<div class="form-group" ng-class="{ 'has-error' : myform.name.$invalid && (myform.$submitted  || myform.name.$touched ) }">     <label for="username" style="color:#767676" class="" ng-hide="myform.name.$invalid && (myform.$submitted  || myform.name.$touched )">name</label>     <label class="error_message_text" ng-show="myform.name.$invalid && (myform.$submitted  || myform.name.$touched )">         please enter name     </label><br>     <input type="text" name="name" class="form-control" ng-class="" ng-model="user.name" required/> </div>
