推荐使用： 通过截取函数操作,在拼接的时候需要加个空格，不然会有问题

//js获取当前的时分秒 
        let myDate = new Date();
        let str = myDate.toTimeString(); //"10:55:24 GMT+0800 (中国标准时间)"
        let timeStr = str.substring(0,8); //  '10:55:24'


//js获取当前的时分秒
        let myDate = new Date();
        let str = myDate.toTimeString();
        let timeStr = str.substring(0,8);

        let temp1 = startDate + ' '+ timeStr;
        let temp2 = startDate +' ' + timeStr;

        sendData['begin_time'] = (new Date(temp1).getTime() / 1000).toFixed(0);
        sendData['end_time'] = (new Date(temp2).getTime() / 1000).toFixed(0);

需要手动补零

//js获取当前的时分秒
        let myDate = new Date();
        let h = myDate.getHours(); // 获取当前小时数(0-23)
        let m = myDate.getMinutes(); // 获取当前分钟数(0-59)
        let s = myDate.getSeconds();// 获取当前秒数(0-59)
        let timeStr = h + ':' + 'm' + 's';

输出： "10:55:24" || "10:55:1 不会自动补零

前台html页面日期格式化： 

{{ dateTime | date:'yyyy-MM-dd HH:mm:ss'}}

{{ dateTime | date:'medium' }}

{{ dateTime | date:'short' }}

{{ dateTime | date:'fullDate' }}

{{ dateTime | date:'longDate' }}

{{ dateTime | date:'mediumDate' }}

{{ dateTime | date:'shortDate' }}

{{ dateTime | date:'mediumTime' }}

{{ dateTime | date:'shortTime' }}
