js类、实例对象
一 、js类
1) 定义:
function cP(id,name){
???
??? this.id = id;
??? this.name = name;
??? this.method = function(){alert("hello");};
}
2) 给cP类添加属性:
cP.prototype.method1 = function){alert("this is another method of cP");};
3) cP类调用:
var v = new cP(3,"jack");
二、js实例对象
1) 定义
? 1.1) var o = {
???????????? i:4,
???????????? method:function(){alert("hello");}
??????? };
?1.2) var o = new Object();
??????????? o.i = 4;
??????????? o.method = function(){alert("hello");
????? };
?1.3) var o = {};
??????????? o.i = 4;
??????????? o.method = function(){alert("hello");
????? };
2) 调用
o.method();
