首先感谢各位大大， 我想提一个需求， 在提示有票的同时， 还可以继续刷票， 因为有的车并不是你想坐的， 但他提示有票后， 又要手动点击刷新！！！

@creazestone: 其实不妨做一个『忽略指定车次』的功能。不过我现在没有帐号，无法调试，欢迎各位 fork 实现。

好像已经被12306封杀了，使用后就会出现Access Denied。换个IP就能打开

自动提交订单后，刷了300多次都还在继续刷是怎么回事啊？

确实，IE 的自动登录程序是不能用，GOOgle浏览器不能支付，还是不够完美

?IE上面已经可以兼容了啊 自动登录 自动刷票 修改日期 自动提交 可能是你的脚本不对吧

正确的脚本在哪里，麻烦提供一下
感觉GOOGLE 的脚本已经被封了
提交订单怎么都提交不了
IE手动提交一下就提交了

@bird2005fly 同样有这个问题，勾选了学生票之后无法自动刷新

现在生成订单时，会提示“很抱歉！当前提交订单的人过多，请稍后尝试。”，是不是请再写个JS，帮忙下哦

现上是不是不好用了，一上午都没有登录进去

今天用了下自动登录的还可以用，但是自动刷新票的不知道怎么用了。

铁道部出新手段了，会一直显示某趟车有票，但提交订单就提示没票，所以你就刷不了了，一刷还是提示有票，然后就自动停止了

估计是想把每10分钟一次的查询余票做成静态的，结果不会。。。 发送自HTC手机

自动提交订单那里铁道部是不是改程序了？我每次提交到第二次的时候都提示验证码出错了。各位有这种情况吗？

请问一下代码什么意思？_validQueryButton 与 validQueryButton什么关系

//hack into the validQueryButton function to detect query
var _validQueryButton = validQueryButton;

validQueryButton = function() {
    _validQueryButton();
    if(isAutoQueryEnabled) doQuery();
}
