Angular Material md-select没有显示错误

Question

我正在尝试实现一个表单,其中错误消息在单击提交按钮之前不会显示.对于输入,这似乎是开箱即用的,但对于md-select不符合预期.

当我提交表单(没有填写任何内容)时,我收到输入的错误消息,但不是md-select的错误消息.

这是表格:

<form name="userForm" novalidate ng-submit="test()">
  <md-input-container>
    <label>Last Name</label>
    <input name="lastName" ng-model="lastName" required>
    <div ng-messages="userForm.lastName.$error">
      <div ng-message='required'>This is required!</div>
    </div>
  </md-input-container>

  <md-input-container class="md-block">
    <label>Favorite Number</label>
    <md-select name="favoriteNumber" ng-model="myNumber" required>
      <md-option value="1">One</md-option>
      <md-option value="2">Two</md-option>
    </md-select>
    <div ng-messages="userForm.favoriteNumber.$error">
      <div ng-message='required'>This is required</div>
    </div>
  </md-input-container>

  <div>name = {{lastName}}</div>
  <div>userForm.lastName.$error = {{userForm.lastName.$error}}</div>
  <div>number = {{myNumber}}</div>
  <div>userForm.favoriteNumber.$error = {{userForm.favoriteNumber.$error}}  </div>

  <md-button type="submit" class="md-raised md-primary">Save</md-button>
</form>

请注意,这是从Angular Material 1.1.1开始修复的

也许这可以帮助:

<div ng-messages="userForm.favoriteNumber.$error" ng-show="userForm.favoriteNumber.$invalid">
