1 //优化前 2 function Person (name,age){ 3 this.name=name; 4 this.age=age; 5 this.run=function () { 6 console.log('pao'); 7 } 8 } 9 var p=new Person('sz',18); 10 var p2=new Person('zs',19); 11 console.log(p.run == p2.run);//返回false 12 //优化后 13 var runfuctin=function () { 14 console.log('pao'); 15 } 16 17 function Person (name,age){ 18 this.name=name; 19 this.age=age; 20 this.run=runfuctin; 21 } 22 var p=new Person('sz',18); 23 var p2=new Person('zs',19); 24 console.log(p.run == p2.run);//返回true
