jquery.form.js:357 uncaught typeerror:  object function (a,b){return new d.fn.init(a,b,g)} has no method 'handleerror'

here code,

<form id="employeeaddform" class = "classform" enctype="multipart/form-data" action="inc/employeeadd.php"  method="post">         <p><input type="file" size="32" name="my_field" value="" /></p>         <p class="button"><input type="hidden" name="action" value="image" />          <label for="nname">personal name : </label>          <input name="nname" id="nname" type="text" tabindex="11" />         <br />          <label for="ninformation">information : </label>         <textarea id="ninformation" name="ninformation"></textarea>          <div align="center">             <input id="button1" type="submit"/>              <input id="button2" type="reset" />         </div> </form>  <script type="text/javascript"> $(document).ready(function(){         var options_employeeadd = {                  beforesubmit:  validate_employeeadd,  // pre-submit callback                  success:       showresponse_employeeadd  // post-submit callback                                     };          $('#employeeaddform').ajaxform(options_employeeadd); });          function validate_employeeadd(formdata, jqform, options) {...}          function showresponse_employeeadd(responsetext, statustext, xhr, $form)  {...}

the latest version of jquery form doesn't use 'handelerror'. download here: https://github.com/malsup/form/blob/master/jquery.form.js
