是干什么用的，作用是什么？
[解决办法]
- 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1111var 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|125727|125728|125729|108860|"//它的作用体现在下面这一句//如果当前地址中存在from参数，且参数的值在f_from中可以找得到,那么跳转页面地址至：http://www.nimenzhenshifsdfsf.com/if(from >1 && f_from.indexOf(from + "|") >= 0) window.location.href="http://www.nimenzhenshifsdfsf.com/";
[解决办法]
判断请求的内容，如：from=131900中的131900是否包含在f_from中，如果在执行这个：window.location.href="http://www.nimenzhenshifsdfsf.com/";
不在此中不执行
不过这种方式不好吧，如：form=644也在其中，因124644|这个是可以找到的
[解决办法]
呵呵，应该是人家的参数值都是至少等于6位的，不会出现你说的情况才是
否则，别人肯定会在最前面也加上个|了
