1.概述

本節實現 刪除賬戶 功能，刪除執行前需要用戶確認。

2.後端代碼實現

AuthManagerMapper.xml 修改

修改 delete 語句，將查詢條件改為 userKey，代碼如下：

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

ManagerController 修改

增加 delete 方法，代碼如下：

@RequestMapping(value = "delete/{userKey}", method = RequestMethod.GET)
public String delete(@PathVariable String userKey, RedirectAttributes redirectAttributes) {
    if (StringUtils.isBlank(userKey)) {
        redirectAttributes.addFlashAttribute("baseResult", BaseResult.fail("參數為空"));
        return "redirect:/auth/manager/list";
    }
    AuthManager authManager = authManagerService.getByUserKey(userKey);
    if (authManager == null) {
        redirectAttributes.addFlashAttribute("baseResult", BaseResult.fail("數據不存在"));
        return "redirect:/auth/manager/list";
    }
    authManagerService.delete(userKey);
    redirectAttributes.addFlashAttribute("baseResult", BaseResult.success(String.format("賬戶[%s]已被成功刪除", authManager.getUserName())));
    return "redirect:/auth/manager/list";
}

3.前端頁面實現

修改視圖 manager_list.jsp 文件，將要達到的效果如下：

刪除按鈕

<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>

彈框佈局

<div class="modal fade" id="modal-operate-confirm">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h4 class="modal-title">操作確認</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>操作後不可恢復，確定嗎？</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">確定</button>
            </div>
        </div>
        <!-- /.modal-content -->
    </div>
    <!-- /.modal-dialog -->
</div>
<!-- /.modal -->

彈框控制腳本

$('#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
    })
})

4.實例源碼
