ng-model绑定的是ng-option中的什么？ 

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
 <select ng-model="myColor" ng-options="color.name for color in colors">
      <option value="">-- choose color --</option>
    </select>
{{myColor}}
</div>
<script>
angular.module('myApp', [])
  .controller('myCtrl', ['$scope', function($scope) {
    $scope.colors = [
      {name:'black', shade:'dark'},
      {name:'white', shade:'light', notAnOption: true},
      {name:'red', shade:'dark'},
      {name:'blue', shade:'dark', notAnOption: true},
      {name:'yellow', shade:'light', notAnOption: false}
    ];
    $scope.myColor = $scope.colors[2]; // red
  }]);
</script>
</body>
</html>

可见，绑定的是for后边的对象。
