$(window).blur event affecting Iframe

Question

I want to detect when the user leaves my page( e.g open a new tab) so I can stop a countdown. I did it using:

$(window).blur(function() {
 //stop countdown
}         


        

Answer 1

Because of the isolation of the iframe, clicking inside it counts as a blur for the parent. If the content of the iframe could be brought in with ajax, that would be a better option.
