Question

我正在尝试从md-autcomplete触发ng-enter事件。目的是当我在自动完成下拉菜单项上使用键盘时，应调用一个函数。这是html代码

<body layout="column">
  <div ng-app="chipsCustomInputDemo" ng-controller="CustomInputDemoCtrl" layout="column">
    <md-content layout-padding class="autocomplete" layout="column">
      <form>
        <md-autocomplete id='Auto'
                         md-min-length="1"
                         ng-enter="presEnter();"
                         md-no-cache="true"                        
                         md-selected-item="selectedItem" 
                         md-search-text="searchText" 
                         md-items="item in querySearch(searchText)"
                         md-item-text="item.name" 
                         placeholder="Search for a vegetable">
          <span md-highlight-text="searchText">{{item.name}} :: {{item.type}}</span>
        </md-autocomplete>
        <md-item-template>
          <span ng-enter="sayHi()">
          <strong>{{item.name}}</strong>

        </span>
        </md-item-template>
      </form>
      <br />

      <div class="md-2-line" ng-repeat="veg in vegetables">
        <h3>{{veg.name}}</h3>
        <p>{{veg.type}}</p>
        <hr />
      </div>
    </md-content>
