    Thank you for some advices and sorry for my bad english

    HTML code
    HTML Code:
    <form method="post" action="page.php" name="submitto" onSubmit="delete(id)">
    <table>
    <tr><td>First name </td><td><input type="text" name="first_name" class="first_name" value=""></td><td id="first_name" style="color: red;"></td></tr>
    <tr><td>Surname: </td><td><input type="text" name="Surname" class="Surname" value=""></td><td id="Surname" style="color: red;"></td></tr>

    <tr><td colspan="3"><input type="submit" name="send" value="Send" ></td></tr>
    </table>
    </form>
    Javascript for verification filled form
    Code:
    var FormValidation =
    {
      init: function()

        var forms = document.getElementsByTagName("form");
        
        for (var i = 0; i < forms.length; i++)
        {
          Core.addEventListener(forms[i], "submit", FormValidation.submitListener);
        }
      },
    
      rules:
      {
        first_name: /^[a-zA-Z]+$/,
        surname: /^[a-zA-Z]+$/,

        telefone: /^\+?[0-9]{9,12}$/
      },
