使用jQuery重新排序Div，然后使用form post提交

<script src="https://cdn.jsdelivr.net/jquery/3.6.0/jquery.min.js"></script>

<div id="div1">Div 1</div>
<div id="div2">Div 2</div>
<div id="div3">Div 3</div>

$(function() {
  $("div").sortable();
});

<form id="myForm" action="submit.php" method="post">
  <input type="hidden" name="divOrder" id="divOrder">
  <input type="submit" value="Submit">
</form>

$(function() {
  $("div").sortable({
    update: function(event, ui) {
      var divOrder = $(this).sortable("toArray");
      $("#divOrder").val(divOrder.join(","));
    }
  });

  $("#myForm").submit(function() {
    var divOrder = $("div").sortable("toArray");
    $("#divOrder").val(divOrder.join(","));
    return true;
  });
});
