javascript - JavaScript 中的日期格式

Question

我想获取日期差异:

var dateString='2015-04-07T10:46:25Z';
var dt = new Date(value);
var now = new Date();
var _MS_PER_DAY = 1000 * 60 * 60 * 24;
var utc1 = Date.UTC(dt.getFullYear(), dt.getMonth(), dt.getDate());
var utc2 = Date.UTC(now.getFullYear(), now.getMonth(), now.getDate());
var days=Math.floor((utc2 - utc1) / _MS_PER_DAY);//this is 415

结果必须采用以下格式:415d, 03:06:33

最好的方法是什么？我得到了日期，但缺少时间。

Try this

    var datetime = new Date("2015-04-07T10:46:25Z");
    var now = new Date();
    if (datetime < now) {
            var diffTime = now - datetime;
        }else{
            var diffTime = datetime - now;
        }
        var days = Math.floor(diffTime / 1000 / 60 / (60 * 24));

        var dateDiff = new Date( diffTime );

         var hour = dateDiff .getHours().toString().length == 1 ? '0' + dateDiff .getHours() : dateDiff .getHours();
         var minute = dateDiff.getMinutes().toString().length == 1 ? '0' + dateDiff.getMinutes() : dateDiff.getMinutes();
         var seconds = dateDiff.getSeconds().toString().length == 1 ? '0' + dateDiff.getSeconds() : dateDiff.getSeconds();

        console.log(days + "d "+ hour  + ":" + minute  + ":" + seconds);
