C#車牌校驗

public static bool IsVehicleNumber(string vehicleNumber)
{
    bool result = false;
    if (vehicleNumber.Length == 7){
      string express = @"^[京津滬渝冀豫雲遼黑湘皖魯新蘇浙贛鄂桂甘晉蒙陝吉閩貴粵青藏川寧瓊使領A-Z]{1}[A-Z]{1}[A-Z0-9]{4}[A-Z0-9掛學警港澳]{1}$";
      result = Regex.IsMatch(vehicleNumber, express);
    }
    return result;
}

數字和小數點

<input type="text" class="form-control" maxlength="10" id="price-val" style="width: 100px;" onkeyup="this.value=this.value.replace(/[^0-9\.]/g,'')" >

只能爲數字 長度只能爲4或者6

^(?:\d{4}|\d{6})$
