安裝：npm i angular-auto-validate
引用：<script src="../node_modules/angular-auto-validate/dist/jcs-auto-validate.min.js"></script>
module依賴：var myApp = angular.module("app", ["jcs-autoValidate"]);

為了實現(xiàn)錯誤信息本地化，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，需要禁用按鈕并顯示一種等待效果，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>

先看提交按鈕：

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

ladda屬性值為bool值，true表示顯示動態(tài)等待效果，false不顯示動態(tài)等待效果，這里的submitting是scope中的一個屬性
data-style="expand-right"表示在按鈕的右側(cè)顯示動態(tài)等待效果

再拿表單中的Age字段來說：

<div class="form-group">
 <label for="age" class="control-label">Age</label>
 <input type="number"
   class="form-control"
   id="age"
   ng-model="formModel.age"
   required="required"
   min="18"
   max="65"
   ng-min-err-type="tooYoung"
   ng-max-err-type="tooOld"
 />
</div>

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

是在module層面用上了，定義在了form_validation_auto.js文件中。

var myApp1 = angular.module('myApp1',['jcs-autoValidate','localize','angular-ladda']);

myApp1.run(function(defaultErrorMessageResolver){
 defaultErrorMessageResolver.getErrorMessages().then(function(errorMessages){
  errorMessages['tooYoung'] = '年齡必須小于{0}';
  errorMessages['tooOld'] = '年齡不能大于{0}';
  errorMessages['badUsername'] = '用戶名只能包含數(shù)字、字母或下劃線';
 });
});

myApp1.controller('myCtrl1', function($scope, $http){
 $scope.formModel = {};
 $scope.submitting = false;

 $scope.onSubmit = function(){

  $scope.submitting = true;
  console.log('已提交');
  console.log($scope.formModel);

  $http.post('url',$scope.formModel)
   .success(function(data){
    console.log(':)');
    $scope.submitting = false;
   })
   .error(function(data){
    console.log(':(');
    $scope.submitting = false;
   });
 };
});

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