修改e/class/functions.php

例如：<ul> <a href="/e/DownSys/GetDown?classid=21&id=2319&pathid=0">1</a>&nbsp;&nbsp; <a href="/e/DownSys/GetDown?classid=21&id=2319&pathid=1">2</a><br> <a href="/e/DownSys/GetDown?classid=21&id=2319&pathid=2">3</a>&nbsp;&nbsp; <a href="/e/DownSys/GetDown?classid=21&id=2319&pathid=3">4</a></ul>
