试试这个

new Date().toTimeString().slice(0, 8);

or

new Date().toTimeString().split(" ")[0];

它应该会起作用。

function getCurrentTime(){
    var date = new Date();
    var hh = date.getHours();
    var mm = date.getMinutes();

    hh = hh < 10 ? '0'+hh : hh; 
    mm = mm < 10 ? '0'+mm : mm;

    curr_time = hh+':'+mm;
    return curr_time;
}

const date = date ().slice(16,21); console.log(日期);

这- - - - - -

var x = new Date(); 
var h = x.getHours(); 
var m = x.getMinutes(); 
var s = x.getSeconds(); 

so-

 x = date
h = hours
m = mins
s = seconds

简单的函数，以获得日期和时间分离，并与时间和日期HTML输入兼容的格式

function formatDate(date) {
  var d         = new Date(date),
      month = '' + (d.getMonth() + 1),
      day   = '' + d.getDate(),
      year  = d.getFullYear();

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return [year, month, day].join('-');
}

function formatTime(date) {
        var hours   = new Date().getHours() > 9 ? new Date().getHours() : '0' + new Date().getHours()
        var minutes = new Date().getMinutes() > 9 ? new Date().getMinutes() : '0' + new Date().getMinutes()

        return hours + ':' + minutes
}

赋值给变量并显示。

time = new Date();

var hh = time.getHours();
var mm = time.getMinutes();
var ss = time.getSeconds() 

document.getElementById("time").value = hh + ":" + mm + ":" + ss;
