Make a cookie expire in 30 seconds
提问by Odyssey
Could someone update the following code to make the cookie expire in 30 seconds.
有人可以更新以下代码以使 cookie 在 30 秒内过期。
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;
}

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=/";
}

You can specify the maximum age in seconds when setting a cookie:
您可以在设置 cookie 时以秒为单位指定最大年龄:
function setCookie(name, value, maxAgeSeconds) {
var maxAgeSegment = "; max-age=" + maxAgeSeconds;
document.cookie = encodeURI(name) + "=" + encodeURI(value) + maxAgeSegment;
}
Usage:
用法:
setCookie("username", "blaise", 30);
