title: How to refresh an iFrame with AJAX every 5 seconds?
body: <p>I am trying to refresh an iFrame with AJAX so the iFrame on my page doesn't blink. The code below works, but it's a major memory hog and it crashes the page after about 2 minutes. I'm trying to get this to work so it doesn't crash the page. </p>
  
  <p>I'm using the iFrame which has a table in it and I want it to get the content every 2 seconds so it's updated. The AJAX code below is inside a page called table.php. I have this page (table.php) in an iFrame on my main page called dispatch1.php. The table id is "thistable". </p>
  
  <pre><code>&lt;script&gt;
      function checkRequest(){
        var interval = setInterval(function(){
        var request = $.ajax({
          url: "table.php",
          type: "post",
          datatype: "html"
        });
        request.done(function(msg){
          $("#thistable").html(msg);
        });
        },2000)
       }
      &lt;/script&gt;
  </code></pre>
