概述
http://my97.net/是一个web浏览器的日期选择控件，非常好用，做得非常棒，各种API等事件等都很方便，但是使用了4.8beta3之后，在控件上面右击会出现官网链接 ，这个是PM以及客户不能容忍的，必须干掉，但是不付费的代码是经过混淆的，现在记录一下第一次调试混淆了源代码的JS的过程。
问题描述
如下图所示：本来此处应该是快速选择日期的提示，但是。。。
一旦在控件区域点击右键就会出现下图情况：
解决过程
首先当然是去某度某歌，结果都没有，可能确实这个bug不太容易发现吧。
没办法只能自己动手了，打开核心代码发现都是经过混淆加密的，根本没办法读。。。。。。
不过还是 被我发现了些许蛛丝马迹，见http://my97.net/dp/My97DatePicker/calendar.js?最后结尾处：
这个就是官网链接地址了。
然后又去查怎么查看混淆了的源代码，结果。。。。伟大的IE可以做到，低版本的我还没看，反正IE11可以。
打开IE11的开发者工具，切到调试程序选项
就打开了真实的源码，虽然也不是很真实，但是最起码可以看得懂，当然你要点击顶端那一排小图标中的“启用优质打印”，要不然整个文档还是只有一句代码。
打开之后的源代码：

然后查找 net,nte,ent,etn,ten,tne最终找到了“ten”：
根据上下文环境得知这里就是显示快速选择的方法了，然后就搜索所有调用过此方法的地方，到这里，问题本身已经解决了，只要把 参数A置为0或者false就不会出现广告链接了，但是人家说了免费代码不能改动核心库。因此继续。。
查找_fillQS，发现在配置文件中的一个调用：
配置文件是可以随意修改的，如果不想屏蔽右键菜单就直接去掉这句，否则可以把调用方法的1改为0等，就不会出现广告链接。
至此，此次问题解决完成。
后记
其实后面看看，只要把握右键这个东西一开始也不会费太大劲，应该直接就能定位到调用的地方，然后可能会尝试把1改为0，这样也能解决问题但是不会学到这么多技巧。
发出来与大家共同学习吧！
