Hi,
You can hook the 'load' event on the return value from `window.open`:
var wnd = window.open(...);
Event.observe(wnd, 'load', childLoaded);
That will only work if the window you're loading and the window
loading it are from the same origin.[1] And of course, the window.load
event happens fairly late, after all the images have been loaded.
JavaScript in your child window can call into your parent window to
tell it when it's ready. Assuming you have Prototype loading in your
*child* window, it would be something like this:
In a script tag in the child window:
document.observe("dom:loaded", phoneHome);
function phoneHome() {
if (window.opener && window.opener.readyCallback) {
window.opener.readyCallback(window);
}
}
In a script tag in the parent window:
function readyCallback(child) {
/* do something */
}
That will happen earlier than window.load (because Prototype's
dom:loaded event happens as early as possible). I'm 99% sure they
still have to be from the same origin, I don't think window.open
grants the child any special access rights to the parent. (I'm sure it
doesn't grant the parent special rights to the child.)
