fastadmin 树状菜单展开，合并；简要文件管理系统界面设计与实现

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Selectpage
        if ($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
            }
        });
    });
});
