below html form need display calendar object (tcal) instantiated in script tag:

<form onsubmit="" action="" method="post" name="newdoc">          <table border="0" style="border: medium none;" id="docfield">           <tbody>           <tr>             <td style="border-right: medium none;">                 date             </td>          <td style="border-right: medium none;">             <input type="text" value="" maxlength="10" name="test" style="width: 100px;" id="date">         <script>          new tcal ({         'formname': 'newdoc',         'controlname': 'test'          });      </script>         </td>      </tr>     </tbody>  </table> </form>

i not getting calendar displayed...

i see javascrip in response html, never executed if html coming through ajax call. try put javascript 

new tcal ({ 'formname': 'newdoc', 'controlname': 'test' });
after xmlhttprequest object fetches , puts data in '#docfields'.

 if (req.readystate==4) {    if (req.status==200)    {       document.getelementbyid('docfields').innerhtml="";       if(req.responsetext != '')       {           document.getelementbyid('docfields').innerhtml=req.responsetext; //retuen value           /** here **/           new tcal ({'formname': 'newdoc','controlname': 'test'});           /** here **/       }       else       {           document.getelementbyid('docfields').innerhtml="no fields available";       }    } }

hope help.
