AngularJS中下拉框的基本用法示例

<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>

var app = angular.module('myApp', []);app.controller('myCtrl', function($scope) {$scope.names = ["Google", "Baidu", "Taobao"];$scope.sites = [{ site : "Google", url : "http://www.google.com"},{site : "Baidu", url : "http://www.baidu.com"},{site : "Taobao", url : "http://www.taobao.com"} ];});
