I have a cold fusion file that I will be loading data into from a cfquery.  The cfm file has ajax that allows an edit in place for comments that will be posted to a database.  I need the results from the query to be posted in the div when the page loads.  I can add comments to the page but i do not know how to load the comments from the database.  I included the cfm file and the javascript that writes to the div.  Please let me know if i need to provide more information.  
HTML/CFM code

----------------------------------------------------------------------

<script type="text/javascript" src="ajax.js"></script>

    <script type="text/javascript" src="formdata2querystring.js"></script>

    <script type="text/javascript" src="blog.js"></script>

    <link rel="stylesheet" href="blog.css" type="text/css"/>

  </head>

  <body>

 <cfquery name="getcomments" datasource="#datasource#">

  select comment from comment

</cfquery>

    <form id="blogForm" method="post" action="">

      <div>

        <input type="hidden" id="editEntryId" name="editEntryId" value="" />

        <div id="colDiv">

          <div id="promptDiv"><!--- (Double-click any entry to edit) ---></div>

          <div id="newEntryButtonDiv">

            <input type="button" id="newEntryButton" name="newEntryButton" class="inputButton" value="New Entry" />

          </div>

          <div class="clearBoth"></div>

          <div id="allEntryDiv"></div>

        </div>

      </div>

    </form>
