Answer 2

A:

There is afaik never been a cross browser script for this. The solution is to NOT rely on undocumented and changeable features of a specific browser to detect something that is important.

Since you have a CHILD page, you can set up a test in the parent (opener) that at intervals test the childWindowHandle.closed property and acts on that.

Hi,

I can detect the tab close event in IE and FireFox.

Then i want to detect newtab close event in other browser (Not refreshing child page)

Main.jsp

<body>
<a href="child.jsp" target="_blank">New Tab</a>
</body>

child.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; 

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
     <script type="text/javascript">

            function doUnload()
            {                    
                if(navigator.userAgent.toLowerCase().indexOf("firefox") > 0)
                {
                    var winWidth = document.body.clientWidth;
                    var winHeight = document.body.clientHeight;                   
                    if ((winWidth <= 0) || (winHeight <= 0) || (winWidth <= -80))
                    {
                      alert("Child Tab is closing in FF");                        
                    }
                }

                if(navigator.appName == "Microsoft Internet Explorer")
                {
                    if ((window.event.clientX < 0) || (window.event.clientY < 0) || (window.event.clientX < -80))
                    {
                        alert("child tab is closing in IE");                        
                    }
                }                                       
            }

        </script>
</head>
<body onunload="doUnload()">   

    <h1>This is Chile Page.</h1>

</body>
</html>

Similarly, I want to show the message "child tab is closing" when i close the child tab in other browser. like Opera, Google Chrome etc.

Help me about this. Thanks in advance.
