写在前面写这篇文章的起因是今天在 12306 上买火车票时，被这牛逼的网站给震撼到了，靠，牛叉得让人无语的用户体验啊。就讲讲我是如何利用一个小工具做辅助，幸运地抢到了回家的卧铺票的。希望能给有需要的兄弟们做个参考。回顾下我今天网上购票的全过程，总结起来有四个难关，第一是登陆，第二是预定，第三是提交订单，第四是支付。本文的目的主要是为了在第一和第二关提供一些帮助。准备工作： 1 ， firefox 浏览器 2 ，油猴脚本扩展 GreaseMonkey （有园友反映这里看不懂啥意思，好吧，特别补充一段。 GreaseMonkey 是一个 firefox 扩展，当然，别再问我啥是扩展了，请自行 google ，简单说，就是装了这个扩展，就可以再它基础上跑一些 js 脚本，对页面做一些修改什么的。。。，）先去这个页面下载扩展， https://addons.mozilla.org/zh-cn/firefox/addon/greasemonkey/ ，下载到本地的是一个 xpi 文件，将其拖拽进 firefox 里面，就可以完成扩展的安装，重启 firefox 以后就生效，启用了 GreaseMonkey 3 ，去这个页面安装 12306 train ticket buyer 脚本， http://userscripts.org/scripts/show/122334

Get value setted in GM_setValue from a custom Firefox extension

阅读更多关于 Get value setted in GM_setValue from a custom Firefox extension

问题 Do you know if a custom Firefox extension can read values setted calling GM_setValue() from a GraseMonkey user script? 回答1: These values exists in about:config, (enter "greasemonkey" in the filter). Perhaps there exists an easier way to get them, though... 回答2: Since Greasemonkey 1.13 GM_setValue() uses an SQLite db to persist values. This DB can be accessed directly (see https://github.com/greasemonkey/greasemonkey/blob/master/modules/miscapis.js). 来源： https://stackoverflow.com/questions

Using netstat -a i got these results. This is over 200 lines. Why am i using so many ports!?! How can i... not do this? and still communicate with my application. NOTE: The 3 pages i am on (example google.com) does not match my domain (localhost) so i am pretty sure a normal xmlhttpRequest will not work (i

Why is my ajaxSuccess jQuery event not being fired in Greasemonkey?

阅读更多关于 Why is my ajaxSuccess jQuery event not being fired in Greasemonkey?

问题 I have a basic greasemonkey script shown below, in which I want to run some code every time an AJAX request is sent by the website I'm running the script on. I'm using the ajaxSuccess jQuery handler and it's not being fired. I suspect this might be because the AJAX requests are being sent with the global flag set to false (see http://docs.jquery.com/Ajax_Events). Is there some better way to achieve this that will work even when global is set to false? Code: // ==UserScript== // @name
