我在验证时遇到问题

我的验证脚本只工作一次，此后不起作用。

$(document).ready(function() {
  function validateCurrency($currency) {
    var currencyFormat = /^[0-9]{1,3}(,[0-9]{3})*\.[0-9]+$/;
    return currencyFormat.test($currency);
  }

  $(document).on("change", "#price_meter", function() {
    if ($("#price_meter").val() === '' && !validateCurrency($("#price_meter").val())) {
      $("#price_meterError").html('لطفا قیمت متری ملک را به تومان وارد کنید.');
    } else {
      $("#price_meterError").html('');
    }
  });
});

jQuery验证仅能解决一次问题
