Fastadmin 子级菜单展开合并,分类父级归纳

Fastadmin 子级菜单展开合并,分类父级归纳_第1张图片

这里踩过一个坑,fastadmin默认的展开合并预定义处理的变量是pid。

所以建表时父级id需要是pid;

当然不是pid也没关系,这里以cat_id为例,多加一步处理一样能实现。

废话少说上代码:

首先在控制器,

引用:use fast\Tree;

自动调取函数 _initialize 内添加以下代码:

cat_id 我重命名成pid了。本身是pid的忽略不计。

public function _initialize()
    {
        parent::_initialize();
        $this->model = new \app\admin\model\classification\Classification;

        $tree = Tree::instance();
        $tree->init(collection($this->model->field('*,cat_id as pid')->order('id desc')->select())->toArray(), 'pid');
        $this->categorylist = $tree->getTreeList($tree->getTreeArray(0), 'name');

        $categorydata = [0 => ['name' => __('None')]];
        foreach ($this->categorylist as $k => &$v) {
            $categorydata[$v['id']] = $v;
        }

        $this->view->assign("parentList", $categorydata);

    }

复制控制器index方法:

 public function index()
    {
        if ($this->request->isAjax()) {
            $list = $this->categorylist;
            $total = count($this->categorylist);
            $result = array("total" => $total, "rows" => $list);
            return json($result);
        }
        return $this->view->fetch();
    }

接下来找到 js 文件:

目录:public\assets\js\backend\classify.js

注意:

原name:{field: 'name', title: __('Name')},

替换为:

{field: 'name', title: __('Name'), align: 'left', formatter:function (value, row, index) { return value.toString().replace(/(&|&)nbsp;/g, ' '); } },

添加一列展开合并的按钮

{
    field: 'id',
    title: '',
    operate: false,
    formatter: Controller.api.formatter.subnode
},

整段js示例:

// 初始化表格
table.bootstrapTable({
    url: $.fn.bootstrapTable.defaults.extend.index_url,
    pk: 'id',
    sortName: 'id',
    escape: false,
    columns: [
        [
            {checkbox: true},
            {field: 'id', title: __('Id')},
            {field: 'pid', title: __('Pid')},
            {
                field: 'name', title: __('Name'), align: 'left', formatter: function (value, row, index) {
                        return value.toString().replace(/(&|&)nbsp;/g, ' ');
                    }
            },
            {
                field: 'id',
                title: '',
                operate: false,
                formatter: Controller.api.formatter.subnode
            },
            {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: '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
    rowAttributes: function (row, index) {
        if (this.totalRows > 500) {
            return row.pid == 0 ? {} : {style: "display:none"};
        }
        return row.haschild == 1 || row.pid ? {} : {style: "display:none"};
    }
});

注意 escape: false, 属性

还是在js文件, table.bootstrapTable下追加以下代码:

// 为表格绑定事件
Table.api.bindevent(table);

//表格内容渲染前
table.on('pre-body.bs.table', function (e, data) {
    var options = table.bootstrapTable("getOptions");
    options.escape = true;
});

// 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);
});

还是js文件,下面api 替换为:

api: {
    formatter: {
        subnode: function (value, row, index) {
        return '';
        }
    },
    bindevent: function () {
        $(document).on('click', "input[name='row[pid]']", function () {
            var name = $("input[name='row[name]']");
            var ismenu = $(this).val() == 1;
            name.prop("placeholder", ismenu ? name.data("placeholder-menu") : name.data("placeholder-node"));
            $('div[data-type="menu"]').toggleClass("hidden", !ismenu);
        });

        $("input[name='row[ismenu]']:checked").trigger("click");

        var iconlist = [];

        var iconfunc = function () {
            Layer.open({
                type: 1,
                area: ['99%', '98%'], //宽高
                content: Template('chooseicontpl', {iconlist: iconlist})
            });
        };
        Form.api.bindevent($("form[role=form]"), function (data) {
            Fast.api.refreshmenu();
        });
        $(document).on('change keyup', "#icon", function () {
            $(this).prev().find("i").prop("class", $(this).val());
        });
        $(document).on('click', ".btn-search-icon", function () {
            if (iconlist.length == 0) {
                $.get(Config.site.cdnurl + "/assets/libs/font-awesome/less/variables.less", function (ret) {
                    var exp = /fa-var-(.*):/ig;
                    var result;
                    while ((result = exp.exec(ret)) != null) {
                        iconlist.push(result[1]);
                    }
                    iconfunc();
                });
            } else {
                iconfunc();
            }
        });
        $(document).on('click', '#chooseicon ul li', function () {
            $("input[name='row[icon]']").val('fa fa-' + $(this).data("font")).trigger("change");
            Layer.closeAll();
        });
        $(document).on('keyup', 'input.js-icon-search', function () {
            $("#chooseicon ul li").show();
            if ($(this).val() != '') {
                $("#chooseicon ul li:not([data-font*='" + $(this).val() + "'])").hide();
            }
        });
    }

}
