[AngularJS] 重置表单class ng-dirty

在表单提交之后,如果仅仅是清空表单数据内容,相应 inputclass 并不会改变(依然是 ng-dirty 状态),我们需要移除这些红色的 required 提示。

    <div ng-app="myApp" ng-controller="myCtrl as ctrl">
      <form name="ctrl.myForm">
        <div><label for="email">Email</label>
        <input name="myInput" type="email" ng-model="ctrl.email" id="email" required></div>
        <div><label for="password">Password</label>
        <input name="myPassword" type="password" minlength="8" ng-model="ctrl.password" id="password" required></div>
        <div>
        <button ng-click="ctrl.reset()" type="button">Reset</button>
        </div>
      </form>
`</pre>

`JavaScript` 代码:

<pre>`
angular.module('myApp', [])
    .controller('myCtrl', myCtrl);

function myCtrl(){
    var vm = this;
    vm.reset = function(){
        vm.myForm.$setPristine();
        vm.myForm.$setUntouched();
        vm.email = vm.password = '';
  }
}

表单input区域必须放在 form
