                            data-bs-target="#myModal" onclick="upDateCF(${l.user_id})" id="upDateCF">
                        更改
                    </button>
                    <script>
                        $("#myModal").modal("hide");
                        function upDateCF(user_id) {
                            // var a=user_id;
                            var xhttp = new XMLHttpRequest();
                            xhttp.open("POST", "/ygUpdateFindById?id="+user_id, true);
                            xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
                            xhttp.send();
                            alert(user_id);
                        }
                    </script>

 jsp页面点击更新按钮向模态框传参数

<button type="button" class="btn btn-primary btn-sm"   data-bs-toggle="modal"data-bs-target="#myModal" onclick="upDateCF(${l.user_id},'${l.name}','${l.age}')" > 更改 </button>

  <script>
 $("#myModal").modal("hide");
      function upDateCF(user_id,name,age) {
                            $('#user_id').val(user_id);
                            $('#name').val(name);
                            $('#age').val(age);
　　　　　　　　　　　　　　}
  </script>

           <!-- 模态框-从菜鸟拿过来的 -->
