1.第一种：使用jQuery的cookie库 
例子就是现在正在使用的js,相关代码如下： 
$(document).ready(function () { 
var adCookie=$.cookie("docCookie"); 
//如果本地没有cookie，将词条cookie写入本地 
if(adCookie!="adDocCookie"){ 
$("#wapDocCookie").show(); 
} 
//如果本地存在词条cookie，不显示浮层 
if(adCookie=="adDocCookie"){ 
$("#wapDocCookie").hide(); 
} 
//关闭广告，隐藏浮层 
$("#closeAd").click(function(){ 
$("#wapDocCookie").hide(); 
$.cookie("docCookie","adDocCookie",{expires:60}); 
}); 
 
}); 
//jQuery cookie library 
jQuery.cookie = function(name, value, options) { 
if (typeof value != 'undefined') { // name and value given, set cookie 
options = options || {}; 
if (value === null) { 
value = ''; 
options.expires = -1; 
} 
var expires = ''; 
if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { 
var date; 
if (typeof options.expires == 'number') { 
date = new Date(); 
date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000)); 
} else { 
date = options.expires; 
} 
expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE 
} 
var path = options.path ? '; path=' + (options.path) : ''; 
var domain = options.domain ? '; domain=' + (options.domain) : ''; 
var secure = options.secure ? '; secure' : ''; 
document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); 
} else { // only name given, get cookie 
var cookieValue = null; 
if (document.cookie && document.cookie != '') { 
var cookies = document.cookie.split(';'); 
for (var i = 0; i < cookies.length; i++) { 
var cookie = jQuery.trim(cookies[i]); 
// Does this cookie string begin with the name we want? 
if (cookie.substring(0, name.length + 1) == (name + '=')) { 
cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); 
break; 
} 
} 
} 
return cookieValue; 
} 
}; 
2.第二种：自己写一个js操作cookie的实例 
相关js如下： 
$(document).ready(function() { 
 
function writeCookie(name,value) 
{ 
var exp = new Date(); 
exp.setTime(exp.getTime() + 7*24*60*60*1000); 
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); 
} 
//读取cookies 
function readCookie(name) 
{ 
var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)"); 
if(arr=document.cookie.match(reg)){ 
return unescape(arr[2]); 
}else { 
return null; 
} 
} 
var adCookie = readCookie("adCookie"); 
 
if(adCookie!="adDocCookie"){ 
$("#wapDocCookie").show(); 
} 
//如果本地存在词条cookie，不显示浮层 
if(adCookie=="adDocCookie"){ 
$("#wapDocCookie").hide(); 
} 
 
//关闭广告，隐藏浮层 
$("#closeAd").click(function(){ 
$("#wapDocCookie").hide(); 
}); 
}); 
</pre> 
</div> 
<!--广告样式 --> 
<style type="text/css">
