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

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();
}
