Question

我有一个预定义的模型，我正在使用md-select（selectedVegetables）。当它的模型已经具有键和值时，它似乎不适用于我的模型。Code Pen

检查：

$scope.vegetables = 
    [{"key":"1","value":"Banana"},{"key":"2","value":"Apple"}];
$scope.selectedVegetables = [{"key":"1","value":"Apple"}];

在我的控制器中。

和我的HTML

   <md-input-container>
    <label>Vegetables</label>
    <md-select ng-model="selectedVegetables" md-on-close="clearSearchTerm()" data-md-container-class="selectdemoSelectHeader" multiple="">
      <md-select-header class="demo-select-header">
        <input ng-model="searchTerm" placeholder="Search for a vegetable.." class="demo-header-searchbox md-text" type="search">
      </md-select-header>
      <md-optgroup label="vegetables">
        <md-option ng-value="vegetable" ng-repeat="vegetable in vegetables |
          filter:searchTerm">{{vegetable}}</md-option>
      </md-optgroup>
    </md-select>
  </md-input-container>

Answer 1

我找到了解决方案。解决方案是将其添加到md-select

ng-model-options="{trackBy: '$value.key'}"

md-select不从键值param的模型更新
