我有一个脚本,打印当前的日期和时间在JavaScript,但日期总是错误的。代码如下:

var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDay() + "/" + currentdate.getMonth() 
+ "/" + currentdate.getFullYear() + " @ " 
+ currentdate.getHours() + ":" 
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();

它应该打印18/04/2012 15:07:33和打印3/3/2012 15:07:33

Here is my work around clock full format with day, date, year and time and make Sure the date of your PC is set to the right date and if you are using PHP make sure in php.ini date.timezone= xx where xx your current timezone function startTime() { var today=new Date(); // 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 var suffixes = ['','st','nd','rd','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','st','nd','rd','th','th','th','th','th','th','th','st','nd','rd']; var weekday = new Array(7); weekday[0] = "Sunday"; weekday[1] = "Monday"; weekday[2] = "Tuesday"; weekday[3] = "Wednesday"; weekday[4] = "Thursday"; weekday[5] = "Friday"; weekday[6] = "Saturday"; var month = new Array(12); month[0] = "January"; month[1] = "February"; month[2] = "March"; month[3] = "April"; month[4] = "May"; month[5] = "June"; month[6] = "July"; month[7] = "August"; month[8] = "September"; month[9] = "October"; month[10] = "November"; month[11] = "December"; document.getElementById('txt').innerHTML=(weekday[today.getDay()] + ',' + " " + today.getDate()+'<sup>'+suffixes[today.getDate()]+'</sup>' + ' of' + " " + month[today.getMonth()] + " " + today.getFullYear() + ' Time Now ' + today.toLocaleTimeString()); t=setTimeout(function(){startTime()},500); } <style> sup { vertical-align: super; font-size: smaller; } </style> <html> <body onload="startTime()"> <div id="txt"></div> </body> </html>

var currentdate = new Date();

    var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1) 
    + "/" + currentdate.getFullYear() + " @ " 
    + currentdate.getHours() + ":" 
    + currentdate.getMinutes() + ":" + currentdate.getSeconds();

将. getday()方法更改为. getdate(),并将1添加到month,因为它从0开始计算月份。

您需要使用getDate()来获取日期部分。getDay()函数返回日期(Sunday = 0, Monday = 1…),getMonth()返回一个基于0的索引,因此需要将其增加1。

 var currentdate = new Date(); 

 var datetime = "Last Sync: " + currentdate.getDate() + "/"+  (parseInt(currentdate.getMonth())    + 1)
   + "/" + currentdate.getFullYear() + " @ "  
   + currentdate.getHours() + ":"  
   + currentdate.getMinutes() + ":" + currentdate.getSeconds(); 
function display_c(){   
    var refresh = 1000; // Refresh rate in milli seconds    
    mytime = setTimeout('display_ct()', refresh)    
}

function display_ct() {

    var strcount    
    var currentdate = new Date();

    document.getElementById('ct').innerHTML = currentdate.toDateString() + " " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds();

    tt = display_c();   
}


id = 'ct'     // Replace in Your id

onload = "display_ct();"     // Type inside a Body Tag

我们可以用: new Date().toLocaleDateString()获取当前日期和 new Date().toLocaleTimeString()获取当前时间

Ex:

const date = new Date().toLocaleDateString();
const time = new Date().toLocaleTimeString();
const date = new Date()
console.log(date.toLocaleTimeString("en-us", {timeStyle: "medium"})) // Only Time 
console.log(date.toLocaleString()) // For both Date and Time
