为什么Wordpress在滑入和滑出时会评论我的.entry-content？

I'm trying to make the content of my Wordpress posts slide into view when the title of the post is clicked.

The code I'm using is as follows:

<script type="text/javascript">
 jQuery(document).ready(function() {
 jQuery(".entry-content").hide();
 //toggle the componenet with class msg_body
 jQuery(".entry-title").click(function()
 {
  jQuery(this).next(".entry-content").slideToggle(500);
});
});
</script>

Seems simple enough, but after implementing it all of a sudden my .entry-content class is being commented out.

Anyone seen this before?

Let me know if more details are necessary to explain! Thanks in advance!
