AngularJS学习笔记(二)

一.AngularJS Select(选择框)

1.使用 ng-options 创建选择框 

 
 

  
  <div ng-app="myApp" ng-controller="myCtrl">
 
 
   <select ng-init="selectedName = names[0]" ng-model="selectedName" ng-options="x for x in names"> </select>
</div>
<script>
   var app = angular.module('myApp', []);
   app.controller('myCtrl', function($scope) {
       $scope.names = ["Google", "Runoob", "Taobao"];
   });
</script>

 2.使用 ng-repeat 指令来创建下拉列表

 
 

  
  <div ng-app="myApp" ng-controller="myCtrl">
 
 
  <select> <option ng-repeat="x in names">{{x}}</option> </select>
</div>
<script>
   var app = angular.module('myApp', []);
   app.controller('myCtrl', function($scope) {
       $scope.names = ["Google", "Runoob", "Taobao"];
   }); 
</script>

3. 使用了数组作为数据源:   x  为键(key),  y  为值(value)

 
 

  
  <div ng-app="myApp" ng-controller="myCtrl">
 
 
   <p>选择一辆车:</p>
   <select ng-model="selectedCar" ng-options="x for (x, y) in cars"> </select>
   <h1>你选择的是: {{selectedCar.brand}}</h1>
   <h2>模型: {{selectedCar.model}}</h2>
   <h3>颜色: {{selectedCar.color}}</h3>
   <p>注意选中的值是一个对象。</p>
</div>
<script>
  var app = angular.module('myApp', []);
  app.controller('myCtrl', function($scope) {
     $scope.cars = {
         car01 : {brand : "Ford", model : "Mustang", color : "red"},
         car02 : {brand : "Fiat", model : "500", color : "white"},
         car03 : {brand : "Volvo", model : "XC90", color : "black"}
     } });
</script>
