random letter

lepierrot

if I set :

var $alphabet = "abcdefghijklmnopqrstuvwxyz";
var $new_letter = " ";
$new_letter = $alphabet.charAt(Math.round(26 * Math.random()));

It should return me a random letter no ?
Because it doesn't work ...
Is there an inclusion I 've missed ?

Hi lepierrot,

I tried using your code and it works fine when i test it in evaluate window of the sahi controller. Where exactly are you facing the problem?

Hi Pankaj,

It's ok I've found the solution. It was in the declaration of my variable...
It works perfectly and I've created a randomly string generating function!

If anybody 's interested, let me know.

Thats great!!

Ya that piece of code will be handy. I also need to generate some names on fly.

As promised :

function random_string($length_str){
    var $alphabet = "abcdefghijklmnopqrstuvwxyz";
    var $rand_str = ""; // string you want to create
    var $number_str = 0; // rank of the current letter 
    var $new_letter ;
    for($l=0;$l<$length_str;$l++){
        $new_letter = $alphabet.charAt(Math.round(26 * Math.random()));
        $rand_str += $new_letter;
        $number_str++;
    }
    return $rand_str; 
}

with : length_str = length of the random string you want to create
