添加jquery验证后，单击功能不起作用

Question

$(document).on('click', '#dodaj', function(e) {
  $("#addscrap").validate({
    debug: true,
    rules: {
      job: {
        required: true,
        minlength: 3
      },
      keywords: {
        required: true,
        minlength: 5
      }
    },
    messages: {
      job: {
        required: "Podaj nazwę analizy do wykonania",
        minlength: jQuery.validator.format("brakuje {0} znaków!")
      },
      keywords: {
        required: "Podaj słowa kluczowe do analizy",
        minlength: jQuery.validator.format("brakuje {0} znaków!")
      }
    },
    submitHandler: function(form) {
      var data = $("#addscrap").serialize();
      $.ajax({
        data: data,
        type: "post",
        dataType: "JSON",
        url: "views/addscrap.php",
        beforeSend: function(data) {
          document.getElementById('alert').style.display = '';
          $("#alert").text("dodawanie zadania...");
        },
        success: function(data) {
          if (data['error'] == 'exist') {
            document.getElementById('alerterror').style.display = '';
            $('#alerterror').text('Zadanie już istnieje');
            document.getElementById('alert').style.display = 'none';
          } else if (data['error'] == 'add') {
            document.getElementById('alerterror').style.display = 'none';
            $('#alert').text('Dodano zadanie');
            document.getElementById('alert').style.display = '';
            getlist();
          }
        },
        error: function(data) {
          document.getElementById('alerterror').style.display = '';
          $("#alerterror").text("Błąd, spróbuj ponownie");
          document.getElementById('alert').style.display = 'none';
        }
      });
    }
  });
});

当我向这个JS添加jquery验证后，我无法单击按钮#dodaj，当然在控制台中没有错误。有人可以帮我解决这个问题吗？需要在加载函数上添加文档吗？

仅当我删除submitHandler部分时才有效，但是只运行ajax而不对表单进行验证。

           <script>

$( document ).ready(function() {

                $("#addscrap").validate({ 
                      rules: {

                          required: true,
                          minlength: 3
                        },
                        keywords: {
                          required: true,
                          minlength: 5
                        }
                      },
