angularjs - 提交时重置表单

Question

我正在提交一个表单，然后将所有字段清空，但它不起作用。表单已成功提交，但字段未重置。我正在使用 Angular Material 进行造型。更新了 Controller 。

 Html

 <form name="myform">
        <md-input-container>
        <label for="name">Contact Name</label>
        <input type="text" md-maxlength="20" required="" md-no-asterisk  name="name" ng-model="info.name" md-autofoucs>
        <div ng-messages="myform.name.$error" role="alert">
      <div ng-message="required">This is required.</div>
      <div ng-message="md-maxlength">The name has to be less than 20 characters long.</div>
      </div>
    </md-input-container>
    <md-input-container>
        <label for="phone">Phone Number</label>
        <input type="text" name="phone" required md-no-asterisk ng-model="info.phone">
        <div ng-messages="myform.phone.$error">
       <div ng-message="required">This is required.</div>
       </div>
    </md-input-container>
    <md-input-container>
        <label for="email">Email</label>
        <input type="text" name="email" ng-model="info.email">
    </md-input-container>
    <md-input-container>
    <md-button class="md-primary" ng-click="saveit(info)">Save</md-button>
    <md-button class="md-primary">Cancel</md-button>
     </md-input-container>

</form>

       var index = $scope.people.indexOf(person);
           $scope.people.splice(index,1);
    }, function() {

<form name="myform">
  <input type="text" ng-model="info.name">
  <input type="text" ng-model="info.phone">
  <input type="text" ng-model="info.email">
</form>

app.controller('MainCtrl', function($scope) {

  $scope.info = {}; // name, phone, email

  $scope.saveit = function() {
    $scope.info.name = ''; // reset name 
    $scope.info.phone= ''; // reset phone
    $scope.info.email= ''; // reset email

    // reset form and disable error messages
    $scope.myform.$setPristine();
    $scope.myform.$setUntouched();
  };

});
