在angular中实现下拉框的两种⽅式ng-repeat和ng-option 1. ng-repeat实现下拉框：

<-option指令使⽤很简单，只需要绑定两个属性：
⼀个是ng-model⽤于获取选定的值；
含鸡的成语另⼀个是ng-options⽤于确定下拉列表的元素数组。
<lect ng-model="engineer.currentActivity" class="form-control" ng-options="act for act in activities"></lect>
上⾯这条语句就是把选择的值与engineer.currentActivity进⾏双向数据绑定，然后列表中的选项是activities中的每⼀个值。数据如下：$ineer = {
name: "Dani",
currentActivity: "Fixing bugs"
};
