I use the following ajax code to load html page:

```
var AJAX = {
            request:false,
            createHttpRequest:function()
            {
                //initiate HttpRequest for AJAX calling
                if (!AJAX.request && typeof XMLHttpRequest!='undefined') 
                {
                    try 
                    {
                        AJAX.request = new XMLHttpRequest();
                    } 
                    catch (e) 
                    {
                        AJAX.request=false;
                        alert("This Browser Does not Support AJAX");
                    }
                }
                if (!AJAX.request && window.createRequest) 
                {
                    try 
                    {
                        AJAX.request = window.createRequest();
                    } 
                    catch (e) 
                    {
                        AJAX.request=false;
                        alert("This Browser Does not Support AJAX");
                    }
                }

              },
              call:function(method,url,asyn)
              {
                  AJAX.request.open(method,url,asyn);

              send:function(value)
              {
                  AJAX.request.send(value);
              }
          }

    <tr>
        <td colspan="3"  height="80px" class="ui-widget-shadow" align="center">
            <span   style="font-family:verdana;font-size: 26px;font-weight: bold; text-align: center;color:#fff" ></span>
            <span   style="text-align: right; float:right;" ><img height="55px" width="55px" src="images/m1.jpg" /></span>
        </td>
    </tr>
    <tr>
        <td colspan="3"  height="25px"  align="center">
            <span style="float:right;">Welcome Mr. <?php echo $u; ?>|&nbsp;&nbsp;<a href="logout.php">logout</a></span>

    </tr>
    <tr>
        <td colspan="3"  height="2px" bgcolor="#828282" align="center">

        </td>
    </tr>
    <tr>
        <td width="180px" valign="top" align="center" height="100%" >
            <?php include("tiles/leftMenu.php");?>
        </td>
        <td width="5" bgcolor="#828282">
        </td>
        <td align="center"  valign="top">
