I am currently creating a page in html, but I would like you to click on the main button to close a window, I mean ...

and that I get a popup window with a message of caution ... I found that they do with javascript but with a button or link, but there will be to be treated directly with the main button to close.

 <!DOCTYPE html>
 <html>
<head>
  <title>emergente</title>
</head>
<script type="text/javascript">
    window.addEventListener("beforeunload", function (e) {
    var confirmationMessage="\o/";

    e.returnValue= confirmationMessage;
    return confirmationMessage;
    });
</script>
<body >

</body>
</html>

javascript html

You can use the beforeunload event from javascript, for example:

window.addEventListener("beforeunload", function (e) {
  var confirmationMessage = "\o/";

  e.returnValue = confirmationMessage;     // Gecko, Trident, Chrome 34+
  return confirmationMessage;              // Gecko, WebKit, Chrome <34
});

Note

It is important that you know that you can not put a confirm/alert   inside the event beforeunload .



The texts are different for each browser.


Not all browsers support changing the text.
