Cookie过期30天 [英] Cookie expiration 30 days

问题描述

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
