AngularJS的表單驗證大致有兩種，一種是手動驗證，一種是自動驗證。
手動驗證:
是通過AngularJS表單的屬性來驗證。而成為AngularJS表單必須滿足兩個條件：1、給form元素加上novalidate="novalidate"；2、給form元素加上name="theForm".
<!DOCTYPE html><html><head lang="en"> <meta charset="UTF-8"> <title></title> <script src="https://cdn.bootcss.com/angular.js/1.4.6/angular.min.js"></script></head><body> <form ng-app="myApp" ng-controller="validateCtrl" name="myForm" novalidate="novalidate"> <p> 使用者名稱 <input type="text" name="user" ng-model="user" required/> <span style="color:red" ng-show="myForm.user.$error.required">必填項</span> </p> </form></body><script> var app = angular.module(‘myApp‘,[]); app.controller(‘validateCtrl‘,function($scope){ $scope.user = ‘dddddd‘ })</script></html>
● 給form加上novalidate="novalidate"意味著表單將不再使用HTML5驗證特性
● 給form加上name="theForm"意味著表單的名稱是theForm。如何使用theForm,比如我們驗證表單是否被修改過theForm.$submitted
● 通過ng-submit提交表單
● formModel是$scope中的一個屬性
● 對錶單的Email進行了手動驗證，使用了AngularJS表單的眾多屬性，比如theForm.email.$valid，theForm.$pristine，theForm.$submitted， theForm.email.$error.required，theForm.email.$error.email
● 通過<pre>{{theForm | json}}</pre>把AngularJS表單的所有屬性都列印出來
