title: Jquery check for integer?
body: <p>I have this code:</p>
  
  <pre><code>    jQuery(function( $ ){
  
      // If no speed is set (when loading the page) set default speed
  
      if (!$moveSpeed) {
          var $moveSpeed = 4000;
      }
  
      // Move the damn autocue
  
   $('a.goDown').click(function(){
          alert($moveSpeed);
    $.scrollTo('#footer', $moveSpeed);
    return false;
   });
  
      $('a.goUp').click(function(){
          alert($moveSpeed);
    $.scrollTo('#header', $moveSpeed);
    return false;
   });
  
  
      // Speed settings for autocue
  
      $('a.changeSpeed').click(function(){
    $moveSpeed = $(this).attr('speed');
    return false;
   });
  });
  
  &lt;/script&gt;
  </code></pre>
  
  <p>and if the changeSpeed is clicked, the alert box shows it is changed to the given number but it aint an integer, is there a way to convert a variable in to an integer? </p>
  
  <p>thx :)</p>
