To add private variable to this Javascript literal object

2024-09-27 15:22:01

You can use number as function/variable name, the numberic name can't be accessed from parent scope, but can be accessed by 'this' in private scope.

var o=

    {

      attr1:'value of attr1',

       1:'private attr ,the index is 1',

       301:function(){

         console.log('private function , name is 2');

       },

       fun1:function(){

        console.log(this[1]);

         this[301].call(this);

      }

    };

o.fun1();
