javascript - 使 cookie 在 30 秒内过期

Question

有人可以更新以下代码使 cookie 在 30 秒后过期。

function setCookie(c_name, value, exdays) {
    var exdate = new Date();
    exdate.setDate(exdate.getDate() + exdays);
    var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
    document.cookie = c_name + "=" + c_value;
}

Answer 1

function createCookie(name, value) {
   var date = new Date();
   date.setTime(date.getTime()+(30*1000));
   var expires = "; expires="+date.toGMTString();

   document.cookie = name+"="+value+expires+"; path=/";
}
