网站做静态化后，部分页面传入的参数得改成用js处理了。js获取页面参数有两种方法，cookie和ajax，下面总结js处理cookie的方法。

设置cookie:

function setCookie(name, value) {     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())); }

获取cookie:

function getCookie(Name) {     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 ""     } }

删除cookie:

function deleteCookie(name) {     var expdate = new Date();     expdate.setTime(expdate.getTime() - (86400 * 1000 * 1));     setCookie(name, "", expdate); }
