【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
