document that opened the window, not the window that was opened.

So you want something like this:

Code:

var $HSEUsage;

function OpenWin()
{
    $HSEUsage = window.open("","HSEUsage","scrollbars=yes,resizable=yes,menubar=no,toolbar=no");
}

function CloseWin()
{
    $HSEUsage.close();
}

HTH!

Regards,
Rich

As I said, I can't declare a variable for the new window... and since I was off base with the opener function, how does one read what's on thew new window??

Er? You haven't presented a case for why you can't declare a variable. How about enlightening us a little more about your thought process and what you expect to achieve.

You either declare a variable for the window, or close the window from within it.

> how does one read what's on thew new window

Via the variable you assign the object resulting from the window.open handler for the new window, there's no other method AFAIK to access a subordinate window.

The reason that I can't declare a variable for the window is that I don't control the content of that page. I'm loading a page through an iframe, once this page is loaded I simulate the click on a button, sadly instead of just changing the page to the new content, they open a new window. Now what I'm trying to do, is get data from the popup, then close it when done.

Then it appears you're trying to do cross-domain scripting. It can't be done.

Imagine a phishing website that loads a bank website in a frame, then in the evil frameset, a javascript records every keystroke and sends them back to evil webmaster's server via XMLHttpRequest. Whaalah, now some doophus has some poor sap's bank username and password.

Well, that's not my intentions whatsoever... But it's nice to know that it can't be done... Thank you.

I wasn't implying that it was, just trying to convey the reason why it isn't possible. ;)

You'd have better luck manipulating content from other sources on the server-side, BTW, before it even gets to the client.
