1.设置cookie
function addCookie(name,value,expireHours){
var cookieString=name+"="+escape(value)+"; path=/";
//判断是否设置过期时间
if(expireHours>0){
var date=new Date();
date.setTime(date.getTime()+expireHours*3600*1000);
cookieString=cookieString+";expires="+date.toGMTString();
}
document.cookie=cookieString;
}
2.查询cookie
function getCookie(name){
var strcookie=document.cookie;
var arrcookie=strcookie.split("; ");
for(var i=0;i<arrcookie.length;i++){
var arr=arrcookie[i].split("=");
if(arr[0]==name)return unescape(arr[1]);
}
return null;
}
3.删除cookie
function delCookie(name){//删除cookie
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+"; path=/;expires="+exp.toGMTString();
}
