javascript - javascript moment.js脚本无法正常运行

下面的代码：if（exDate.isBefore（今天）||！exDate）->！exDate代码不起作用。谁能帮我？我正在尝试根据到期日期计算ef FEE。 http://verlager.com/account-pure.php该代码必须包含**成员>“” **

function calcEntryFee( elem ) {
var idx, member, exDate, today, fee;

elem = elem || {};
if ( /^[PEMX](\d+)$/.test( elem.id ) ) {
    idx = RegExp.$1;
} else {
    return false;
}

member = getMemberData( jQuery( '#P' + idx ).val() );
mmfee = parseFloat( jQuery( '#M' + idx ).val() );
//exDate = moment( member.Expires, 'YYYY.MM.DD' );
exDate = member && member.Expires && member.Expires !== '' ? moment( member.Expires, 'YYYY.MM.DD' ) : null
today = moment();
fee = '';

if ( (!exDate || !exDate.isValid() || exDate.isBefore( today )) && (member.Name > '')) {fee = 5;} // this just doesn't work.

if (!exDate)
{
    fee = 5;
} else if ( exDate.isSameOrAfter( today ) ) {
    fee = 3;
} else if ( ! member.Expires && mmfee > 0 ) {
    fee = 0;
}

// Updates the entry fee input value.
jQuery( '#E' + idx ).val( fee );

return fee;
}

最佳答案

我有这个确切的问题。我最终使用了moment-range。根据您的代码示例，也许您可​​以像这样检查过期时间：

import Moment from 'moment'
import { extendMoment } from 'moment-range'

const moment = extendMoment(Moment)

export default (expires) => {
  const momentExpires = moment(expires, 'YYYY.MM.DD')
  const now = moment()

  const expirationCheck = moment.range(now.format(), momentExpires.format())

  return {
    expired: expirationCheck.valueOf() < 0
  }
}
