Jquery: how to check if a newly opened window has been fully loaded? / window loads an external page (like www.yahoo.com)
the following doesn't work , why ?
var myWindow=null;
myWindow = window.open(开发者_StackOverflow中文版targetUrlVar,"_blank","resizable=yes");
$(myWindow).load(function(){
alert('hello');
});
Though MyWindow is a Window reference, no check is performed to see whether or not it has been fully loaded. i thought $(window).load(...) would work here for "window " being replaced by "MyWindow".
the following works:
$(myWindow).load(function(){
alert('hello');
});
for targetUrlVar being an internal resource (like a page belonging to my domain) it works..
but as soon as i wanted to used the .load() or myWindow.onload() with a targetUrlVar being an external page (such as www.yahoo.com or www.google.com ), it doesn't work any more...
No alert is displayed..
i need you help... thank you everyone
If you want to trigger the alert when the child window is open regardless of the state of the child window's DOM then this should work. I also provided a way to test this assumption.
Create a test PHP script (or similar scripting language) with the following content:
<html>
<head><title>test</title></head>
<body>
<?php sleep(5); // Sleep to delay DOM from loading ?>
Done sleeping...
</body>
</html>
Then call this test page as your child window usingthe following javascript:
win = window.open('test.php', 'test', 'width=300, height=400, x=800');
win.focus();
$(win.document).ready(function() {
alert('Window is open');
});
You'll notice that the alert() from the parent window fires before you see "Done sleeping..." appear in the child window.
$(document).ready(function() {
//perform tasks, DOM is loaded
});
Hope this helps.
I see this question is somewhat old.
However, arthur stated,

I think that the issue may be due to the targetUrlVar being external; the alert may be blocked to prevent cross-site scripting (aka XSS).
