</html>在 Plunkr 中添加:https://plnkr.co/edit/1LgFCNqT0YDkyUAaC31C以及上面提供的代码片段。
上面的页面代码片段描述了一些问题。
描述:指令 people-pickcer当我们在 md-autocomplete 中搜索时会引入用户标签，当选择某些内容时，它会转换为 md-chip 并添加到父项 md-chips 中。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，则每当因无效输入而模糊时都会引发错误。我尝试写一个 $validators对于我的模块，但它永远不会触发，当我删除任何 md 芯片时，它也会触发所有验证(我认为它在删除任何芯片时尝试提交表单)。尝试在不触摸标题输入框的情况下删除 md-chip，您将看到标题验证器被触发，如果有更多带有验证的输入字段，如果我从选择中删除任何 md-chip，所有验证器都会被触发。
required来 self 的模块的指令
angular.module('peoplePickerCombo')
.directive('required', function() {
return {
restrict: "A",
require: 'ngModel',
link: function(scope, element, attrs, ctrl) {
if (!ctrl) {
return false;
}
ctrl.$validators.required = function(modelValue,viewValue) {
//console.log(modelValue , viewValue)
return !!( modelValue && modelValue.length>0 );
};
}
}
});
预计当所有 md-chips 被移除时它应该抛出一个错误，但它从未抛出任何错误。
最佳答案
让我们将人员选择器组合的 required 指令重命名为 ppcRequired，否则它将应用于任何其他必需的输入。人员选择器看起来像
<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>由于模型更改 ( https://github.com/angular/material/issues/8126 ) 时未运行所需的验证器，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，但它们仍然未受影响，因此我们添加 CSS 类 md-touched，仅当字段被触摸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, people-picker.ng-invalid-required md-input-container.md-input-focused label { color: rgb(221, 44, 0); } md-input-container.md-input-invalid label.md-required::after, md-input-container.md-input-focused label.md-required::after, md-input-container.md-input-has-value label.md-required::after, md-input-container.md-input-invalid label.md-required { color: rgba(0, 0, 0, 0.54); } 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; color: rgb(221, 44, 0); } [ppc-required] md-input-container label::after { content: " *"; font-size: 13px; vertical-align: top; }
