Jquery和js实现cookie操作手机浮层广告；附加：js获取、添加、删除cookie

1、jquery cookie包实现手机上的浮层广告

<span style="font-size:18px;">$(document).ready(function(){
//百科观察浮层广告
var adCookie=$.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;
}
};</span>

2.js cookie实现手机上的浮层广告

<span style="font-size:18px;">$(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 docCookie = readCookie("docCookie");
var docFootAds = $("#guancha_foot_ads");

if(docCookie!="docWirteCookie"){
alert(docCookie);
writeCookie("docCookie","docWirteCookie");
docFootAds.show();
}
if(docCookie=="docWirteCookie"){
alert(docCookie);
docFootAds.hide();
}

//关闭广告，隐藏浮层
$("#closeAd").click(function(){
$("#wapDocCookie").hide();
});
});</span>

3..网上js操作cookie的资料

js获取cookie

<span style="font-size:18px;">//js获取cookie
/*获取Cookie值*/
function getCookie(c_name)
{
if(document.cookie.length>0){
c_start=document.cookie.indexOf(c_name + "=")
if(c_start!=-1){
c_start=c_start + c_name.length+1
c_end=document.cookie.indexOf(";",c_start)
if(c_end==-1) c_end=document.cookie.length
return unescape(document.cookie.substring(c_start,c_end))
}
}
return ""
}</span>

 

**********************************//JS操作cookies方法! *****************************************************************

<span style="font-size:18px;">//写cookies
function setCookie(name,value)
{
var Days = 30;
var exp = new Date();
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
//读取cookies
function getCookie(name)
{
var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");

if(arr=document.cookie.match(reg))

return unescape(arr[2]);
else
return null;
}
//删除cookies
function delCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null)
document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
//使用示例
setCookie("name","hayden");
alert(getCookie("name"));
//如果需要设定自定义过期时间
//那么把上面的setCookie　函数换成下面两个函数就ok;

//程序代码
function setCookie(name,value,time)
{
var strsec = getsec(time);
var exp = new Date();
exp.setTime(exp.getTime() + strsec*1);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getsec(str)
{
alert(str);
var str1=str.substring(1,str.length)*1;
var str2=str.substring(0,1);
if (str2=="s")
{
return str1*1000;
}
else if (str2=="h")
{
return str1*60*60*1000;
}
else if (str2=="d")
{
return str1*24*60*60*1000;
}
}
//这是有设定过期时间的使用示例：
//s20是代表20秒
//h是指小时，如12小时则是：h12
//d是天数，30天则：d30
setCookie("name","hayden","s20");</span>
