在JavaScript中获取当前日期和时间

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

. getday返回星期几。你需要用. getdate代替。 . getmonth返回0到11的值。您需要在结果中添加1以获得“人类”月份数。

其他回答

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

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。

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>

我想现在分享我的答案已经很晚了，但我认为这是值得的。

function __getCurrentDateTime(format){
    var dt=new Date(),x,date=[];
    date['d']=dt.getDate();
    date['dd']=dt.getDate()>10?dt.getDate():'0'+dt.getDate();
    date['m']=dt.getMonth()+1;
    date['mm']=(dt.getMonth()+1)>10?(dt.getMonth()+1):'0'+(dt.getMonth()+1);
    date['yyyy']=dt.getFullYear();
    date['yy']=dt.getFullYear().toString().slice(-2);
    date['h']=(dt.getHours()>12?dt.getHours()-12:dt.getHours());
    date['hh']=dt.getHours();
    date['mi']=dt.getMinutes();
    date['mimi']=dt.getMinutes()<10?('0'+dt.getMinutes()):dt.getMinutes();
    date['s']=dt.getSeconds();
    date['ss']=dt.getSeconds()<10?('0'+dt.getSeconds()):dt.getSeconds();
    date['sss']=dt.getMilliseconds();
    date['ampm']=(dt.getHours()>=12?'PM':'AM');
    x=format.toLowerCase();
    x=x.indexOf('dd')!=-1?x.replace(/(dd)/i,date['dd']):x.replace(/(d)/i,date['d']);
    x=x.indexOf('mm')!=-1?x.replace(/(mm)/i,date['mm']):x.replace(/(m)/i,date['m']);
    x=x.indexOf('yyyy')!=-1?x.replace(/(yyyy)/i,date['yyyy']):x.replace(/(yy)/i,date['yy']);
    x=x.indexOf('hh')!=-1?x.replace(/(hh)/i,date['hh']):x.replace(/(h)/i,date['h']);
    x=x.indexOf('mimi')!=-1?x.replace(/(mimi)/i,date['mimi']):x.replace(/(mi)/i,date['mi']);
    if(x.indexOf('sss')!=-1){   x=x.replace(/(sss)/i,date['sss']);  }
    x=x.indexOf('ss')!=-1?x.replace(/(ss)/i,date['ss']):x.replace(/(s)/i,date['s']);
    if(x.indexOf('ampm')!=-1){  x=x.replace(/(ampm)/i,date['ampm']);    }
    return x;
}

console.log(__getCurrentDateTime());  //returns in dd-mm-yyyy HH:MM:SS
console.log(__getCurrentDateTime('dd-mm-yyyy'));    //return in 05-12-2016
console.log(__getCurrentDateTime('dd/mm*yyyy'));    //return in 05/12*2016
console.log(__getCurrentDateTime('hh:mimi:ss'));    //return in 13:05:30

console.log (__getCurrentDateTime (' h mi: ss ampm '));//下午1:5:30返回

对于真正的mysql样式输出使用下面的函数:2019/02/28 15:33:12
