javascript - onunload not working in Chrome and safari

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.

See this blog post for an in-depth discussion.
