title: reset 'random' math
body: <p>I've got a random generator my using arrays and the following string to randomize:</p>
  
  <pre><code>var doelgroepRand = doelgroepArray[Math.floor(Math.random() * doelgroepArray.length)];
  </code></pre>
  
  <p>/</p>
  
  <pre><code>var divergeerIdee = 'Laat een' + ' ' + doelgroepRand + ' ' + watRand + ' ' + handelingRand
  </code></pre>
  
  <p>This goes into</p>
  
  <pre><code>$('#something').click( function() { 
  event.preventDefault();
  alert(divergeerIdee); });
  });
  </code></pre>
  
  <p>But to get a new set of random items, you need to refresh the page.
  I want that, on click, everything is 'resetted' and you get new random items.</p>
  
  <p>What is the string I need?</p>
