Web forms

Hi all

Does anyone know of a good script that does a character count when entering text into a field on a form. Basically, I have a field on a form limited to xx characters and need the user to see how many characters they have already entered.

All suggestions welcomed!

<SCRIPT LANGUAGE="JavaScript">
<!--
/*function textCounter(field,cntfield,maxlimit)
{
if (field.value.length > maxlimit) // if too long...trim it!
field.value = message1.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else
cntfield.value = maxlimit - field.value.length;
}
*/
function ad_limit()
{
if (document.form.body.value.length > 250)//maxlimit
document.form.body.value.substring(0,250),
alert("There is a limit of 250 characters for per message.\nYour message contains "+ document.form.body.value.length +" characters.\nPlease refine your message.");
else
document.form.remLen1.value = 250 - document.form.body.value.length;
}

//-->
</SCRIPT>

<FORM NAME="form" METHOD="post" ACTION="insert_ad.asp" onSubmit="return formcheck()">
<TEXTAREA NAME="body" COLS="50" ROWS="5" onKeyUp="return ad_limit()" onChange="return ad_limit()"></TEXTAREA>
<INPUT readonly TYPE="text" NAME="remLen1" SIZE="3" MAXLENGTH="3" VALUE="250"> characters left
<INPUT TYPE="SUBMIT" VALUE="Proceed" NAME="Submit">
</FORM>
