我有一些我想在 1 小时内过期的 cookie 代码,代码是:
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
sWhere = "http://google.com";
if(!readCookie('viewcheck')){
createCookie('viewcheck',1,1);
} else {
window.location = sWhere;
}
我怎样才能让cookie在一小时内过期?
