● 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
● 對表單的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表單的所有屬性都打印出來

{
 "$error": {
 "required": [
  {
  "$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": [

 ],
 "$viewChangeListeners": [],

 "$touched": false,
 "$pristine": true,
 "$dirty": false,
 "$valid": true,
 "$invalid": false,
 "$error": {},
 "$name": "sex",
 "$options": null
 }
}

以上，凡是有name屬性的input都被顯示在上面。

在second.js文件中定義了module,controller以及提交表單的方法。

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);
 };
});

以上的表單驗證方式好處是可控性強，但相對繁瑣。

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。
