Angular,ng-messages未在角度材料设计对话框中显示(md-dialog)

Question

我正在使用一个表格在angularJS中添加信用卡,使用角度材料(https://material.angularjs.org/latest/#/).

对于我所有的其他形式,我使用ng-messages(https://docs.angularjs.org/api/ngMessages/directive/ngMessages)来显示验证错误,并且它工作正常.

当我在md对话框中嵌入表单时,我的ng-messages没有显示,输入变为无效,但没有显示错误.我遇到了基本验证指令和自定义验证指令的问题.

我的对话框模板:

<md-dialog>
<md-dialog-content style="max-width:800px;max-height:810px; ">
    <h2 i18n="add_card_button"></h2>
    <form name="form">
        <md-input-container>
            <label i18n="card_number"></label>
            <input  name="card_number"
                    type="text" 
                    ng-model="ctrl.newCard.cc_number"
                    class="md-input" 
                    required
                    card-number>
            <div ng-messages="form.card_number.$error">
                <div ng-message="cardNumber">test message</div>
                <div ng-message="required">test message 2</div>
            </div>
        </md-input-container>
        ...
    </form>
</md-dialog-content>
<div class="md-actions" layout="row">           
    <md-button ng-click="">
        <i18n>ok_button</i18n>
    </md-button>
    <md-button ng-click="cancel()" style="margin-right:20px;">
        <i18n>cancel_button</i18n>
    </md-button>
</div>

我的对话框定义:

$mdDialog.show({
            controller : dialogController,
            controllerAs : "ctrl",
            bindToController : true,
            templateUrl : "creditCards/assets/templates/add_credit_card_dialog.html",
            parent : angular.element(document.body),
            targetEvent : event,
            clickOutsiteToClose : true,
            locals : {
                cardTypes : vm.cardTypes
            }
        });

和我的自定义指令定义

angular
    .module('app.core')
    .directive("cardNumber", cardNumber);

/* @ngInject */
function cardNumber () {
    var directive = {
        link: link,
        restrict: 'A',
        require : "ngModel"
    };
    return directive;

    function link(scope, element, attrs, ngModel) {
        ngModel.$validators.cardNumber = cardNumber;

        scope.$watch("cardNumber", function(){
            ngModel.$validate();
        });

        // Validate visa, mastercard, amex, concate new regex to validate more card
        var reg = new RegExp(/^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|3[47][0-9]{13})$/);

        function cardNumber(modelValue){
            if(!modelValue){
                return true;
            }

            modelValue = modelValue
                            .replace(/-/g, "")
                            .replace(/\s/g, "")
                            .replace(/,/g, "");

            return reg.test(modelValue);
        }
    }
}

以及结果的屏幕截图,您可以在其中看到无效字段但没有错误消息:

Answer 1

这里有两个可能的修复:https://github.com/angular/material/issues/8037

1. 确保ng-app指令位于页面的body标签上.

2. parent: angular.element(document.body)从$ mdDialog.show()选项中删除该行.

Answer 2

我能够完成这项工作。

1. 将 Angular Messages 添加到凉亭和索引
2. 将模块 ngMessages 添加到您的应用程序
3. 在 md-input-container 上执行此操作

<md-input-container flex md-is-error="signupForm.emailAddress.$invalid && (signupForm.$submitted || signupForm.emailAddress.$dirty)">
  <label>Email Addresss</label>
  <input name="emailAddress" ng-model="registerInfo.emailAddress" type="email" required/>
  <div ng-messages="signupForm.emailAddress.$error" ng-if='signupForm.$submitted || signupForm.emailAddress.$touched'>
    <div ng-message="required">This is required.</div>
    <div ng-message="email">Enter valid email address.</div>
  </div>
</md-input-container>

对于自定义指令我这样做了

<div ng-messages="signupForm.verify.$error" ng-if='signupForm.verify.$dirty || signupForm.verify.$touched'>
  <div ng-message="required">This is required.</div>
  <div ng-message="passwordVerify">Doesn't Match.</div>
</div>
