选中复选框的行表中的表单中没有复选框数据

Question

In a table, each row contains a checkbox in an unique form like this:

<td class="d-inline-block col-2">
        <div class="form-check">
          <form action="/slider-update/1" method="post" id="check-1">
            <input type="hidden" name="csrfmiddlewaretoken" value="uDIiSPShbE3R2COQDI0qE4SlJGiqsQy8CQ2nQ0jllibaOqH6YsU8TtL7Xy0pF8sI">
            <input class="form-check-input position-static" type="checkbox" id="1" value="is_active" aria-label="...">
          </form>
        </div>
 </td>

Each form is identified with an id formatted with a pk (here: "check-1"). Despite all these clear informations, I can't get my form!

Here is my javascript code:

    $(document).on('click', 'form', function () {
      var rpk = $(this).attr("id");
      var url = $(this).attr("action");
      var form = $('#' + rpk);
      $.post(url, form.serializeArray())
          .done(function (data) {
              alert( data );
          });
  }); 

I get the correct form but it contains only the token, nothing related to the checkbox.

You need to set name attribute to your checkbox. jQuery document here serializeArray

that's change your code like this:

 <input class="form-check-input position-static" type="checkbox" id="1" name= "checkbox-1" value="is_active" aria-label="...">

also in your JavaScript code. Don't need to do

var form = $('#' + rpk);

you can just use

$(this).serializeArray()

that's :

    $(document).on('click', 'form', function () {
      var url = $(this).attr("action");
      $.post(url, $(this).serializeArray())
          .done(function (data) {
              alert( data );
          });
  });
