路径1：/1/2/3/4.php
路径2：/5/6/7/8.php
网址1：域名.c-o-m/11.php

Answer 2

location.href.indexOf("/2/")>=0||location.href.indexOf("/6/")>=0

Answer 3

为什么用js呢，你用PHP不是更方便嘛！
直接用PHP获取当前网址，就OK了

追问

404页面，规定用静态呢，我把原来的路径2/3/4.php网页给前面加了个路径1/，用户点击外链的网址.c-o-m/2/3/4.php，提示错误404了，现在想自动跳到1/2/3/4.php

追答

那就用JS获取当前的URL地址，也有这个功能的
