1、將一般格式時間轉換為時間戳：

var systime = "2018年04月28日 16:01:09"; systime = systime.replace('年', "/").replace('月', "/").replace('日', ''); systime = new Date(systime).getTime();

2、將毫秒數轉換為時分秒：

var runtime = 6*60*60*1000; var day = Math.floor(runtime/(24*60*60*1000)); var h = Math.floor((runtime%(24*60*60*1000))/(60*60*1000)); var m = Math.floor(((runtime%(24*60*60*1000))%(60*60*1000))/(60*1000)); var s = Math.floor((((runtime%(24*60*60*1000))%(60*60*1000))%(60*1000))/1000);

3、動態顯示獲取到的系統時間和時長：

<div id="serviceTime"></div> var serviceTime = document.getElementById("serviceTime");console.log("========【獲取系統時間和時長】模塊開始========"); $.ajax({ type: "POST", url: "/monitor/monitoring/nodes_info/", data: {}, dataType: 'json', timeout: 1000 * 60, success: function(obj){ if(obj){ //解析當前時間 var systime = obj.sysinfo.systime;//獲取當前時間："2018年04月28日 16:01:09" systime = systime.replace('年', "/").replace('月', "/").replace('日', ''); systime = new Date(systime).getTime(); console.log("當前時間時間戳："); console.log(systime); //解析時長 var runtime = obj.sysinfo.runtime;//獲取當前時長："13天7小時58分17秒" var indexOfDay = runtime.indexOf("天"); var indexOfHour1 = runtime.indexOf("小"); var indexOfHour2 = runtime.indexOf("時"); var indexOfMinutes = runtime.indexOf("分"); var indexOfSecond = runtime.indexOf("秒"); var runtimeDay = runtime.substring(0, indexOfDay); var runtimeHour = runtime.substring(indexOfDay+1, indexOfHour1); var runtimeMinutes = runtime.substring(indexOfHour2+1, indexOfMinutes); var runtimeSecond = runtime.substring(indexOfMinutes+1, indexOfSecond); runtime = runtimeDay*24*60*60*1000 + runtimeHour*60*60*1000 + runtimeMinutes*60*1000 + runtimeSecond*1000; console.log("當前時長毫秒數："); console.log(runtime); setInterval(function(){ var time = new Date(systime); var year = time.getFullYear(); var month = time.getMonth() + 1; var date = time.getDate(); if (date >= 0 && date <= 9) { date = "0" + date; } var hour = time.getHours(); if (hour >= 0 && hour <= 9) { hour = "0" + hour; } var minutes = time.getMinutes(); if (minutes >= 0 && minutes <= 9) { minutes = "0" + minutes; } var seconds= time.getSeconds(); if (seconds >= 0 && seconds <= 9) { seconds = "0" + seconds; } var day = Math.floor(runtime/(24*60*60*1000)); var h = Math.floor((runtime%(24*60*60*1000))/(60*60*1000)); var m = Math.floor(((runtime%(24*60*60*1000))%(60*60*1000))/(60*1000)); var s = Math.floor((((runtime%(24*60*60*1000))%(60*60*1000))%(60*1000))/1000); serviceTime.innerHTML = "運行時長：" + day + "天" + h + "時" + m + "分" + s + "秒 "+ " 系統時間：" + year + "年" + month + "月" + date + "日 " + hour + ":" + minutes + ":" + seconds; systime += 1000; runtime += 1000; }, 1000); }else{ toastr.error("獲取系統時間和時長時返回數據為空！", "警告"); console.log("獲取系統時間和時長時返回數據為空！"); } }, error: function(msg){ toastr.error("獲取系統時間和時長時系統錯誤！", "警告"); console.log("獲取系統時間和時長時系統錯誤！"); console.log(msg); } });
