Let us revisit Beetle's Code Challenge! (http://www.codingforums.com/showthread.php?threadid=12285&goto=newpost) with a new twist:

Implement the string reversing function in as few characters as possible! (And use all the semicolons you like...)

Use this declaration:

function convert(t){ /*your most compact code here!*/ }

Assume that the t parameter is a textfield element thusly...

<html>
<head>
<title>Contest</title>
<script type="text/javascript">

function convert( inputObject )
{
var stringIn = inputObject.value;
var stringOut = "";
for ( var i = stringIn.length; i >= 0; i-- )
{
stringOut += stringIn.charAt(i);
}
inputObject.value = stringOut;
}

</script>
</head>

<body>

<form>
<input type="text" name="text1" size="80" />
<br />
<input type="button" value="convert" onclick="convert( this.form.text1 );" />
</form>

</body>
</html>

On your mark, get set, code!

Before mordred grabs it:

t.value=t.value.split('').reverse().join('')

:p

I'd be impressed to see it go smaller than that.

Me too! If I ever need to reverse a string (although I can't imagine why), I'll definitely be using that version... ;)
