【AngularJs】---实现select的ng-options

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
