我在控制器中验证了一个电子邮件地址。当出现错误时,我想显示错误消息......
在这种情况下,用户输入: myname @ email (无效)
验证工作正常,我的范围如下:
Object {
email_used: false,
email_invalid: true,
email_required: false
}
在我的模板中,输入字段上的错误类正常工作:
<input type="email" name="email" placeholder="E-mailadres" ng-model="new_user.email" class="grid-100" ng-class="(error_register.email_used || error_register.email_invalid || error_register.email_required) ? 'error' : ''"/>
...但是我的错误消息没有显示?
<!-- ERRORS -->
<span class="ngdialog-form-error" ng-if="error_register.email_used" ng-cloak>Email is used<span>
<span class="ngdialog-form-error" ng-if="error_register.email_required" ng-cloak>Email required<span>
<span class="ngdialog-form-error" ng-if="error_register.email_invalid" ng-cloak>Email invalid<span>

您尚未关闭span标记。
var app = angular.module("app", []);
app.controller("controller", function($scope) {
$scope.error_register = {
email_used: false,
email_invalid: true,
email_required: false
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<div ng-app="app" ng-controller="controller">
<span class="ngdialog-form-error" ng-if="error_register.email_used" ng-cloak>Email is used</span>
<span class="ngdialog-form-error" ng-if="error_register.email_required" ng-cloak>Email required</span>
<span class="ngdialog-form-error" ng-if="error_register.email_invalid" ng-cloak>Email invalid</span>
</div>
