AngularJS 1.5.6重置表& NG的消息 [英] AngularJS 1.5.6 reset form & ng-messages

问题描述

我读了一些Stackoverflow帖子如何重置表单，但我没有得到它。
输入有效但显示错误消息。调试应用程序向我显示消息得到样式=不透明度：1; margin-top：0px;，但我不知道从哪里开始。

I read some Stackoverflow posts how to reset a form, but I doesn't get it. The input was valid but the error message was shown. Debugging the application shows me that the message gets a style="opacity: 1;margin-top: 0px;", but I have no idea from where.

<md-input-container flex style="margin-top: 0;margin-bottom: 5px">
    <label translate>maintenanceMessage.description</label>
    <input md-maxlength="40" required name="description" md-no-asterisk
           ng-model="maintenanceMessageCtrl.newMaintenanceMessage.description" flex>
    <div ng-messages="maintenanceMessageForm.description.$error" ng-if="maintenanceMessageForm.description.$touched">
      <div ng-message="required" translate>maintenanceMessage.description.requiredMessage</div>
      <div ng-message="md-maxlength" translate>maintenanceMessage.description.maxLengthMessage</div>
    </div>
  </md-input-container>

复位时执行以下功能

  ctrl.resetFormAndHideDialog = function () {
  ctrl.newMaintenanceMessage = {};
  ctrl.newMaintenanceMessage.expirationDate = new Date();
  ctrl.showLastModification = false;
  $scope.maintenanceMessageForm.$setUntouched();
  $scope.maintenanceMessageForm.$setPristine();
  $mdDialog.hide();
};

我错过了什么吗？

谢谢帮助。

Conclusio ：
似乎角料1.1.1有一个bug 。所以ng-message没有被隐藏。

Conclusio: It seems that angular material 1.1.1 has a bug. So ng-message wasn't hidden.

我已将相关的标记和代码放入CodePen中，看起来很好 - CodePen

I've put your relevant markup and code into a CodePen and it seems fine - CodePen

唯一奇怪的是表单重置时字符数不会设置为0。 可能是个错误。

The only odd thing is that the character count does not get set to 0 on form reset. Maybe a bug.

<div ng-controller="AppCtrl" ng-cloak="" ng-app="MyApp">
   <form name="maintenanceMessageForm">
    <md-input-container flex style="margin-top: 0;margin-bottom: 5px">
      <label>maintenanceMessage.description</label>
      <input md-maxlength="40" required name="description" md-no-asterisk ng-model="newMaintenanceMessage.description" flex>
      <div ng-messages="maintenanceMessageForm.description.$error" ng-if="maintenanceMessageForm.description.$touched">
        <div ng-message="required">{{maintenanceMessage.description.requiredMessage}}</div>
        <div ng-message="md-maxlength">{{maintenanceMessage.description.maxLengthMessage</div>
      </div>
    </md-input-container>
  </form>
  <md-button class="md-raised md-primary" ng-click="resetForm()">Reset</md-button>
</div>

JS

angular.module('MyApp',['ngMaterial', 'ngMessages', 'material.svgAssetsCache', 'ngDialog'])

.controller('AppCtrl', function($scope) {
  $scope.maintenanceMessage = {
    description: {
      requiredMessage: "This is required",
      maxLengthMessage: "Max length is 40"
    }
  };

  $scope.resetForm = function () {
    $scope.newMaintenanceMessage = {};
    $scope.maintenanceMessageForm.$setUntouched();
    $scope.maintenanceMessageForm.$setPristine();
  };
});
