You wanna try some simple JS:
http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_length_string
Edit and Click:
<html>
<body>
<script type="text/javascript">
var myString = "123456";
var length = myString.length;
document.write("The string is this long: " + length);
</script>
</body>
</html>
And you get as output:
The string is this long: 6
