一，菜单合并效果图

源文件参考：fastadmin 子级菜单展开合并、分类父级归纳 - FastAdmin问答社区

php服务端：

public function _initialize()
{parent::_initialize();$this->model = new \app\admin\model\auth\Filetype;$this->adminModel = model('Admin');//重点：转成树状结构$tree = Tree::instance();$tree->init(collection($this->model->order('weigh desc,id desc')->select())->toArray(), 'pid');$this->categorylist = $tree->getTreeList($tree->getTreeArray(0), 'type_name');$categorydata = [0 => ['id' => '0', 'type_name' => __('None')]];foreach ($this->categorylist as $k => $v) {$categorydata[$v['id']] = $v;}$this->view->assign("parentList", $categorydata);$auth_group_id = $this->auth->getGroupIds();$this->view->assign("auth_group_id", $auth_group_id[0]);}public function index()
{//当前是否为关联查询$this->relationSearch = true;//设置过滤方法$this->request->filter(['strip_tags', 'trim']);if ($this->request->isAjax()) {//如果发送的来源是Selectpage，则转发到Selectpageif ($this->request->request('keyField')) {return $this->selectpage();}$list = $this->categorylist;$total = count($list);foreach ($list as $key=>$row) {$list[$key]['admin'] = $this->adminModel->field('username,nickname,email,mobile')->where('id',$row['create_admin_id'])->find();}$result = array("total" => $total, "rows" => $list);return json($result);}return $this->view->fetch();
}

js文件：backend 文件夹下找到该模块下的文件

// 初始化表格
table.bootstrapTable({url: $.fn.bootstrapTable.defaults.extend.index_url,pk: 'id',sortName: 'weigh',escape: false,columns: [[{checkbox: true},{field: 'id', title: __('Id')},{field: 'type_name', title: __('Type_name'), align: 'left', formatter:function (value, row, index) { return value.toString().replace(/(&|&)nbsp;/g, ' '); } },{field: 'createtime', title: __('Createtime'), operate:'RANGE', addclass:'datetimerange', autocomplete:false, formatter: Table.api.formatter.datetime},{field: 'updatetime', title: __('Updatetime'), operate:'RANGE', addclass:'datetimerange', autocomplete:false, formatter: Table.api.formatter.datetime},{field: 'weigh', title: __('Weigh'), operate: false},{field: 'create_admin_id', title: __('Create_admin_id')},{field: 'admin.username', title: __('创建者用户名')},{field: 'admin.nickname', title: __('创建者昵称')},{field: 'admin.email', title: __('Admin.email')},{field: 'admin.mobile', title: __('Admin.mobile')},{field: 'id', title: '展开', operate: false, formatter: Controller.api.formatter.subnode},{field: 'operate', title: __('Operate'), table: table, events: Table.api.events.operate, formatter: Table.api.formatter.operate}]],pagination: false,//隐藏分页search: false,//隐藏搜索框commonSearch: false,//隐藏搜索按钮showToggle: false,//表格视图两种模式showColumns: false,//隐藏列showExport: false,//隐藏导出
});//核心三个地方
//{field: 'type_name', title: __('Type_name'), align: 'left', formatter:function (value, row, index) { return value.toString().replace(/(&|&)nbsp;/g, ' '); } },
//{field: 'operate', title: __('Operate'), table: table, events: Table.api.events.operate, formatter: Table.api.formatter.operate}
/*
pagination: false,//隐藏分页
search: false,//隐藏搜索框
commonSearch: false,//隐藏搜索按钮
showToggle: false,//表格视图两种模式
showColumns: false,//隐藏列
showExport: false,//隐藏导出
*/

同样在index方法里面：

// 为表格绑定事件：这个是原有的，下面的是全部新增的
Table.api.bindevent(table);  //当内容渲染完成后
table.on('post-body.bs.table', function (e, settings, json, xhr) {//默认隐藏所有子节点$("a.btn[data-id][data-pid][data-pid!=0]").closest("tr").hide();// $(".btn-node-sub.disabled").closest("tr").hide();//显示隐藏子节点$(".btn-node-sub").off("click").on("click", function (e) {var status = $(this).data("shown") ? true : false;$("a.btn[data-pid='" + $(this).data("id") + "']").each(function () {$(this).closest("tr").toggle(!status);});$(this).data("shown", !status);return false;});//点击切换/排序/删除操作后刷新左侧菜单$(".btn-change[data-id],.btn-delone,.btn-dragsort").data("success", function (data, ret) {Fast.api.refreshmenu();return false;});});
//批量删除后的回调
$(".toolbar > .btn-del,.toolbar .btn-more~ul>li>a").data("success", function (e) {Fast.api.refreshmenu();
});
//展开隐藏一级
$(document.body).on("click", ".btn-toggle", function (e) {$("a.btn[data-id][data-pid][data-pid!=0].disabled").closest("tr").hide();var that = this;var show = $("i", that).hasClass("fa-chevron-down");$("i", that).toggleClass("fa-chevron-down", !show);$("i", that).toggleClass("fa-chevron-up", show);$("a.btn[data-id][data-pid][data-pid!=0]").not('.disabled').closest("tr").toggle(show);$(".btn-node-sub[data-pid=0]").data("shown", show);
});
//展开隐藏全部
$(document.body).on("click", ".btn-toggle-all", function (e) {var that = this;var show = $("i", that).hasClass("fa-plus");$("i", that).toggleClass("fa-plus", !show);$("i", that).toggleClass("fa-minus", show);$(".btn-node-sub.disabled").closest("tr").toggle(show);$(".btn-node-sub").data("shown", show);
});

api下增加

api: {formatter: {subnode: function (value, row, index) {return '<a href="javascript:;" data-toggle="tooltip" title="' + __('展开/收起') + '" data-id="' + row.id + '" data-pid="' + row.pid + '" class="btn btn-xs '+ (row.haschild == 1 || row.ismenu == 1 ? 'btn-success' : 'btn-default disabled') + ' btn-node-sub"><i class="fa fa-sitemap"></i></a>';}},bindevent: function () {Form.api.bindevent($("form[role=form]"));}
}

注意：上下级结构需要用pid进行关联

二，文件系统左右展示，点击左侧菜单右侧显示出对应文件

index: function () {
// 初始化表格参数配置
Table.api.init({extend: {index_url: 'auth/filelist/index' + location.search,multi_url: 'auth/filelist/multi',import_url: 'auth/filelist/import',add_url: 'auth/filelist/add',dragsort_url:'',table: 'filelist',}
});var table = $("#table");function dir_address($dir_id){//获取当前文件操作权限$.ajax({url: "auth/filelist/get_dir_child", //请求接口type: "post",dataType: "json",data: {"dir_id": $dir_id}, //请求参数success: function (effect) {if(effect.code == 1){var data = effect.data.child_list;var output_str = '';for(var i=0;i<data.length;i++){output_str += '<li><a href="javascript:;" class="child_nav" dataid="'+data[i].id+'">';output_str += '<img src="/assets/img/folder.svg">';output_str += data[i].type_name;output_str += '</a><span>'+data[i].updatetime_text+'</span></li>';}$(".jstree-default").html(output_str);//获取当前所在位置var parents = effect.data.parents;var address = '当前位置：<a href="">全部</a>';for(var i=0;i<parents.length;i++){address += ' &gt; <a href="javascript:;" class="child_nav" dataid="'+parents[i].id+'">'+parents[i].type_name+'</a>'}$("#address").html(address);}}})
}//联动主要靠下面这个，选左侧菜单后，将选中的值赋给右侧，并触发提交事件
$(function(){$('body').on('click','.child_nav',function(){$dir_id = $(this).attr('dataid');//这个根据实际表格的id进行赋值，不仅要赋值隐藏域，也需要赋值给下拉框$("#myTabContent .form-commonsearch input[name='type_id-operate']").val($dir_id);$("#myTabContent .form-commonsearch select[name='type_id']").val($dir_id);$(".form-commonsearch").submit();$("#dir_id").val($dir_id);dir_address($dir_id);});
})$(function(){$('body').on('click','.add-dir-file',function(){$dir_id = $("#dir_id").val();Fast.api.open('auth/filelist/add?dir_id='+$dir_id, __('添加'),{end:function(){dir_address($dir_id); //获取当前位置}});});
});
