?>[code=PHP][/code]

------解决方案--------------------
你应该遇到这样类似的错误：
Using $this when not in object context


------解决方案--------------------
一大堆问题。
function sendMail是类之外的函数，为什么会有$this这样的字眼呢？
phpMailer()函数也未定义。。
总之，lz可以先看看 OOP的相关资料
------解决方案--------------------
其它方面的知识自己恶补一下吧。
php面向对象编程

PHP code

      $this->dbCon->errorShow = true;
      $this->js = $this->root->JavaScript();
