大家好，请你帮我把这个cookie设置为30天后过期而不是1.

Hi guys could you help me please to set this cookie to expire in 30 days in stead of 1.

function createCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*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; } function eraseCookie(name) { createCookie(name,"",-1); }

推荐答案

如果 If date.setTime(date.getTime()+(days*24*60*60*1000));

将到期时间设置为1天，那么这不是一个很好的飞跃

sets the expiry to 1 day hence, then it's not a great leap to work out that

date.setTime(date.getTime()+(days*30*24*60*60*1000));

会将其延长至30天
