</html>在 Plunkr 中添加：https ://plnkr.co/edit/1LgFCNqT0YDkyUAaC31C和上面提供的代码片段。
上面的页面代码段中描述了一些问题。
描述：指令people-pickcer在我们在标签中搜索时带来了用户，md-autocomplete并且在选择某些内容时会转换为MD-Chip并将其添加到父母中md-chips。当所有芯片都被移除时，它应该抛出验证错误<div ng-message="required">User is required</div>。
用法：
<div>
<people-picker
required name="user" ng-disabled="false" service="ctrl.userLookupService"
max-chips="5" placeholder="User" secondary-placeholder="Add Another?"
ng-model="ctrl.users" aria-label="Users"></people-picker>
<div ng-messages="pForm.user.$error" class="customMessages">
<div ng-message="required">User is required</div>
<div ng-message="resolve">One or more users have not been resolved</div>
</div>
</div>
问题：
如果您看到“标题”输入框，只要输入无效，就会引发错误。我尝试为我的模块编写一个$validators但它永远不会触发，当我删除任何 md-chip 时它也会触发所有验证（我认为它会在删除任何芯片时尝试提交表单）。尝试在不触摸 Title 输入框的情况下删除 md-chip，您将看到验证器已为 Title 触发，如果我从选择中删除任何 md-chip，则如果有更多带有验证的输入字段将全部触发。
required来自我的模块的指令
angular.module('peoplePickerCombo')
.directive('required', function() {
return {
restrict: "A",
require: 'ngModel',
link: function(scope, element, attrs, ctrl) {
if (!ctrl) {
return false;
}
ctrl.$validators.required = function(modelValue,viewValue) {
//console.log(modelValue , viewValue)
return !!( modelValue && modelValue.length>0 );
};
}
}
});
预计在移除所有 md 芯片时它应该会引发错误，但它永远不会引发任何错误。
