Question

如何禁用md-autocomplete中的自由文本？我希望用户只能从项目列表中进行选择,或者如果未从列表中选择项目,则根据某些验证添加ng-message.角度材料md-autocomplete演示

您可以即时将新项目添加到列表中：

<md-autocomplete flex required="required"
                   md-input-name="id"
                   md-selected-item="newItem.item"
                   md-search-text="itemSearch.queryText"
                   md-items="itemin itemSearch.querySearch()"
                   md-item-text="item.name"
                   md-input-minlength="2"
                   md-floating-label="enter here">
    <md-item-template>
                        <span md-highlight-text="itemSearch.queryText"
                md-highlight-flags="^i">{{item.name}}</span>
    </md-item-template>
    <md-not-found>
      Sorry, this is not in our database
    </md-not-found>
    <div ng-messages="formName.id.$error">
      <div ng-message="required">You must enter a name</div>
      <div ng-message="minlength">You must type at least two characters</div>
    </div>
  </md-autocomplete>

编辑：只需将您的消息放入其中即可<md-not-found>
