php - Yii form textarea character limit -


i trying implement limit character showing user in textarea. code snippet seems not working. please me find error. 

 <?php echo $form->textarea($model, 'tr_summary', array('rows' => 2, 'cols' => 50, 'class' => 'form-control fldrequired')); ?> <div class="errormessage tour_tr_summary"></div>  <script type="text/javascript">    $(".fldrequired").keyup(function(e) {   fldid = $(this).attr('id');   if(fldid == 'tour_tr_summary' && $(this).val().length > 20) {     $('.'+fldid).html( 'maximum 20 characters allowed');     e.preventdefault();   }  });   </script>

this coding work textfield not textarea.

no javascript needed if don't care old browsers. add textarea() 1 more parameter:

array('maxlength'=>10)
