title: Using Javascript to read and display a txt file dynamically
body: <p>I was trying to read a txt file and display its content in my web page, since its content changes over time, I want to update it periodically. Here is my code, it displays the content at first, but it won't change after I changed the file's content. Any suggestions? Thanks.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
          setTimeout(read(),3000);
      function read(){
      setTimeout(jQuery.get('now.txt',function(data){
      document.write(data);}),1000);
      }
  &lt;/script&gt;
  </code></pre>
