Step: optimization parameter passing parametric data transfer format using json
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Title</title></head><body><script type="text/html">functionPerson(name,age,sex){// 1. 自动创建空对象，把对象地址给了this，this → 新对象// var this = new Object();// 2. this 给空对象绑定属性和行为this.name = name;this.age = age;this.sex = sex;// 3. 返回thisreturnthis;}var p =newPerson();</script><script>functionDog(options){// 属性this.name = options.name;this.age = options.age;this.dogFriends = options.dogFriends;// 行为this.eat=function(someThing){
console.log(this.name +'吃'+ someThing);};this.run=function(someWhere){
console.log(this.name +'跑'+ someWhere);}}var options ={"name":"小花","age":1,"dogFriends":["小草","小可"]};var smallDog =newDog(options);
console.log(smallDog.name,smallDog.age,smallDog.dogFriends);
smallDog.run('操场');</script></body></html>
Step Two: Using the prototype property prototype share the same inventory release function, to save memory space. If you are created when an object is initialized, and each object will create a function that waste of space
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Title</title></head><body><script type="text/html">functionPerson(name,age,sex){// 1. 自动创建空对象，把对象地址给了this，this → 新对象// var this = new Object();// 2. this 给空对象绑定属性和行为this.name = name;this.age = age;this.sex = sex;// 3. 返回thisreturnthis;}var p =newPerson();</script><script>functionDog(options){// 属性this.name = options.name;this.age = options.age;this.dogFriends = options.dogFriends;}
Dog.prototype.eat=function(someThing){
console.log(this.name +'吃'+ someThing);};
Dog.prototype.run=function(someWhere){
console.log(this.name +'跑'+ someWhere);};var options ={"name":"小花","age":1,"dogFriends":["小草","小可"]};var smallDog =newDog(options);
console.log(smallDog.name,smallDog.age,smallDog.dogFriends);
smallDog.run('操场');</script></body></html>
All things are placed directly in the prototype object
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Title</title></head><body><script type="text/html">functionPerson(name,age,sex){// 1. 自动创建空对象，把对象地址给了this，this → 新对象// var this = new Object();// 2. this 给空对象绑定属性和行为this.name = name;this.age = age;this.sex = sex;// 3. 返回thisreturnthis;}var p =newPerson();</script><script>functionDog(options){this._init(options);}
Dog.prototype ={
_init:function(options){this.name = options.name;this.age = options.age;this.dogFriends = options.dogFriends;},
eat :function(someThing){
console.log(this.name +'吃'+ someThing);},
run :function(someWhere){
console.log(this.name +'跑'+ someWhere);}};var options ={"name":"小花","age":1,"dogFriends":["小草","小可"]};var smallDog =newDog(options);
console.log(smallDog.name,smallDog.age,smallDog.dogFriends);
smallDog.run('操场');</script></body></html>
