PHP Javascript Div刷新

Question

I'm refreshing a div every 20 seconds on a page. The code refreshes the div but also nests a div inside of itself.

<script>
  setInterval(function(){
  $("#open").load("test.php #open");
  }, 20000);
</script>

Before javascript reload:

<div id="open">
  <p>Testing</p>
</div>

After javascript reload:

<div id="open">
    <div id="open">
        <p>Testing</p>
    </div>
</div>

No matter how long the page sites there it will always just have one nested div after the javascript runs. How do I get this to not load another nested div?

Answer 1

I presume test.php returns <div id="open">(blah)</div> ?

Try:

$("#open").load("test.php #open").children( ).unwrap( );

Although you should really change the php script.
