本文實例講述了AngularJS實現select的ng-options功能。分享給大家供大家參考，具體如下：

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">發帖</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="標題" 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屬性作為option的value -->      <option value="">選擇主題分類</option>     </select>    </label>    <label class="item item-input myLabel">     <textarea class="post_content" placeholder="內容" ng-model="post.content" required></textarea>    </label>   </div> </ion-content></form></ion-modal-view>

實現的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="">選擇主題分類</option>　　<option value="0" label="主題111">主題111</option>　　<option value="1" label="主題222">主題222</option>　　<option value="2" label="有沒問題">有沒問題</option>　　<option value="3" label="測試112">測試112</option>　　<option value="4" label="你好">你好</option>　　<option value="5" label="主題">主題</option>　　<option value="6" label="測試000">測試000</option></select>

可以用ng-change事件監控來看看輸出的是什么
