function peple(){ this.hp=0; this.act = 30; this.name = ""; this.x=0; this.y=0; this.move =function(x,y){ document.write(this.name+"正在移动到"+x+","+y); } this.eat=function(){ document.write("正在吃"); } }
类的实例:创建一个对象
var p1 = new peple(); p1.name="阿达"; p1.hp = 100; p1.move(100,100); p1.move(22,200);在类外部动态扩展方法
p1.fire = function(x,y){ document.write(this.name+"正在开火向"+x+","+y); p1.hp--; }
调用函数外部定义的函数
p1.fire(00,00); p1.fire(43,22); p1.fire(66,88); document.write("hp="+p1.hp);
