A technique for detecting when a user leaves a page.
const captureLeavingPage = () => {
window.onbeforeunload = function (evt) {
var message = "Are you sure you want to leave?";
if (typeof evt == 'undefined') {
evt = window.event;
}
if (evt) {
evt.returnValue = message;
}
return message;
}
}
</script>
I am now looking to track when a user clicks "leave this page" and save that action to a database. How can I achieve this?
If you choose not to display the dialog, you can attempt to catch the user as they leave the page. Keep in mind that if you do decide to show the dialog, there are limited options available.
To achieve this, you must make a synchronous request to the server using onbeforeunload.
onbeforeunload = function() {
var data = 'id=456';
var xhr = new XMLHttpRequest;
xhr.open('POST', '/leavingpageevent', false);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.setRequestHeader("Content-length", data.length);
xhr.send(data);
}
It's important to note that this method may not always work reliably. The onbeforeunload event is not standardized, and some browsers might not send the request at all.
In my experience with Chrome, however, I have found this approach to be mostly effective.
