Detect if window is in focus or not


Recommended Posts

http://www.steelbreeze.us/play_ground/isfocused.html

 

I made an example script that displays the text box that has focus when any of the three text boxes are clicked.

 

The key is:

 

document.activeElement

 

which shows what element is currently focused.

 

Works in FF 3, IE 7/8 (haven't tested any others...)

It's part of HTML 5, so IE 6 prolly doesn't like this.
