AngularJS的表单验证大致有两种，一种是手动验证，一种是自动验证。
一、手动验证
所谓手动验证是通过AngularJS表单的属性来验证。而成为AngularJS表单必须满足两个条件：
1、给form元素加上novalidate="novalidate"；
2、给form元素加上name="theForm"，如下：
<!DOCTYPE html> <html lang="en" ng-app="myApp1"> <head> <meta charset="UTF-8"> <title></title> <link href="https://www.jb51.net/node_modules/bootstrap/dist/css/bootstrap.min.css"/> <link href="https://www.jb51.net/css/main.css"/> </head> <body> <nav > <div> <div> <a href="https://www.jb51.net/">Form Submitting</a> </div> </div> </nav> <div ng-controller="myCtrl1"> <!--novalidate让表单不要使用html验证--> <!--theForm变成scope的一个字段--> <form ng-submit="onSubmit(theForm.$valid)" novalidate="novalidate"> <div> <label for="name">Name</label> <input type="text" ng-model="formModel.name"/> </div> <div ng-class="{ 'has-error': !theForm.email.$valid && (!theForm.$pristine || theForm.$submitted), 'has-success': theForm.email.$valid && (!theForm.$pristine || theForm.$submitted) }"> <label for="email">Email</label> <input type="email" ng-model="formModel.email" required="required"/> <p ng-show="theForm.email.$error.required && (!theForm.$pristine || theForm.$submitted)">必填</p> <p ng-show="theForm.email.$error.email && (!theForm.$pristine || theForm.$submitted)">email格式不正确</p> </div> <div> <label for="username">Username</label> <input type="text" ng-model="formModel.username"/> </div> <div> <label for="age">Age</label> <input type="number" ng-model="formModel.age"/> </div> <div> <label for="sex">Sex</label> <select ng-model="formModel.sex"> <option value="">Please choose</option> <option value="male">Mail</option> <option value="femail">Femail</option> </select> </div> <div> <label for="password">Password</label> <input type="text" ng-model="formModel.password"/> </div> <div> <button type="submit">Register</button> </div> <pre> {{theForm | json}} </pre> </form> </div> <script src="https://www.jb51.net/node_modules/angular/angular.min.js"></script> <script src="https://www.jb51.net/second.js"></script> </body> </html>
● 给form加上novalidate="novalidate"意味着表单将不再使用HTML5验证特性
● 给form加上name="theForm"意味着表单的名称是theForm。如何使用theForm,比如我们验证表单是否被修改过theForm.$submitted
● 通过ng-submit提交表单
● formModel是$scope中的一个属性
● 对表单的Email进行了手动验证，使用了AngularJS表单的众多属性，比如theForm.email.$valid，theForm.$pristine，theForm.$submitted， theForm.email.$error.required，theForm.email.$error.email
● 通过<pre>{{theForm | json}}</pre>把AngularJS表单的所有属性都打印出来
{ "$error": { "required": [ { "$validators": {}, "$asyncValidators": {}, "$parsers": [], "$formatters": [ null ], "$viewChangeListeners": [], "$untouched": true, "$touched": false, "$pristine": true, "$dirty": false, "$valid": false, "$invalid": true, "$error": { "required": true }, "$name": "email", "$options": null } ] }, "$name": "theForm", "$dirty": false, "$pristine": true, "$valid": false, "$invalid": true, "$submitted": false, "email": { "$validators": {}, "$asyncValidators": {}, "$parsers": [], "$formatters": [ null ], "$viewChangeListeners": [], "$untouched": true, "$touched": false, "$pristine": true, "$dirty": false, "$valid": false, "$invalid": true, "$error": { "required": true }, "$name": "email", "$options": null }, "sex": { "$validators": {}, "$asyncValidators": {}, "$parsers": [], "$formatters": [], "$viewChangeListeners": [], "$untouched": true, "$touched": false, "$pristine": true, "$dirty": false, "$valid": true, "$invalid": false, "$error": {}, "$name": "sex", "$options": null } }
以上，凡是有name属性的input都被显示在上面。
在second.js文件中定义了module,controller以及提交表单的方法。
var myApp1 = angular.module('myApp1',[]); myApp1.controller('myCtrl1', function($scope, $http){ $scope.formModel = {}; $scope.onSubmit = function(){ $http.post('someurl',$scope.formModel) .success(function(data){ console.log(':)'); }) .error(function(data){ console.log(':('); }); console.log($scope.formModel); }; });
