AngularJS实现select的ng-options功能示例

2017年12月12日  | 移动技术网IT编程  | 我要评论

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
