来获得你应该使用的时间和日期

    new Date().toLocaleString();

>> "09/08/2014, 2:35:56 AM"

只得到你应该使用的日期

    new Date().toLocaleDateString();

>> "09/08/2014"

只得到你该用的时间

    new Date().toLocaleTimeString();

>> "2:35:56 AM"

或者如果你只是想要格式为hh:mm而不是AM/PM的美式英语时间

    new Date().toLocaleTimeString('en-US', { hour12: false, 
                                             hour: "numeric", 
                                             minute: "numeric"});
>> "02:35"

或英式英语

    new Date().toLocaleTimeString('en-GB', { hour: "numeric", 
                                             minute: "numeric"});

>> "02:35"

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。

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

为文档

function getTimeStamp() {
       var now = new Date();
       return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
                     + ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
                     .getSeconds()) : (now.getSeconds())));
}

只使用:

var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");

这应该可以达到目的:

function dateToString(date) {
    var month = date.getMonth() + 1;
    var day = date.getDate();
    var dateOfString = (("" + day).length < 2 ? "0" : "") + day + "/";
    dateOfString += (("" + month).length < 2 ? "0" : "") + month + "/";
    dateOfString += date.getFullYear();
    return dateOfString;
}

var currentdate = new Date();
var datetime = "Last Sync: ";
datetime += dateToString(currentdate );
datetime += + currentdate.getHours() + ":"
            + currentdate.getMinutes() + ":"
            + currentdate.getSeconds();
