JavaScript中set与get方法用法示例

var person ={ _name : "chen", age:21, set name(name) {this._name = name;},get name() {return this._name;}}
console.log(person.name)

var p = {
  name:"chen",
  work:function() {
    console.log("wording...");
  },
  _age:18,
  get age(){
    return this._age;
  },
  set age(val) {
    if (val<0 || val> 100) {//如果年龄大于100就抛出错误
      throw new Error("invalid value")
    }else{
      this._age = val;
    }
  }
};
console.log(p.name);//输出chen
