更新一下时间倒计时插件（jQUery）
1 $.fn.genTimer = function (e) { 2 function u(e) { 3 var t = Math.floor(e / n), 4 r = Math.floor((e - t * n) / 36e5), 5 i = Math.floor((e - t * n - r * 1e3 * 60 * 60) / 6e4), 6 s = Math.floor((e - t * n - r * 1e3 * 60 * 60 - i * 1e3 * 60) / 1e3); 7 return { 8 hours: ("0" + r).slice(-2), 9 minutes: ("0" + i).slice(-2), 10 seconds: ("0" + s).slice(-2), 11 dates: t 12 } 13 } 14 if (this.data("handled")) return this; 15 this.data("handled", !0); 16 var t = { 17 beginTime: new Date, 18 day_label: "day", 19 days_label: "days", 20 unitWord: { 21 hours: ":", 22 minutes: ":", 23 seconds: "" 24 }, 25 type: "", 26 callbackOnlyDatas: !1 27 }, 28 n = 864e5, 29 r = $.extend({}, t, e), 30 i = this; 31 r.targetTime = r.targetTime.replace(/\-/g, "/"); 32 r.targetTime = isNaN(r.targetTime) ? r.targetTime : parseInt(r.targetTime);37 var s = new Date(r.targetTime) - new Date(r.beginTime), 38 o = function () { 39 if (s < 0) { 40 r.callback.call(i, r.callbackOnlyDatas ? { 41 hours: "00", 42 minutes: "00", 43 seconds: "00", 44 dates: 0 45 } : "00" + r.unitWord.hours + "00" + r.unitWord.minutes + "00"); 46 clearInterval(i.interval) 47 } else { 48 var e = u(s); 49 if (r.callbackOnlyDatas) r.callback.call(i, e); 50 else if (r.type == "day") { 51 s >= n * 2 ? 52 r.callback.call(i, '<span class="day_count">' + e.dates + '</span><span class="day">' + r.days_label + '</span><span class="day_seconds">' + e.hours + r.unitWord.hours + e.minutes + r.unitWord.minutes + e.seconds + r.unitWord.seconds + "</span>") 53 : ( 54 s >= n ? 55 r.callback.call(i, '<span class="day_count">' + e.dates + '</span><span class="day">' + r.day_label + '</span><span class="day_seconds">' + e.hours + r.unitWord.hours + e.minutes + r.unitWord.minutes + e.seconds + r.unitWord.seconds + "</span>") 56 : r.callback.call(i, '<span class="seconds">' + e.hours + r.unitWord.hours + e.minutes + r.unitWord.minutes + e.seconds + r.unitWord.seconds + "</span>") 57 ); 58 } 59 else if (r.type == "diffNoDay") { 60 var t = e.hours; 61 s >= n && (t = Number(e.dates * 24) + Number(e.hours)); 62 r.callback.call(i, '<span class="hours">' + t + '</span><span class="miniutes">' + r.unitWord.hours + e.minutes + '</span><span class="senconds">' + r.unitWord.minutes + e.seconds + r.unitWord.seconds + "</span>") 63 } else { 64 var t = e.hours; 65 s >= n && (t = Number(e.dates * 24) + Number(e.hours)); 66 r.callback.call(i, '<span class="seconds">' + t + r.unitWord.hours + e.minutes + r.unitWord.minutes + e.seconds + r.unitWord.seconds + "</span>") 67 } 68 } 69 s -= 1e3 70 }; 71 i.interval = setInterval(o, 1e3); 72 o(); 73 return this 74 };
调用：
1 $(this).genTimer({ 2 beginTime: new Date(),//开始时间 3 targetTime: new Date(),//结束时间 4 type: "day", 5 callback: function (e) { 6 this.html(e) 7 } 8 })
附加：一个C#获取现在到1970-1-1毫秒算法
1 string times = (DateTime.Now.Subtract(DateTime.Parse("1970-1-1")).TotalMilliseconds - (8 * 60 * 60 * 1000)).ToString("F0");
