如何通过ng-bind绑定变量

html代码：

    

        

            

            初始值
        
        
{{cdkey.name}}
        
            {{cdkey.name}}
        
            

            

            

            初始值
        
        
{{cdkey.key}}
        
            {{cdkey.key}}
        
    

js代码

angular.module("MyApp", [])
.controller("MyController", ["$scope", function($scope){
    $scope.cdkey = {
        name: {
            hello: "Hello, World"
        },
        key: "hello"
    }
}])
