jQuery target different window/popup

问题

I have jQuery open a popup:

function idealPopUp(str){
    var url = str;
    var windowName = "idealPopUp";
    var windowSize = 'height=820,width=784,toolbar=no,scrollbars=yes';              
    window.open(url, windowName, windowSize);
    event.preventDefault();
}

can I, from the original window, have jQuery target that popup? I want to know when it closes. The content of the popup is from another site and I have no control over it's jas/html etc.

I have this in the original window to try and talk to the popup:

$(document).ready(function(){
    $('#idealPopUp').unload( function () {
        alert("BING");
    });
});

..

..

UPDATED FUNCTION:

function idealPopUp(url){
    var windowName = "idealPopUpWindow";
    var windowSize = 'height=820,width=704,toolbar=no,scrollbars=yes';

    var idealPopUpWindow = window.open(url, windowName, windowSize);

    $(idealPopUpWindow).unload( function () {
        alert("BING");
    });
    event.preventDefault();
}

回答1:

var otherWindow = window.open(url, windowName, windowSize);

is a window reference; now you can

$(otherWindow).unload(...);
