使用：
cookieUtil.set(key,value,' ', '/');
引入jquery.cookie.js
var cookieUtil={
set :function(name,value,expires,path,domain,secure){
var cookieText=encodeURIComponent(name)+'='+
encodeURIComponent(value);
if(expires instanceof Date){
cookieText+=';expires='+expires.toGMTString();
}
if(path){
cookieText+=';path='+path;
}
if(domain){
cookieText+=';domain='+domain;
}
if(secure){
cookieText+=';secure';
}
document.cookie=cookieText;
},
get:function(name){
var cookieName=encodeURIComponent(name)+'=',
cookieStart=document.cookie.indexOf(cookieName),
cookieValue=null;
if(cookieStart>-1){
var cookieEnd=document.cookie.indexOf(';',cookieStart);
if(cookieEnd==-1){
cookieEnd=document.cookie.length;
}
cookieValue=decodeURIComponent(document.cookie.substring(cookieStart+cookieName.length,cookieEnd))
}
return cookieValue;
},
unset:function(name,path,domain,secure){
this.set(name,'',new Date(0),domain,path)
}
}
function setCookieDate(day){
var date=null;
if(typeof day=='number'&&day>0){
date=new Date();
date.setDate(date.getDate()+day);
}else{
throw new Error('!!')
}
return date;
}
function getUUID() {
return 'xxxx-xxxx-xxxx-xxxx-xxxx'.replace(/[xy]/g, function(c) {
var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8);
return v.toString(16);
});
};
