Adding simple condition with jQuery to see if input is focused?

Question

I want to set a simple condition inside the loop so that the code inside is only run if any input is focused or if any element in the body is focused. How do I do each thing?

setInterval(function(){
  document.getElementById('clickMe').style.display= "block";  
}, 1000 );

thanks

Have a look at some of the other posts about how to determine where the focus is. — nnnnnn

Use the W3C document.activeElement proprety to see which element is focused (also documented at MDN).

Note that this property is introduced in HTML5 and may not be widely implemented, so test for support and expect it not to be supported in a reasonable percentage of clients.

I thought there was a simple solution with js. Isn't there? I'd rather do something that works in all browsers

What RobG posted is the simple solution. If you want it to work in all browsers (including what, Netscape? IE5?) it gets more complicated.

The SO post Which browsers support document.activeElement? might be of interest.
