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.
