试试这个:

var date = new Date();
var hour = date.getHours();
var min = date.getMinutes();

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;
}

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;

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

Try

new Date().toLocaleTimeString().replace("/.*(\d{2}:\d{2}:\d{2}).*/", "$1");

Or

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

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