javascript - Form validation using AngularJS not working -


i planning simple form validation using angularjs seems not working. here plunkr file: http://plnkr.co/edit/sepahszlfoflfb87uh8s.

i don't know why, seems not firing.

my html file:

<html>    <head>     <!-- css -->     <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css" />     <style>         body     { padding-top:30px; }     </style>     <!-- js -->     <script src="http://code.angularjs.org/1.2.6/angular.js"></script>     <script src="app.js"></script>   </head>    <body ng-app="validationapp" ng-controller="maincontroller">     <div class="container">       <!-- page header -->       <div class="page-header">         <h1>angularjs form validation</h1>       </div>       <!-- =================================================================== -->       <!-- form ============================================================== -->       <!-- =================================================================== -->       <!-- pass in variable if our form valid or invalid -->       <form name="regform" ng-submit="submitform(regform.$valid)" novalidate>         <!-- name -->         <div class="form-group item item-input" ng-class="{ 'has-error' : regform.name.$invalid && (regform.name.$dirty || submitted)}">                   <input type="text" name="name" class="form-control" ng-model="user.name" placeholder="full name" ng-required="true">                   <br/>                   <p ng-show="regform.name.$error.required && (regform.name.$dirty || submitted)" class="help-block">please provide full name</p>             </div>             <div class="form-group item item-input" ng-class="{ 'has-error' : regform.email.$invalid && (regform.email.$dirty || submitted)}">                 <input type="email" name="email" class="form-control" ng-model="user.email" placeholder="email address" ng-required="true">                 <p ng-show="regform.email.$error.required && (regform.email.$dirty || submitted)" class="help-block">email required.</p>                 <p ng-show="regform.email.$error.email && (regform.email.$dirty || submitted)" class="help-block">enter valid email.</p>             </div>             <div class="form-group item item-input" ng-class="{ 'has-error' : regform.contactno.$invalid && (regform.contactno.$dirty || submitted) }">                 <input type="text" name="contactno" class="form-control" ng-model="user.contactno" placeholder="phone number" ng-pattern="^0[0-9]{2}[- ]?[0-9]{3} ?[0-9]{4,5}$" maxlength="11"  ng-required="true">                 <p ng-show="regform.contactno.$error.required && regform.contactno.$error.pattern && (regform.contactno.$dirty || submitted)" class="help-block">enter valid phone number.</p>             </div>             <div class="form-group item item-input" ng-class="{ 'has-error' : regform.org.$invalid && (regform.org.$dirty || submitted)}">                 <input type="text" name="org" class="form-control" ng-model="user.org" placeholder="organization name" ng-required="true">                 <p ng-show="regform.org.$error.required && (regform.org.$dirty || submitted)" class="help-block">please input name of organization</p>             </div>         <button type="submit" class="btn btn-primary">submit</button>       </form>     </div>   </body>  </html>

my js file:

var validationapp = angular.module('validationapp', []);  // create angular controller validationapp.controller('maincontroller', function($scope) {      // function submit form after validation has occurred                 $scope.submitform = function(isvalid) {          // check make sure form valid         if (isvalid) {              alert('our form amazing');         }      };  });

i need validate required fields have related input , not empty fields.

your ng-pattern should ng-pattern="/^[0-9]{2}[- ]?[0-9]{3} ?[0-9]{4,5}$/" instead of ng-pattern="^0[0-9]{2}[- ]?[0-9]{3} ?[0-9]{4,5}$" regx pattern should use escaping character / @ start & end of expression.
