Refresh contents of a div

I have a div that displays text from a php session:

<div id="sessioncontent">
<?php if (isset( $_SESSION['returntext'])){ echo  $_SESSION['returntext'];} ?>
</div>

I have a javascript method that calls another php script which changes the text within that session variable. At the end of the method, I want the div to refresh so that the new text within the session is echoed. I have tried the following line but it doesnt work:

document.getElementById("sessioncontent").innerHTML = document.getElementById("sessioncontent").innerHTML;

You are replacing content with the same content. I would suggest making an ajax call and then populating your div with the response from the ajax call. Something like this:

$.ajax({
  url: yourUrl,
  method: 'get', // or 'post'
  success: function (response) {
      $('#sessioncontent').html(response);
  }
  // other ajax options here if you need them
});

Too, complicated. First, display the initial div content w/ out the PHP code (i.e. the output of the PHP). Second, your wording doesn't makes complete sense - JavaScript does not call PHP. I'm going to assume you mean Ajax. Once you get the new session variable from an ajax call, then you can update your div dynamically.

I think you are a bit fuzzy on your concepts, which is fine, I'm sure that is why you posted.
