请js强人讲解一下上面这段代码
XPH_AddSkill(b) 最不解的是b这个参数。。。

[knightzhuwei]

这段代码有什么特殊么？
b是个对象啊

[knightzhuwei]

for(var c in b)
{
alert(b[c]);
}
不就是遍历b的属性么

对呀 它就是个对象啊

这个我知道，我想问的是b=下面XPH_AddSkill(...);? 这里有些不解

[knightzhuwei]

XPH_AddSkill({a:1,b:2});
和
var o={a:1,b:2};
XPH_AddSkill(o)是一个道理

[Quote=引用 5 楼 knightzhuwei 的回复:]

XPH_AddSkill({a:1,b:2});
和
var o={a:1,b:2};
XPH_AddSkill(o)是一个道理

嗯 分析很到位，谢谢啦！
