JavaScript alert box with timer

I want to display the alert box but for a certain interval. Is it possible in JavaScript?

Answer

If you want an alert to appear after a certain about time, you can use this code:

setTimeout(function() { alert("my message"); }, time);

If you want an alert to appear and disappear after a specified interval has passed, then you’re out of luck. When an alert has fired, the browser stops processing the javascript code until the user clicks “ok”. This happens again when a confirm or prompt is shown.

If you want the appear/disappear behavior, then I would recommend using something like jQueryUI’s dialog widget. Here’s a quick example on how you might use it to achieve that behavior.

var dialog = $(foo).dialog('open');
setTimeout(function() { dialog.dialog('close'); }, time);
