修改方法：
后台风格Page_index,template.html(5)，找到“-=>”，替换成：
<img src="http://www.51one.net/tobbs/dvbbs/Skins/Default/plus.gif" onload=switchLink(this)>
然后加入下面JS到MAIN.JS中即可
var defaultSts = "off" //默认参数设置"on"=打开 , "off"=关闭
//------------代码开始-----------------
function setCookie(name, value) //cookies设置JS
{
var argv = setCookie.arguments;
var argc = setCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
if(expires!=null)
{
var LargeExpDate = new Date ();
LargeExpDate.setTime(LargeExpDate.getTime() + (expires*1000*3600*24));
}
document.cookie = name + "=" + escape (value)+((expires == null) ? "" : ("; expires=" +LargeExpDate.toGMTString()));
}
function getCookie(Name) //cookies读取JS
{
var search = Name + "="
if(document.cookie.length > 0)
{
offset = document.cookie.indexOf(search)
if(offset != -1)
{
offset += search.length
end = document.cookie.indexOf(";", offset)
if(end == -1) end = document.cookie.length
return unescape(document.cookie.substring(offset, end))
}
else return ""
}
}
function switchLink(obj) //友情链接开关JS
{
var cn="link"+self.location.hostname.toString().replace(/\./g,"")
var disp=getCookie(cn),isInit=0
if(typeof(disp)!="string"||disp=="")disp=defaultSts=="off"?"none":"block"
if(typeof(obj)=="object"){
try{
obj.onload = new Function("return false")
obj.onclick = new Function("switchLink()")
obj.style.cursor = "hand"; obj.border="0"
obj.align= "absmiddle" ; isInit=1;
}
catch(e){}
}
else{obj=window.event.srcElement;disp=disp=="none"?"block":"none"}
try{
var table=obj.parentElement.parentElement.parentElement.rows(1).cells(0).childNodes(0)
table.style.display=disp
obj.alt=(disp=="block"?"隐藏":"显示")+"友情链接"
obj.src="Skins/Default/"+(disp=="block"?"nofollow.gif":"plus.gif")
if(!isInit)setCookie(cn,disp,7) //设置保存7天
}
catch(e){}
}
//------------友情链接代码结束-----------------
