我有一个非常大的形式,由Angular在客户端验证。我试图找出如何重置窗体的状态及其输入只需单击重置按钮。

我在表单上尝试了$setPristine(),但它并没有真正起作用,这意味着它不会清除ng-*类,无需执行验证即可将表单重置为原始状态。< / p>

这是我的表单的简短版本:

<form id="create" name="create" ng-submit="submitCreateForm()" class="form-horizontal" novalidate>
    <div class="form-group">
        <label for="name" class="col-md-3 control-label">Name</label>
        <div class="col-md-9">
            <input required type="text" ng-model="project.name" name="name" class="form-control">
            <div ng-show="create.$submitted || create.name.$touched">
                <span class="help-block" ng-show="create.name.$error.required">Name is required</span>
            </div>  
        </div>
    </div>
    <div class="form-group">
        <label for="lastName" class="col-md-3 control-label">Last name</label>
        <div class="col-md-9">
            <input required type="text" ng-model="project.lastName" name="lastName" class="form-control">
            <div ng-show="create.$submitted || create.lastName.$touched">
                <span class="help-block" ng-show="create.lastName.$error.required">Last name is required</span>
            </div>
        </div>
    </div>
    <button type="button" class="btn btn-default" ng-click="resetProject()">Reset</button>
</form>

我的重置功能:

$scope.resetProject = function() {
    $scope.project = {
        state: "finished",
        topic: "Home automation"
    };
    $("#create input[type='email']").val('');
    $("#create input[type='date']").val('');
    $scope.selectedState = $scope.project.state;
    // $scope.create.$setPristine(); // doesn't work
}

另外,如果你可以帮我清除电子邮件和日期字段的输入值而不使用jQuery会很棒。因为将$scope.project设置为上面定义的内容不会因某种原因重置字段。

尝试通过ng-model清除

$scope.resetProject = function() {
  $scope.project = {
      state: "finished",
      topic: "Home automation"
  };
  $("#create input[type='email']").val('');
  $("#create input[type='date']").val('');
  $scope.selectedState = $scope.project.state;

  $scope.project = {
      name: "",
      lastName: ""
  };
}

如评论中所述,您可以使用$setUntouched();

https://docs.angularjs.org/api/ng/type/form.FormController# $ setUntouched

这应该将表格设置回它的新状态。

所以在这种情况下$scope.create.$setUntouched();应该做的伎俩

参考所有jquery。您永远不应该通过控制器与DOM交互。

的指令是什么

如果要重置给定的属性,请执行以下操作:

$scope.resetProject = function() {
    $scope.project = {
        state: "finished",
        topic: "Home automation"
    };
    $scope.project.lastName = '';
   $scope.project.date= '';
}
