Javascipt: counting chars!
I have amended a javascript function i found on the web to count charecters within a textbox as i write in it. This works...
Code = Code:
<html>
<head>
<title></title>
<script type="text/javascript" >
function CheckFieldLength(fn,wn,rn,mc) {
var len = fn.value.length;
if (len > mc) {
fn.value = fn.value.substring(0,mc);
len = mc;
}
document.getElementById(wn).innerHTML = len;
}
</script>
</head>
<body bgcolor="#ffffff" >
<form name=form1 method=post action='http://www.plus2net.com'>
<textarea name="product_profile" cols="120" rows="15" class="formelement" id="taMessage" onkeyup="CheckFieldLength(taMessage, 'charcount', 'remaining', 10000);" onkeydown="CheckFieldLength(taMessage, 'charcount', 'remaining', 10000);" onmouseout="CheckFieldLength(taMessage, 'charcount', 'remaining', 10000);"></textarea>
<strong>Contains <span id="charcount" class="compulsory">0</span> characters entered. </strong></p>
</form>
</body>
</html>
