View Full Version : How to get a window reference?

02-24-2003, 04:19 PM
I have a window with links, some of these links open another window. If that window is already open, it opens that link in the same window.

The problem is, I don't want to reload this new window every time, I just would like to call a function inside it, if it is already open. To do so I need a reference to it. How can I get the reference to this window?

The opener window can be reloaded, so I can't just store it in a variable.

Hope it makes some sence...

If you are using JavaScript to open the new window like this:

Then you can reference the window using the variable NewWin. So to reference a function in that window you could try NewWin.function_name().

Thanks for answering, but I meant it slightly different...

The problem is when the opener window has been reloaded, and I'd like to call a function in the new window.

Image this scenario:

1. Load main window.

2. Click on link that opens a new window (child window).

3. Click on the same link in the main window. This time the child window is already loaded, so I just want to call a function.

4. Click on a link in the main window, that reloads itself.

5. Click on that first link in the main window again. The child window is still loaded, so I only want to call a function again.

How can I get the reference to the child window this time?

Basically you want to get access to all the desktop windows - whether the main window created it or not.

I posted this question a while back. The reply was - cannot do it in JavaScript.

well, that figures...:)

I thought there might be a way since there is a frames-collection, which is supposed to hold all window-objects created by the current document. The problem is how to reach it...

If I create the window like this:

var newWin=open("url.html","newWinName","");

..shouldn't it be possible to access a function in the new window using something like:


The name parameter seems to be different than the frame.name property, though...
