javascript设置带有过期时间的cookie [英] javascript set cookie with expire time

问题描述

我正在通过 Javascript 设置一个 cookie，它工作正常，但没有占用我给出的过期时间.无论我提供什么，它都会继续获取会话值，以下是我从 此处

I am setting a cookie by Javascript and it is working fine but it is not taking the expire time I am giving. It keeps on taking session value regardless of what I give, below is the code which I took from here

var now = new Date();
var time = now.getTime();
var expireTime = time + 1000*60;
now.setTime(expireTime);
var tempExp = 'Wed, 31 Oct 2012 08:50:17 GMT';
document.cookie = aaa+'='+sStr+';expires='+now.toGMTString()+';path=/';

我尝试给出硬编码值，但它仍然在 chrome 开发工具中显示为会话过期

I tried giving hard-coded value but still it is showing expire as session in chrome dev tool

var tempExp = 'Wed, 31 Oct 2012 08:50:17 GMT';
document.cookie = aaa+'='+sStr+';expires='+tempExp+';path=/';

知道我做错了什么吗?

推荐答案

我已经把时间设置为 1000*36000.

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'
}
