后台返回的時間戳轉化為前端的日期

Time(timestamp, separator) {
    let result = "";

    if (timestamp) {

        var d = new Date();
        d.setTime(timestamp);
        var year = d.getFullYear();
        var month = d.getMonth() + 1;
        var day = d.getDate();
        if (month < 10) {
            month = "0" + month;
        }
        if (day < 10) {
            day = "0" + day;
        }
        result = year + separator + month + separator + day;
    }
    return result;

},  

第一個參數是后台傳遞過來的時間戳，第二個參數是字符串形式的分隔符

第二種

formatDateTime(inputTime) {
    let date = new Date(inputTime);
    let y = date.getFullYear();
    let m = date.getMonth() + 1;
    m = m < 10 ? ('0' + m) : m;
    let d = date.getDate();
    d = d < 10 ? ('0' + d) : d;
    let h = date.getHours();
    h = h < 10 ? ('0' + h) : h;
    let minute = date.getMinutes();
    let second = date.getSeconds();
    minute = minute < 10 ? ('0' + minute) : minute;
    second = second < 10 ? ('0' + second) : second;
    return `${y}-${m}-${d}`     //  ${h}:${minute}+':'+second;
},              //時間戳轉化為 yyyy-mm-dd hh:mm
