弹窗中如何获取foreach循环的ID值并传递给链接？

<input type="hidden" id="user_id" value="<?php echo $val['c']['user_id']; ?>" />

<a href="javascript:void(0);" class="setup" data-uid="<?php echo $val['c']['user_id']; ?>">［取现］</a>

var uid = $(this).data('uid');

window.open("/Index/jxMoneyToBank?uid=" + uid, '_blank');
