js修改日期格式

function time(time) {
            return time.substr(0, 19).replace('T', ' ');
        }
//修改日期的格式
function ChangeDateFormat(cellval) {
    var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/", ""), 10));
    //getMonth()從0開始算
    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;
}
//去掉時分秒
function DropSFM(time_str) {
    var temp = new Date(time_str);
    return temp.getFullYear() + "-" + (temp.getMonth() + 1) + "-" + temp.getDate();
}
