大家好！如果你能帮我解决这个我无法解决的问题，我将不胜感激。我想用sweetalert删除mysql数据库中的一条记录。就像这张照片：https://imgur.com/bstkuvx
所发生的事情是，当我在“确定”的sweetalert框中单击时，不会删除记录。欢迎所有回复。这个项目是在springboot中使用controller（modelandview）、html和javascript（sweetalert）。非常感谢任何能帮助我的人。维托。mip@gmail.com
控制器.java

@RequestMapping("delete.htm")
public ModelAndView Delete(HttpServletRequest request) {
    id = Integer.parseInt(request.getParameter("id"));
    String sql = "delete from escola where id=" + id;
    this.jdbcTemplate.update(sql);
    return new ModelAndView("redirect:/escolas.htm");
}

html格式

<c:forEach var="bd" items="${lista}">
                            <tr class="text-center">
                                <td style="text-align:left; font-size:10px">${bd.escola}</td>                                      
                                <td style="text-align:left; font-size:10px">${bd.localidade}</td>
                                <td style="text-align:left; font-size:10px">${bd.email}</td>
                                <td style="text-align:left; font-size:10px">${bd.telefone}</td>
                                <td style="text-align:left; font-size:10px">${bd.ano_lectivo}</td>
                                <td style="text-align:left; font-size:10px">${bd.obs}</td>
                                <td style="text-align:left; font-size:10px">${bd.registo}</td>

                                <td class="d-flex">
                                <a style="font-size:10px" href="editar.htm?id=${bd.id}" class="btn btn-warning">Editar</a>

                                <input class="deleteid" type="hidden" value="${bd.id}">
                                <a class="elimina_registo btn btn-danger" style="font-size:12px;">Eliminar</a>
                                </td>
                            </tr>
                        </c:forEach>

javascript（sweetalert）
