javascript set cookie with expire time
I've set the time to 1000*36000.
function display() {
var now = new Date();
var time = now.getTime();
var expireTime = time + 1000*36000;
now.setTime(expireTime);
document.cookie = 'cookie=ok;expires='+now.toUTCString()+';path=/';
//console.log(document.cookie); // 'Wed, 31 Oct 2012 08:50:17 UTC'
}
Below are code snippets to create and delete a cookie. The cookie is set for 1 day.
// 1 Day = 24 Hrs = 24*60*60 = 86400.
By using max-age:
- Creating the cookie:
document.cookie = "cookieName=cookieValue; max-age=86400; path=/;";
- Deleting the cookie:
document.cookie = "cookieName=; max-age=- (any digit); path=/;";
By using expires:
- Syntax for creating the cookie for one day:
var expires = (new Date(Date.now()+ 86400*1000)).toUTCString(); document.cookie = "cookieName=cookieValue; expires=" + expires + 86400) + ";path=/;"
Here's a function I wrote another application. Feel free to reuse:
function writeCookie (key, value, days) {
var date = new Date();
// Default at 365 days.
days = days || 365;
// Get unix milliseconds at current time plus number of days
date.setTime(+ date + (days * 86400000)); //24 * 60 * 60 * 1000
window.document.cookie = key + "=" + value + "; expires=" + date.toGMTString() + "; path=/";
return value;
};
