Date.toLocaleTimeString()选项

Date.toLocaleTimeString()函数可以接收一个选项参数来格式化输出

以下是一些可用的选项

new Date().toLocaleTimeString([], { timeStyle: "full" })   // 4:43:58 AM Pacific Standard Time
new Date().toLocaleTimeString([], { timeStyle: "long" })   // 4:43:58 AM PST
new Date().toLocaleTimeString([], { timeStyle: "medium" }) // 4:43:58 AM
new Date().toLocaleTimeString([], { timeStyle: "short" })  // 4:43 AM

或者你可以用这些值指定小时、分钟和秒的表示形式:

“数字”(例如，1) “2位数”(例如，01)

new Date().toLocaleTimeString([], { hour: '2-digit', minute: "2-digit" }) 
// 04:43 AM

或者使用hour12: true或false设置12小时时间

更多细节请看 Date.toLocaleTimeString()参数 Intl.DateTimeFormat()选项

var hours = date.getHours();
        var minutes = date.getMinutes();
        var ampm = hours >= 12 ? 'pm' : 'am';
        hours = hours % 12;
        hours = hours ? hours : 12; // the hour '0' should be '12'
        minutes = minutes < 10 ? '0'+minutes : minutes;
        var strTime = hours + ':' + minutes + ' ' + ampm;
        console.log(strTime);
        $scope.time = strTime;

        date.setDate(date.getDate()+1);
        month = '' + (date.getMonth() + 1),
        day = '' + date.getDate(1),
        year = date.getFullYear();
        if (month.length < 2) month = '0' + month;
        if (day.length < 2) day = '0' + day;
        var tomorrow = [year, month, day].join('-');
        $scope.tomorrow = tomorrow;

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;

var today = new Date();  //gets current date and time
var hour = today.getHours();         
var minute = today.getMinutes();
var second = today.getSeconds();
