今天学习指令，遇到了一些困惑：

    


    
    
    
    

    
    



    
    

    
        

            Inside p Two : {{aThirdProperty}}
    
            

                Inside p Three:　{{aThirdProperty}}
    
                    

                        Inside p Four:　{{aThirdProperty}}
                        

                        OutSide myDirective: {{myProperty}}
                        

                            Inside myDirective : {{myProperty}}
                        

                    


            


        

    
    

    

js

    var app = angular.module('app', []);
app.controller('someCtrl', ['$scope', function($scope){

    
}])

app.controller('secondCtrl', ['$scope', function($scope){
    console.log($scope.myProperty)    //undefined
    
}])
app.directive('myDirective',function(){
    return {
        restrict :'A',
        scope:false
        
    }

})

为什么打印出来的是undefined？

然后把js指令里的scope改为scope:{};为什么弹出来的是这个？就是说为什么外面的OutSide myDirective: wow! that is cool会有值？

    Inside p Two :
    Inside p Three:　data for 3rd property
    Inside p Four:　data for 3rd property 
    OutSide myDirective: wow! that is cool
    Inside myDirective : wow! that is cool
