How can I ensure that the alert event is triggered only once at the 15-second mark of a 45-second video? The code snippet below initiates the alert, but how can I modify it to make sure the alert only appears once.
var video = document.getElementById("media");
video.addEventListener('timeupdate', function(e) {
if (e.target.currentTime == 15000);
alert("Hello! I am an alert box!!");
}, false);
The code provided may not be effective because there is no guarantee that the current time will reach 15000 milliseconds during each timeupdate event. It would be more reliable to use the setTimeout function in JavaScript instead.
Here's an example of how you can implement this:
video.play();
var timeout = setTimeout(function(){
alert("Hello! I am an alert box!!");
}, 15000);
If you need to cancel the timeout, simply use the clearTimeout method:
clearTimeout(timeout);
Feel free to correct me if I am mistaken.
