本文实例讲述了AngularJS中下拉框的高级用法。分享给大家供大家参考，具体如下：

HTML正文：

<body ng-app="myApp"><!-- 对象内部属性遍历：x--key y---value --><div ng-controller="myctr01">{{sites}}<br><select ng-model="site" ng-options="x for (x, y) in sites"></select>选择的网址：<span>{{site}}</span></div><div ng-controller="myCtrl"><p>选择一辆车:</p><!-- 这里y标识成员元素对象，并且使用该对象的brand属性作为显示文本,select的值与y绑定 --><select ng-model="selectedCar" ng-options="y.brand for (x, y) in cars"></select><p>你选择的是: {{selectedCar.brand}}</p><p>型号为: {{selectedCar.model}}</p><p>颜色为: {{selectedCar.color}}</p><p>下拉列表中的选项也可以是对象的属性。</p></div>

Javascript操作代码：

var app = angular.module('myApp', []);app.controller('myCtrl', function($scope) {  //复杂对象  $scope.cars = {  car01 : {brand : "Ford", model : "Mustang", color : "red"},  car02 : {brand : "Fiat", model : "500", color : "white"},  car03 : {brand : "Volvo", model : "XC90", color : "black"} }  //简单对象  $scope.sites = {      site01 : "Google",      site02 : "Baidu",      site03 : "Taobao"   };});app.controller("myctr01",function($scope){  $scope.sites = {      site01 : "Google",      site02 : "Baidu",      site03 : "Taobao"  };});

效果：
