Checking if the cursor is in an input field

Is there anyway I can check if the cursor is an input field? I need a function that determines if the cursor is in any input field on the page.

Thanks!

Code:

...
<script language="JavaScript" type="text/javascript">
<!--
function set_inputs(){
var inp = document.getElementsByTagName('INPUT');
for(var i = 0; i < inp.length; i++){
if(inp[i].type && (inp[i].type=="text")){
inp[i].onfocus = function(){alert('The cursor is in there!');}
}
else{continue;}
}
}

window.onload = set_inputs;
//-->
</script>
</head>
<body>
...

You need the onmouseover and onmouseout (onfocus is for focusing the field, i.e. clicking in it or tabbing to it).

Code:

<input onmouseover="alert('Mouse is in here');" onmouseout="alert('mouse is not here');">

If you tell us why you need to do this, and what problem you are trying to solve we can be of more help.

Sorry should have made myself clearer.

I am writing a firefox extension that needs to recognize when the user focuses (clicks or tabs into) on an input field. I tried the code from the first reply but for some reason it returned only empty arrays.
