<div ng-app="myApp" ng-controller="myCtrl"> <select ng-model="selectedName" ng-options="x for x in names"></select> 等价于： <select> <option ng-repeat="item in names">{{item}}</option> </select> <hr> <!-- ng-repeat绑定的值为一个字符串，ng-options绑定的为一个对象 --> <select ng-model="selectedSIte"> <option ng-repeat="item in sites" value="{{item.url}}">{{item.site}}</option> </select> <span>你选中的选址：{{selectedSIte}}</span> <br><br> <select ng-model="selectedSite" ng-options="x.site for x in sites"></select> <span>你选中的选址：{{selectedSite}}</span> <hr> <!-- 因为对象数组没有key，angular默认使用数组的下标值作为key显示 --> <select ng-model="AAAA" ng-options="x for (x, y) in sites"></select> <span>你选择的值是: {{AAAA}}</span> </div>
