setCookie: function(name, value, iDay){ //设置cookie: cookie名,cookie值,天数
var d = new Date();
iDay = iDay?iDay:30;
d.setTime(d.getTime()+(iDay*24*60*60*1000));
document.cookie = name+"="+value+";expires="+d.toGMTString();
},
getCookie: function(name){ //获取cookie
var arr = document.cookie.replace(' ','').split(';');
