Question

情景是：在悬停按钮时，将看到报价即将到来的下一个可用时间。我用了代码

function closest (num, arr) {
        var closestNext=10000;
            for (var val = 0; val < arr.length; val++) {
              if (arr[val] > num) {
                if (arr[val] < closestNext)
                {
                    closestNext = arr[val];
                    }
              }

            }
            if (closestNext==10000){
                closestNext=arr[0];
            }
            return closestNext;

        }

这让我可以显示一天（我正在javascript中加载页面加载页面）。但现在的问题是，如果在每天早上10点到11点之间提出报价。优惠在关闭时如何显示数据？精心准备：假设每天下午4点提供报价。其余时间悬停在报价显示按钮上，显示“下一个报价为下午4点”。这我通过使用数组和当前时间来计算和显示解决了。现在问题是假设每个星期五上午10点都有报价，然后在结婚时它必须显示报价在“上午10点”。

如果我能够正确理解您的问题，那么这里是下一个提议日期和时间并返回适当的消息的功能。这一天是1-7（星期一），时间是24小时格式。

function getNextOffer(offer_day, offer_time) //offer_day = 4, offer_time = 16
{
    var msg = '';
    var today = new Date();
    var day_today = today.getDay();
    var time_today = today.getHours()

    if(offer_day != day_today) //different day
    {
        msg = "thurs " + offer_time; //this msg can be manipulated
    }
    else
    {
        if(time_today > offer_time) //time elapsed
        {
            msg = "next thurs " + offer_time;
        }
        else
        {
            msg = "next offer by " + offer_time;
        }
    }

    return msg;
}

编辑：多个值改变了逻辑位

//example array of offers [Fri, 12:00pm], [Thurs, 1:00pm], [Sat, 7:00pm]
var days = [[5, 12], [4, 13], [6, 19]];

function getNextOffer(days)
{
    var msg = '';
    var today = new Date();
    var day_today = today.getDay();
    var time_today = today.getHours();
    var pre_offer_day = 8;
    var pre_offer_time = 25;

    for(i=0; i < days.length; i++)
    {
        var offer_day = days[i][0];
        var offer_time = days[i][1];

        if(pre_offer_day >= offer_day)
        {
            if(offer_day > day_today)
            {
                msg = "next " +  offer_day + " at " + offer_time;
                pre_offer_day = offer_day;
                pre_offer_time = offer_time;
            }
            else if(offer_day == day_today && offer_time > time_today)
            {
                msg = "next " +  offer_day + " at " + offer_time;
                pre_offer_day = offer_day;
                pre_offer_time = offer_time;
            }
        }
    }

    \\if no more offers in this week set the default msg
    if(pre_offer_day == 8 && pre_offer_time == 25)
    {
        msg = msg = "next offer by thurs 10am";
    }
    return msg;
}

最近的第二天和javascript的时间
