日期+三位近似随机的数，并且利用localStorage防止重复。。

function fnAutoAlias() {
  if (document.forms["edit"].edtAlias.value == "") {
    const vDate = new Date();
    const year = vDate.getFullYear();
    const month = vDate.getMonth() + 1;
    const day = vDate.getDate();
    const vNWE = vDate.valueOf() / 233;
    const strAlias = [
      year.toString() +
        ("0" + month.toString()).substr(-2, 2) +
        ("0" + day.toString()).substr(-2, 2),
      vNWE.toString().substr(-3, 3),
    ];
    // console.log(strAlias);
    const lsKeyCurDay = "InputMove_curDay";
    const lsKeyUsedList = "InputMove_UsedList";
    if (
      !localStorage[lsKeyCurDay] ||
      localStorage[lsKeyCurDay] !== strAlias[0]
    ) {
      localStorage[lsKeyCurDay] = strAlias[0];
      localStorage[lsKeyUsedList] = "";

      localStorage[lsKeyUsedList].indexOf(strAlias[1]) > -1
