onunload not working in Chrome and safari
Question
I have parent page and child page. In child page body tag i have below code.
<body onunload="window.g_autoclosed=true;if(window.opener&&window.opener.NavModelessClose){window.opener.NavModelessClose(window,false);}">
when i click on button in parent page, child page should close and call the onunload event.
The unload event is raising correctly in IE and FF. But it is not raising in chrome and safari.
Please help me.

Modern WebKit browsers don't necessarily fire the unload event at the moment where the page is hidden. This is done in order to allow improved caching.
You might consider replacing the use of unload with the pagehide event.

Unload works in modern browsers, but for example you cant launch an alert. See: http://bugs.jquery.com/ticket/10509
Also if you want to use $.get or $.post in unload, is better that you use $.ajax with async=false.
Ex:
$(window).unload(function() {
$.ajax({
url: '/some_url.htm',
async: false
});
});

也许尝试onbeforeunload事件？

是的，附加到窗口（或子页面的内部窗口）的onbeforeunload应该这样做
