Checking for focus

[Christoph Weber]

Hello,
is there a function with which I can find out if a form element has the
focus?
Something like:

function ReactIfFocus()
{
for(var i=0; i<10; i++)
if( HasFocus(docume nt.forms[0].elements[i])
makeSomething() ;
}

I need the function to move the focus to the next field.

Thanks
Christoph

There are event handlers onfocus and onblur that let you react to a
change of focus.
IE also has
if (document.activ eElement == document.forms[0].elements[i])

I did some quick Googling, and couldn't find anything like that.
What are you trying to do? The only suggestion I found is to
keep track of it or fire the desired function on the onfocus event.
