angularjs的select使用2

https://cnodejs.org/topic/549007b44823a0234c9e1716 

myAppModule.controller('FrmController', ['$scope',function($scope){
 $scope.colors = [{name:'black', shade:'dark'},{name:'white', shade:'light'},{name:'red', shade:'dark'},{name:'blue', shade:'dark'},{name:'yellow', shade:'light'}];
 $scope.myColor = 'red';}]);
<form ng-controller="FrmController">

<select ng-model="m.myColor" ng-options="color.name as color.name for color in colors">

</select>
</form>
----------------------------
$scope.m = $scope.colors[0];
<select ng-model="m" ng-options="***color ***as color.name for color in colors"> 这样居然可以一次获取到 color 对象的全部属性值；


<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>test</title>
<script type="text/javascript" src="angular.min.js"></script>
<script>
var myApp = angular.module("myApp", []);
myApp.controller("testCtrl", function($scope){
    $scope.data = [{id:1,value:'hello'},{id:2,value:'bye'},{id:3,value:'hmmmm'}];
    //$scope.selectValue = $scope.data[0].id;
});
</script>
</head>
 
<body ng-app="myApp">
<form ng-controller="testCtrl">
  <select ng-model="selectValue" ng-options="item.id as item.value for item in data"></select><br /><br />
  <div ng-switch="selectValue">
    <div ng-switch-when="1">hello</div>
    <div ng-switch-when="2">bye</div>
    <div ng-switch-when="3">hmmmm</div>
    <div ng-switch-default>ah?</div>
  </div>
</form>
</body>
</html>
也可以不用switch用ng-show/hide或者ng-if这样的。
