在Plunkr中添加：https://plnkr.co/edit/1LgFCNqT0YDkyUAaC31C和上面提供的代码段。
上面的页面代码段中描述了一些问题。
说明：当我们在people-pickcer标签中搜索时，指令md-autocomplete会引入用户，当选择某些内容时，它会转换为md-chip并添加到父md-chips。当所有芯片被移除时，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.$error" class="customMessages">
<div ng-message="required">User is required</div>
<div ng-message="resolve">One or more users have not been resolved</div>
</div>
</div>
问题：
如果您看到标题输入框，则无论何时模糊，输入无效都会引发错误。我尝试为我的模块编写$validators，但它永远不会触发，当我删除任何md-chip时它会触发所有验证（我认为它会在删除任何芯片时尝试提交表单）。尝试在不触摸标题输入框的情况下删除md-chip，您将看到为标题触发验证器，如果有更多输入字段进行验证，如果我从选择中移除任何md-chip，则会触发所有输入。
required指令
angular.module('peoplePickerCombo')
.directive('required', function() {
return {
restrict: "A",
require: 'ngModel',
link: function(scope, element, attrs, ctrl) {
if (!ctrl) {
return false;
}
ctrl.$validators.required = function(modelValue,viewValue) {
//console.log(modelValue , viewValue)
return !!( modelValue && modelValue.length>0 );
};
}
}
});
预计在删除所有md-chips后应该抛出错误，但它不会抛出任何错误。
答案 0 :(得分：1)
这是因为指令变异数组，而值（数组）永远不会改变。
例如，您可以在指令中添加以下$ watch：
-y -i inputPath -vf scale=640:480,setsar=1,transpose=1 -strict experimental -r 25 -vcodec mpeg4 -b 1000k ab 48000 -ac 2 -ar 22050 destinationPath
答案 1 :(得分：1)
让我们将必需的指令重命名为 ppcRequired 的人员选择器组合，否则它将应用于任何其他所需的输入。人物选择器看起来像
<people-picker ppc-required
name="user"
service="ctrl.userLookupService"
max-chips="10"
placeholder="User"
secondary-placeholder="Add Another?"
ng-model="ctrl.users"
aria-label="Users"></people-picker>
<div ng-messages="(pForm.$submitted || pForm.user.$touched) && 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>
由于未在模型更改（https://github.com/angular/material/issues/8126）上运行所需的验证程序，因此我们使用 $ watch 来触发所需的更改：
angular.module('peoplePickerCombo').directive('ppcRequired', function() {
return {
restrict: "A",
require: 'ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
if (!ngModelCtrl) {
return false;
}
// override $isEmpty function
ngModelCtrl.$isEmpty = function (val) {
return !val || !val.length;
};
// add required validator
ngModelCtrl.$validators.required = function(modelValue) {
return !ngModelCtrl.$isEmpty(modelValue);
};
// watch for changes
scope.$watch(attrs.ngModel, function (nVal, oVal) {
if (nVal && nVal !== oVal) {
// run validations
ngModelCtrl.$$runValidators(nVal, oVal, function () {});
// update css classes
ngModelCtrl.$setTouched();
ngModelCtrl.$$updateEmptyClasses(nVal);
}
}, 1);
}
}
});
另外2个标题输入被 MD 标记为无效，但它们仍未被触及，因此我们添加了md-touching的CSS类，只有在触摸字段或表单时才会出现提交：
<md-input-container class="md-block"
ng-class="{'md-touched': pForm.title.$touched || pForm.$submitted}"
flex>
<input type="text"
placeholder="Title"
aria-label="Title"
required
name="title"
ng-model="ctrl.Title">
<div ng-messages="(pForm.$submitted || pForm.title.$touched) && pForm.title.$error">
<div ng-message="required">Title is required</div>
</div>
</md-input-container>
添加一些CSS：
md-input-container.md-touched.md-input-invalid label.md-required::after,
md-input-container.md-touched.md-input-invalid label.md-required,
people-picker.ng-invalid-required md-input-container label,

}
md-input-container.md-input-invalid label.md-required::after,

}
md-input-container.md-touched.md-input-invalid .md-input {
border-color: rgb(221, 44, 0);
}
md-input-container.md-input-invalid .md-input {
border-color: rgba(0, 0, 0, 0.12);
}
people-picker.ng-invalid-required md-chips .md-chips {
box-shadow: 0 1px rgb(221, 44, 0);
}
people-picker + .customMessages [ng-message] {
font-size: 12px;
line-height: 14px;
margin-top: 0;
opacity: 1;
overflow: hidden;
padding-top: 5px;
transition: all 0.3s cubic-bezier(0.55, 0, 0.55, 0.2) 0s;

}
[ppc-required] md-input-container label::after {

font-size: 13px;
vertical-align: top;
}
