1.概述

本节实现 删除账户 功能，删除执行前需要用户确认。

2.后端代码实现

AuthManagerMapper.xml 修改

修改 delete 语句，将查询条件改为 userKey，代码如下：

<delete id="delete">
    DELETE FROM auth_manager WHERE user_key = #{userKey}
</delete>

ManagerController 修改

增加 delete 方法，代码如下：

@RequestMapping(value = "delete/{userKey}", method = RequestMethod.GET)
public String delete(@PathVariable String userKey, RedirectAttributes redirectAttributes) {
    if (StringUtils.isBlank(userKey)) {
        redirectAttributes.addFlashAttribute("baseResult", BaseResult.fail("参数为空"));
        return "redirect:/auth/manager/list";
    }
    AuthManager authManager = authManagerService.getByUserKey(userKey);
    if (authManager == null) {
        redirectAttributes.addFlashAttribute("baseResult", BaseResult.fail("数据不存在"));
        return "redirect:/auth/manager/list";
    }
    authManagerService.delete(userKey);
    redirectAttributes.addFlashAttribute("baseResult", BaseResult.success(String.format("账户[%s]已被成功删除", authManager.getUserName())));
    return "redirect:/auth/manager/list";
}

3.前端页面实现

修改视图 manager_list.jsp 文件，将要达到的效果如下：

删除按钮

<button type="button" class="btn btn-danger btn-sm" data-toggle="modal" data-target="#modal-operate-confirm" data-whatever="${authManager.userKey}"><i class="fas fa-trash"></i></button>

弹框布局

<div class="modal fade" id="modal-operate-confirm">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h4 class="modal-title">操作确认</h4>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
            <div class="modal-body">
                <p>操作后不可恢复，确定吗？</p>
            </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">确定</button>
            </div>
        </div>
        <!-- /.modal-content -->
    </div>
    <!-- /.modal-dialog -->
</div>
<!-- /.modal -->

弹框控制脚本

$('#modal-operate-confirm').on('show.bs.modal', function (event) {
    let trigger = $(event.relatedTarget)
    let userKey = trigger.data('whatever')
    let modal = $(this)
    let ok = modal.find('.modal-footer button')[1]
    $(ok).click(function(e) {
        location.href = '/auth/manager/delete/' + userKey
    })
})
