HELP with Timer...

[Mel]

I have an entry field and a long number "33424JHKJHKJ43 432423" as well
as a submit button "FINISHED".

I need to know "HOW LONG" it takes for the user to enter the number
correctly ! if incorrect, it should popup an alert and ask user to
correctly enter the number again and then press FINISHED button

Can someone help me a little Codelet ?

thanks

Mel, lets see if this is enough to get you started:
<script>
function userKeyDown(){
if(!arguments.c allee.start){
arguments.calle e.start = new Date();
}
}
function validate(){
var start = userKeyDown.sta rt;
if(start) {
var finished = (new Date()).getTime ();
var diff = finished - start.getTime() ;
userKeyDown.sta rt = null;
alert("User took " + diff + " milliseconds to fill field");
}else{
alert("no start time");
}
// Validate your form field here
}
</script>

<form>
<input type="text" onkeydown="user KeyDown();">
<input type="button" onclick="valida te()" value="finished " />
</form>
