<body> tag only onload\onunload\onbeforeunload event, and no OnClose event. The OnUnload event is performed regardless of whether the page is closed or refreshed. How do I capture a page close?

The onload is only executed when the page loads

Only perform onunload when page closes

When the page is refreshed, execute onbeforeunload First, then onunload, and finally onload. So we can add a tag in the onbeforeunload and judge the tag in the onunload to determine if the page is really closed.

<title> determine if the page is closed or refreshed </title>

<body onunload= "fclose ();" onload= "fload ();" onbeforeunload= "bfunload ();" >
<script language= "JavaScript" >
var s = "Test";
function fclose ()
{
if (s== "no")
Alert (unload me!=+s+ This is the Refresh page!) ’);
Else
Alert (This is the closing page);
}

function Fload ()
{
Alert ("Load me!=" +s);
}

function Bfunload ()
{
s = "no";
}
</script>
</body>
