AngularJS的另外一種表單驗證方式是自動驗證，即透過directive來實現，除了AngularJS自帶的directive,還需要用到angular-auto-validate這個第三方module。

有關angular-auto-validate：

安裝：npm i angular-auto-validate
引用：
module依賴：var myApp = angular.module("app", ["jcs-autoValidate"]);

為了實現錯誤訊息在地化，還需要angular-localize這個第三方module：

安裝：npm install angular-localize --save
module依賴：var myApp = angular.module("app", ["localize"]);
引用：

<script src="../node_modules/angular-sanitize/angular-sanitize.min.js"></script>
<script src="../node_modules/angular-localize/angular-localize.min.js"></script>

此外，當點擊提交表單按鈕，需要停用按鈕並顯示一種等待效果，需要用到angular-ladda這個第三方module:

安裝：bower install angular-ladda --save
module依賴：var myApp = angular.module("app", ["angular-ladda"]);
引用：

<link rel="stylesheet" href="../bower_components/ladda/dist/ladda-themeless.min.css"/>

<script src="../bower_components/ladda/dist/spin.min.js"></script>
<script src="../bower_components/ladda/dist/ladda.min.js"></script>
<script src="../bower_components/angular-ladda/dist/angular-ladda.min.js"></script>

<div class="container main-content" ng-controller="myCtrl1">
 <!--novalidate让表单不要使用html验证-->

    type="submit">
  <span ng-show="submitting">正在注册...</span>

  </button>

  {{formModel | json}}

<div class="form-group">  <button class="btn btn-primary" ladda = "submitting" data-style="expand-right" type="submit"> <span ng-show="submitting">正在注册...</span> <span ng-show="!submitting">注册</span> </button> </div>

其中,min, max為AgularJS的directive,而ng-min-err-type是angular-auto-validate的directive。這裡遵循的慣例是ng-AngularJS表單驗證的directive名稱-err-type，而tooYoung和tooOld的作用是什麼，又是在哪裡用上了呢？

以上就是本文的全部內容，希望對AngularJS手動表單驗證能夠熟練操作。
