body: <p>I want to change setInterval function time when my code is running.</p>
  
  <p>I try this </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
          $(function () {
              var timer;
              function come() { alert("here"); }
              timer = setInterval(come, 0);
              clearInterval(timer);
              timer = setInterval(come, 10000);
          });
      &lt;/script&gt;
