求大家看一行代码的作用
这个里面的 var f_from = "124638|124640|124641|124642|124644|124646|124648|124650|125700|125701|125702|125703|125704|125705|125706|125707|125708|125709|125710|125711|125712|125713|125714|125715|125716|125717|125720|125721|125722|125724|125725|125726|125727|125728|125729|108860|"
是干什么用的，作用是什么？

- JScript code
//在当前地址中匹配form=整型&guid=整型
var murl = window.location.href.match(/from=(\d+)\&gid=(\d+)/);
//如果上面没有匹配到，则from=1否则from=上面匹配到的值
//比如：http://www.abc.com/?from=1111&gid=2222;则下面from的值就为1111
var from = murl == null ? 1 : murl[1];
//下面定义的f_from就是上面的from可能出现的一系列的值，可能是用来屏蔽的
var f_from = "124638|124640|124641|124642|124644|124646|124648|124650|125700|125701|125702|125703|125704|125705|125706|125707|125708|125709|125710|125711|125712|125713|125714|125715|125716|125717|125720|125721|125722|125724|125725|125726|
