如何在弹框中获取 Foreach 循环中的 ID 值并将其作为链接参数传递？

<div id="mymodal" class="modal fade" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">设置</h4>
      </div>
      <div class="modal-body">
        <form id="setupform">
          <input type="hidden" id="user_id">
        </form>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
        <button type="button" class="btn btn-primary" id="setupconfirmbutton">确认</button>
      </div>
    </div>
  </div>
</div>

$(document).ready(function() {
  $(".setup").on("click", function() {
    var user_id = $(this).data("uid");
    $("#user_id").val(user_id);
    $("#mymodal").modal("show");
  });
});

$("#setupConfirmButton").on("click", function() {
  var user_id = $("#user_id").val();
  window.location.href = "/Index/jxMoneyToBank?uid=" + user_id;
});
