参考

用vue {{}}方式 显示的Data字符串 是UTC

SQL Server DateTIme => “YYYY-MM-DD hh:mm:ss.xxx”

function dateToMssql(datetime) {
  let year = datetime.getFullYear(),
    month = datetime.getMonth() + 1,
    date = datetime.getDate(),
    hour = datetime.getHours(),
    minutes = datetime.getMinutes(),
    second = datetime.getSeconds(),
    ms = datetime.getMilliseconds();
  if (month < 10) {
    month = "0" + month;
  }
  if (date < 10) {
    date = "0" + date;
  }
  if (hour < 10) {
    hour = "0" + hour;
  }
  if (minutes < 10) {
    minutes = "0" + minutes;
  }
  if (second < 10) {
    second = "0" + second;
  }
  return (
    year +
    "-" +
    month +
    "-" +
    date +
    " " +
    hour +
    ":" +
    minutes +
    ":" +
    second +
    "." +
    ms
  );
}

更加通用的方法

function dateFormat(fmt, date) {
  let ret;
  const opt = {
    "Y+": date.getFullYear().toString(),        // 年
    "m+": (date.getMonth() + 1).toString(),     // 月
    "d+": date.getDate().toString(),            // 日
    "H+": date.getHours().toString(),           // 时
    "M+": date.getMinutes().toString(),         // 分
    "S+": date.getSeconds().toString(),         // 秒
    "q+": Math.floor((date.getMonth() + 3) / 3), //季度   
    "s": date.getMilliseconds()             //毫秒  
  };
  for (let k in opt) {
    ret = new RegExp("(" + k + ")").exec(fmt);
    if (ret) {
      fmt = fmt.replace(ret[1], (ret[1].length == 1) ? (opt[k]) : (opt[k].padStart(ret[1].length, "0")))
    };
  };
  return fmt;
}
