<h2>1.使用 ng-options 指令</h2>
<!--ng-options 指令创建的下拉列表,选中的值是一个对象, 所以建议使用 ng-option来创建select -->
<p>选择水果:</p>
<!-- ng-model 和 ng-init 里面绑定的变量名需要一样 -->
<select ng-model="selectedFruit" ng-init="selectedFruit= fruits[1]" ng-options="x.Alias for x in fruits">
</select>
<p>你选择的是: {{selectedFruit.name}}</p>
<p>别名为: {{selectedFruit.Alias}}</p>
<p>单价为: {{selectedFruit.price}}</p>
<h2>2.使用 ng-repeat 指令</h2>
<!-- ng-repeat 指令创建的下拉列表,选中的值是一个值。 -->
<p>选择水果:</p>
<select ng-model="selectedFruit2" ng-init="selectedFruit2= fruits[1].name">
<option ng-repeat="x in fruits" value="{{x.name}}">{{x.Alias}}</option>
</select>
<p>你选择的是: {{selectedFruit2}}</p>
<h2>3.数据源为对象</h2>
<p>选择水果:</p>
<select ng-model="selectedFruit3" ng-init="selectedFruit3= fruits3.fruit1" ng-options="x for (x,y) in fruits3">
</select>
<select ng-model="selectedFruit3" ng-init="selectedFruit3= fruits3['fruit1']" ng-options="x for (x,y) in fruits3">
</select>
<p>你选择的是: {{selectedFruit3.name}}</p>
<p>别名为: {{selectedFruit3.Alias}}</p>
<p>单价为: {{selectedFruit3.price}}</p>
<p>或者</p>
<p>选择水果:</p>
<select ng-model="selectedFruit4" ng-options="y.Alias for (x,y) in fruits3">
</select>
<p>你选择的是: {{selectedFruit4.name}}</p>
<p>别名为: {{selectedFruit4.Alias}}</p>
<p>单价为: {{selectedFruit4.price}}</p>
