js時間格式轉換以及倒計時（天-時-分-秒）

給出的時間格式為 "/Date(1586095959200)/"

 

function ChangeDateFormat(cellval) {//輸出格式為"2020-04-05"
    var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/", ""), 10));
    var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
    var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
    return date.getFullYear() + "-" + month + "-" + currentDate;
}

function ChangeDateFormatseconds(cellval) {//輸出格式為"2020-04-05 22:12:39"
    var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/", ""), 10));
    var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
    var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
    var hours=date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
    var minutes=date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
    var seconds=date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();
    return date.getFullYear() + "-" + month + "-" + currentDate+' '+hours+':'+minutes+':'+seconds;
}

function datazhou(cellval) {//輸出格式為"04月05日 周日 22:12"
    var weekday=["周日","周一","周二","周三","周四","周五","周六"];
    var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/", ""), 10));
    var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
