每天自动刷新js

function refreshAt(hours, minutes, seconds) {
    var now = new Date();
    var then = new Date();

    if(now.getHours() > hours ||
       (now.getHours() === hours && now.getMinutes() > minutes) ||
        (now.getHours() === hours && now.getMinutes() === minutes && now.getSeconds() >= seconds)) {
        then.setDate(now.getDate() + 1);
    }
    then.setHours(hours);
    then.setMinutes(minutes);
    then.setSeconds(seconds);

    var timeout = then.getTime() - now.getTime();
    setTimeout(function() {
        window.location.reload();
    }, timeout);
