关于js类的问题，急。。。

我把一个包含javascript脚本的html页面中的js代码提出来放到外部的js文件中，因为原代码比较长，我砍掉了大部分，只留下 核心的一些，在外部文件中我用到了类，但是运行的时候老说我的类没定义，找了很多资料我都没找出原因，请高手帮帮忙，看问题出在哪里，先谢谢大家了html原文件是这样的（经过简化的）,运行时正常的：

  2.   

    采用必包可以解决，因为你放在外部的时候，没有自动调用，
    可以考虑把你的代码放在(function(){
    //dosomething
    })();
      

  3.   

    LZ 我是真的想看看你代码, 但是第一段代码调不通:
    ptza未定义, 还有%%符号 不能识别, 还有if逻辑错误, ect..最好你确定调通了, 在用HTML发上来吧.

    刚刚按xfsnero所说的修改了下还是不行还是谢谢你哟
      

  7.   

    'Ptz0'未定义
    'ptzas'为空或未定义
      

  8.   

    'Ptz0'未定义 
    'ptzas'为空或不是对象
    上面那写错了，呵呵
    帮我看下，谢谢了
      

  9.   

    我这里看不是'Ptz0'未定义（是不是你没加载到文件），'ptzas'为空或不是对象
    下面是修改过的，内容不全，无法继续调试<html>
