The example in this article describes how to use JavaScript to detect whether the pop-up window has been closed. Share it with everyone for your reference. The specific implementation method is as follows:
var win = window.open('foo.html','windowName'," width=200,height=200,scrollbars=no");
var timer = setInterval(function() {
If(win.closed) {
,,,,,,,
alert('closed');
}
}, 1000);
I hope this article will be helpful to everyone’s JavaScript programming design.
