[Javascript] A loop for this script? Is it really possible?

[Roland Dong]

Is it possible to pass the value to:
document.getElementById(value_to_be_passed).onmouseover=function(){....}

I tried many tricks without success. I started wondering if it is really
possible.  I do not understand why it works if you hard coded value:

Document.getElementById("tutorials").onmouseover=function(){....} but you
can never replace "tutorials" with any dynamic value?  I even tried

f="tutorial";
Document.getElementById(f)onmouseover=function(){....} but it is still not
working.  That drives me nut!



>A quick fix would be to precalculate the id and put it in the string:

>  var id= ids[i];
>  var f= 'document.getElementById("'+id+'").style.visibility= "hidden"';
>  var timer= window.setTimeout(f, 500)
