You can write your own function for that using the s.charAt();

[iam_clint]

<script>
function reverse() {
var text = document.getElementById("rtext").value;
var reversed = "";
for (i=text.length; i>=0; i--) {
reversed = reversed + text.charAt(i);
}
document.getElementById("reversed").value = reversed;
}
</script>
<input type="text" id="rtext" value="insert text"><input type="text" id="reversed" value="The Text Reversed"><input type="button" value="Click Me" onclick="reverse();">
 

Generic Example I wrote for you.

str='abcdefghijklmnopqrstuvwxyz';

alert(str.split('').reverse().join(''));

returns >> 'zyxwvutsrqponmlkjihgfedcba'

Yes, it's an Array object method, see here. However, I wouldn't have thought of that cryptic solution! Nicely done, mrhoo.

<script>
function reverse() {
var text = document.getElementById("rtext").value;
var reversed = "";
for (i=text.length; i>=0; i--) {
reversed = reversed + text.charAt(i);
}
document.getElementById("reversed").value = reversed;
}
</script>
<input type="text" id="rtext" value="insert text"><input type="text" id="reversed" value="The Text Reversed"><input type="button" value="Click Me" onclick="reverse();">

How about making it even more generic:

function revStr(str) {
var reversed = "";
for (i=str.length; i>=0; i--) {
reversed += str.charAt(i);
}
return reversed;
}

Now add it to the String object:

String.prototype.reverse = strRev;

and use as follows:

var str = 'myString';
alert(str.reverse());
