Javascript,calling child window function from opener doesn't work

rated 0 times [ 73] [ 6] / answers: 1 / hits: 21928 / 15 Years ago, fri, january 22, 2010, 12:00:00

I'm developing a web application that opens a popup using windows.open(..). I need to call a function on the opened window using the handle returned by window.open, but I'm always getting the error message addWindow.getMaskElements is not a function, as if it couldn't access the function declared on child window. This is the behavior in both IE and FF. My code looks like this:

function AddEmail(target,category)

{

    if(addWindow == null)

    {

        currentCategory = category;

        var left = getDialogPos(400,220)[0];

        var top =  getDialogPos(400,220)[1];

        addWindow = window.open(adicionar_email.htm,null,height=220px, width=400px, status=no, resizable=no);

        addWindow.moveTo(left,top);

        addWindow.getMaskElements ();

    }

}

I've googled and read from different reliable sources and apparently this is supposed to work, however it doesn't.
One more thing, the functions in child window are declared in a separate .js file that is included in the adicionar_email.htm file. Does this make a difference? It shouldn't..
So, if anyone has ran into a similar problem, or has any idea of what I'm doing wrong, please, reply to this message.
Thanks in advance.

The window creation is not a blocking operation; the script continues to execute while that window is opening and loading the HTML & javascript and parsing it.

If you were to add a link on your original page like this:

<a href=# onclick=addWindow.getMaskElements();>Test</a>

You'd see it works. (I tried it just to be sure.)

**EDIT **

Someone else posted a workaround by calling an onload in the target document, here's another approach:

function AddEmail()

{



        if(addWindow == null) {

        addWindow = window.open(test2.html,null,height=220px, width=400px, status=no, resizable=no);

        }



        if(!addWindow.myRemoteFunction) {

            setTimeout(AddEmail,1000);

        } else { addWindow.myRemoteFunction(); }

}

This keeps trying to call addWindow.myRemoteFunction every 1 second til it manages to sucessfully call it.
