Javascript - generating a random number of specified length from set of specified values
<p>I wanted to generate a random number 32 characters in length from a specified set of characters.</p>

<p>For example:</p>

<pre><code>var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZ";
var string_length = 32;
</code></pre>

<p>Which would then return a random number of length 32 using the specified characters. </p>
