jQuery: receive document ready() on child window

问题

I'm trying to get notified when the child window I'm opening has its document loaded and ready. This doesn't seem to work:

win = window.open(href, 'test', 'width=300, height=400');
win.focus();
$(win.document).ready(function() {
           // Ok, the function will reach here but if I try to manipulate the
           // DOM it doesn't work unless I use breakpoints
           $(this).contents().find("...").doStuff(); // nothing happens
    });

What do I have to do?

回答1:

Have you tried this? —

$(win.document).ready(function() {
    $(win.document).contents().find("...").doStuff();
});

This question discusses something very similar. Duplicate?

回答2:

I had a similar problem and for me the .load event on the window did work, the .ready did not. So you may try:

win = window.open(href, 'test', 'width=300, height=400');
$(win).load(function() {
    $(this).contents().find("...").doStuff(); 
});

Use window.opener in script on site, which you are loading and execute function defined in global (!) at first page.

Main page:

<html>
<head>
<script type="text/javascript">
    window.notify = function () {
        alert('runned from opened window');
    };
    window.onload = function() {
        document.getElementById('button').addEventListener('click', function() {
            window.open('test.html');
        }, false);
    };
</script>
</head>
<body>
<button id="button">Open window</button>
</body>

Opened page:

<html>
<head>
<script type="text/javascript">
    window.onload = function() {
        window.opener.notify()
    };
</script>
</head>
<body>
    Popup site
</body>
</html>

Simply add this code in iframe,

$(document,parent.document).ready(function(){
alert('Done');
});
