        }
            }
        }

我要达到的目的是框xm里有没有内容都可以登入 但会跳出个div提示框是否确定xm为空 是的话就执行下面的是的话就登陆 否的话就div提示框隐藏 如果xm不为空则直接登陆

但现在实际情况是这样的：我xm框里不输入东西 在zh和mm框里输上了，点登陆 跳出刚才那个div框 按框里的否的话是正常的，按是的话 他跳出密码错误提示（其实密码是正确的），密码错误提示上的确定点了以后 跳回登陆窗口 发现div提示框没隐藏（我明明写过隐藏的），然后在密码框里填入密码，再按div提示框上的是才可以正常登陆
经过证实那个跳出的密码错误提示是那个叫xm_yes的按钮里的

[wuyq11]

F11单步看看执行顺序

[llq991675974]

设断点呀。

[phoebuswei]

Users 和user一样吗！您自己写错了

[ycproc]

断点 跟踪调试

[cfesc9]

太长了，真看不完呀，像楼上说的，断点，还不行，就逐行输出调试。

[子夜__]

代码好长。。。。。。。。。。。。
