Question

我正在尝试构建一个使用角度材质的页面，并使用md-chips和md-autocomplete等元素。

我想对此md-chips进行验证，以便在没有筹码且点击提交按钮时会显示错误消息，类似于md-input-container。

对于md-input-container我的代码如下

<md-input-container class="md-block" flex-gt-sm>
      <label>Title</label>
      <input md-maxlength="100" maxlength="100" required type="text" name="bookTitle" ng-model="bookCtrl.book.name">

      <div ng-messages="bookForm.bookTitle.$error" role="alert">
        <div ng-message-exp="['required', 'maxlength']">
          Book title is required and it should not exceed 100 characters.
        </div>
      </div>
    </md-input-container>

如果不符合验证，则会出现警告。如何执行与md-chips md-autocomplete类似的具有以下代码

的内容

<md-chips name="bookAuthors" ng-model="bookCtrl.book.authors" md-autocomplete-snap
              md-separator-keys="bookCtrl.keys"
              md-transform-chip="bookCtrl.transformChip($chip)"
              md-require-match="bookCtrl.authorAutocompleteRequireMatch">
      <md-autocomplete
        md-selected-item="bookCtrl.selectedAuthor"
        md-search-text="bookCtrl.searchAuthor"
        md-items="author in bookCtrl.querySearch(bookCtrl.searchAuthor, bookCtrl.bookAuthors)"
        md-item-text="author.name"
        placeholder="Author">
        <span md-highlight-text="bookCtrl.searchAuthor">{{author.name}}</span>
      </md-autocomplete>

      <md-chip-template>
        <span>{{$chip.name}}</span>
      </md-chip-template>
    </md-chips>

可以添加到md-chips以执行验证？

Answer 1

在md-chips块之外创建div块并添加红色。它将类似地工作

<div ng-messages="{test:true}" ng-show="true">
    <div ng-message="test" style="color: rgb(221,44,0); font-size:12px">errroro123</div>
</div>

使用md-autocomplete验证md-chips
