AngularJS手动表单验证

更新时间：2026-03-29 01:21:14作者：fang

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>

<head>

</head>

<body>

<a href="/" class="navbar-brand">Form Submitting</a>

</div>

</nav>

</div>

<div class="form-group" 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>

<p class="help-block" ng-show="theForm.email.$error.email && (!theForm.$pristine || theForm.$submitted)">email格式不正确</p>

</div>

<label for="username">Username</label>

</div>

</div>

<option value="">Please choose</option>

<option value="femail">Femail</option>

</select>

</div>

<label for="password">Password</label>

</div>

<button class="btn btn-primary" type="submit">Register</button>

</div>

<pre>

</pre>

</form>

</div>

</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);

};

});

以上的表单验证方式好处是可控性强，但相对繁琐。

以上就是本文的全部内容，希望对AngularJS手动表单验证能够熟练操作。
