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.
