通过Proxy已经拦截属性检索，为何还会判断属性返回true？

Question

let obj = {

            time: '2017-7-20',            name: 'set',            _r: 123
        };

let daili = new Proxy(obj,{

                has(target,key){                if (key==='name'){                    return target[key];
                }else{                    return false;
                }
            }
        });

console.log('name' in obj,'time' in obj); //true true 后面的应该是false啊

Answer 1

console.log('name' in daili,'time' in daili);
