Randomize setInterval ( How to rewrite same random after random interval)
<p>I'd like to know how to achieve:
generate a random number after a random number of time. And reuse it.</p>

<pre><code>function doSomething(){
     // ... do something.....
}

var rand = 300; // initial rand time

i = setinterval(function(){

     doSomething();
     rand = Math.round(Math.random()*(3000-500))+500; // generate new time (between 3sec and 500"s)

}, rand); 
</code></pre>

<p>And do it repeatedly.</p>

<p>So far I was able to generate a random interval, but it last the same until the page was refreshed (generating than a different time- interval).</p>

<p>Thanks</p>
