JS真是一門經典腳本語言，近日看一些JS的面向對象編程的文章，記錄下來。
1.構建類：
??? JS中構建類，其實就是構建類的一個構造方法。如下：
var
?Foo?
=
?
function
?()
????{
????????
this
.name?
=
?
"
aaa
"
;
????????
this
.b?
=
?
"
bbb
"
;
????????
this
.sayHello?
=
?
function
?()
????????{
????????????alert(
"
welcome:??
"
+
this
.name);
????????}
????};
????
var
?foo?
=
?
new
?Foo();
????foo.name?
=
?
"
wh
"
;
????foo.sayHello();
或者如下：
function?A(){???????????
????var?locate1?=?"1oh";????
????this.locate2?=?"2oh";????
????var?method1?=?function(){????
????????alert(locate1);????
????}????
????this.method2?=?function(){????
????????alert(this.locate2);????
????????method1();????
????}???????????????????????????????????
}?
A對象的locate1與method1是private級別的; locate2與method2是public級別的。??????????
