//保存cookie
function setCookie(name,value,iTime){
var oDate = new Date();
//设置cookie过期时间
oDate.setDate(oDate.getDate()+iTime);
document.cookie = name+'='+value+';expires='+oDate.toGMTString();
}
//获取cookie
function getCookie(name){
//cookie中的数据都是以分号加空格区分开
var arr = document.cookie.split("; ");
for(var i=0; i<arr.length; i++){
if(arr[i].split("=")[0] == name){
return arr[i].split("=")[1];
}
}
//未找到对应的cookie则返回空字符串
return '';
}
调用的时候直接:setCookie("thisId",iid,2000);
从cookie里面取值:var thisId=getCookie("thisId");
