AngularJS中下拉框的高级用法示例

Zerone1993 人气:0

本文实例讲述了AngularJS中下拉框的高级用法。分享给大家供大家参考,具体如下:

HTML正文:

<body ng-app="myApp">
<!-- 对象内部属性遍历:x--key y---value -->
<div ng-controller="myctr01">
{{sites}}<br>
<select ng-model="site" ng-options="x for (x, y) in sites"></select>
选择的网址:<span>{{site}}</span>
</div>
<div ng-controller="myCtrl">
<p>选择一辆车:</p>
<!-- 这里y标识成员元素对象,并且使用该对象的brand属性作为显示文本,select的值与y绑定 -->
<select ng-model="selectedCar" ng-options="y.brand for (x, y) in cars"></select>
<p>你选择的是: {{selectedCar.brand}}</p>
<p>型号为: {{selectedCar.model}}</p>
<p>颜色为: {{selectedCar.color}}</p>
<p>下拉列表中的选项也可以是对象的属性。</p>
</div>

Javascript操作代码:

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  //复杂对象
  $scope.cars = {
  car01 : {brand : "Ford", model : "Mustang", color : "red"},
  car02 : {brand : "Fiat", model : "500", color : "white"},
  car03 : {brand : "Volvo", model : "XC90", color : "black"} }
  //简单对象
  $scope.sites = {
      site01 : "Google",
      site02 : "Baidu",
      site03 : "Taobao"
   };
});
app.controller("myctr01",function($scope){
  $scope.sites = {
      site01 : "Google",
      site02 : "Baidu",
      site03 : "Taobao"
  };
});

效果:

希望本文所述对大家AngularJS程序设计有所帮助。
