js对象的创建和函数

创建对象

            var obj1 = {
                name:'老八',
                age:'30'
            }
            console.log(obj1.age)
            console.log(obj1.name)  //输出name
            console.log(obj1)  //输出整个对象里的东西

工厂模式

                let obj = new Object()
                obj.name = name;
                obj.age = age;
                obj.sty = function(){
                    console.log('wdnmd')    
                }
                return obj      //返回到show
            }
            var l1 = show('我带你们打',15)   //实参
            var l2 = show('wdnmd',18)
            console.log(l1)
            console.log(l1.name)
            console.log(l1.sty())

构造函数

function Per(name,age){
                this.name = name
                this.age = age
            }
            var p1 = new Per('老八',30)
            console.log(p1)

原型方式+构造函数

function Per(name,age){
                this.name = name
                this.age = age 
            }
            Per.prototype.say = function(){
                console.log('1111')
            }
            var p1 = new Per('张三',15)
            console.log(p1)
