本文实例讲述了AngularJS实现select的ng-options功能。分享给大家供大家参考，具体如下：

controller

.controller('MainController', function($scope, $http, $ionicModal, $timeout) {
 var post = {};
 $http.get("data/themeData.json")
 .success(function(response) {
 $scope.themeData = response.themeData;
 });
 $ionicModal.fromTemplateUrl('templates/post.html', {
 scope: $scope
 }).then(function(modal) {
 $scope.modal = modal;
 });
 $scope.postShow = function() {
 post = $scope.post = {};
 $scope.modal.show();
 };
 $scope.cancelPost = function() {
 $scope.modal.hide();
 };
 $scope.doPost = function() {
 console.log('doPost-----');
 console.log(post);
 $timeout(function() {
 $scope.cancelPost();
 }, 1000);
 };
 })

html

<ion-modal-view>
<form name="post_form">
 <ion-header-bar>
 <button class="button button-icon icon ion-ios-arrow-back" ng-click="cancelPost()"></button>
 <h1 class="title">发帖</h1>
 <button class="button button-icon icon ion-forward" ng-disabled="post_form.$invalid" ng-click="doPost()"></button>
 </ion-header-bar>
 <ion-content>
 <div class="list">
 <label class="item item-input myLabel">
 <input type="text" placeholder="标题" ng-model="post.title" required/>
 </label>
 <label class="item item-input myLabel2">
 <select class="mySelect col" ng-model="post.kmForumCategoryId" ng-options="theme.id as theme.name for theme in themeData" required>
　　　　<!-- 添加了id属性作为option的value -->
 <option value="">选择主题分类</option>
 </select>
 </label>
 <label class="item item-input myLabel">
 <textarea class="post_content" placeholder="内容" ng-model="post.content" required></textarea>
 </label>
 </div>
 </ion-content>
</form>
</ion-modal-view>

实现的DOM

<select class="mySelect col ng-pristine ng-untouched ng-invalid ng-invalid-required" ng-model="post.kmForumCategoryId" ng-options="theme.id as theme.name for theme in themeData" required="">
　　<option value="">选择主题分类</option>
　　<option value="0" label="主题111">主题111</option>
　　<option value="1" label="主题222">主题222</option>
　　<option value="2" label="有没问题">有没问题</option>
　　<option value="3" label="测试112">测试112</option>
　　<option value="4" label="你好">你好</option>
　　<option value="5" label="主题">主题</option>
　　<option value="6" label="测试000">测试000</option>
</select>

可以用ng-change事件监控来看看输出的是什么
