javascript - Javascript 日期解析

Question

我有一个 JSON 服务为我提供分钟。然后我希望将这些分钟转换为 DD:HH:MM 格式。[天，小时，分钟]

谁能指出我正确的方向或告诉我如何做到这一点？

谢谢德文

Answer 1

您可以创建一个通用函数来删除尽可能高的数字，然后再继续处理剩余的数字：http: //jsfiddle.net/sL43t/1/。

var arr = [];
var value = 5467;

var gain = function(minutes) {
    var amount = Math.floor(value / minutes);
    arr.push(amount < 10 ? "0" + amount : amount);  // add zero padding if needed
    value %= minutes;
};

gain(24 * 60);  // minutes per day
gain(60);       // minutes per hour
gain(1);        // minutes per minute

var str = arr.join(":");

Answer 2

您可以使用以下方法将分钟转换为天、小时和分钟：

// Helper
function z(n) {
  return (n<10? '0' : '') + n;
}

var n = 5467;
var days = n / 1440 | 0;
var hours = n % 1440 / 60 | 0;
var mins = n % 60;

alert( z(days) + ':' + z(hours) + ':' + z(mins) ); // 03:19:07

Answer 3

var t = 123456; // the given minutes

var days = Math.floor(t / (60 * 24));
var hours = Math.floor((t - days * 60 * 24) / 60);
var mintues = t - days * 60 * 24 - hours * 60;

Answer 4

// assuming obj.totalMin to be total minutes
var obj = {
    totalMin : 4859
}

var days = Math.floor( obj.totalMin / (60 * 24));          
var hours = Math.floor( obj.totalMin / 60) - (days * 24);          
var minutes = obj.totalMin % 60;

document.write (days + ":" + hours + ":" + minutes);

Answer 5

如果您不想为此编写自己的函数，您可以将数字转换为毫秒并使用它来创建日期对象。然后使用您选择的任何格式输出该日期对象。

Answer 6

试试这个

        var totalMinutes = ;
        var days = totalMinutes/1440;
        var totalHours = totalMinutes%1440;
        var hours = totalHours/60;
        var minutes = totalHours%60;
        alert("DD:"+days+" HH:"+hours+" MM:"+minutes);

我知道你找到了答案，但只是把它扔在那里，因为这对我来说似乎更容易，也许可以帮助别人：

function makeTime(v, lead) {
    v = parseInt(v); // ensures variable is an integer to do math too
    var days = Math.floor(v/1440),
        hrs = Math.floor(v/60 - (days*24)),
        mins = xmins % 60;
    var ret = {
        days: lead ? "" + (days < 10 ? "0" + days : days) : days,
        hrs: lead ? "" + (hrs < 10 ? "0" + hrs : hrs) : hrs,
        mins: lead ? "" + (mins < 10 ? "0" + mins : mins) : mins
    };
    ret.combo = ret.days + ":" + ret.hrs + ":" + ret.mins;
    return ret;
}

var xmins = 11404; // ou can se your data or whatever, this is just an example of minutes
var breakDown = makeTime(xmins); // this will return pure integers on each value
    //  OR!!
var breakDown = makeTime(xmins, true); // the true parameter just simply decides if you want leading variable, and string on each

// use

$("#eleID").text(breakDown.combo);
