前端项目实战叁佰伍拾伍react-admin和material ui-处理形成树状数据结构1

 if(data !== undefined) {
            let temp: ITreeData[] = [{key: '0', title: '工厂管理', children: new Array<ITreeData>()}];

            //向从数据库查询到的数据中添加Tree结构所需要的字段，key使用id，title使用name;
            data.forEach(it => {
                it['key'] = `${it.id}`;
                it['title'] = it.name;
                it['isPlant'] = true;
                it.children && it.children.forEach((item: any)=>{
                    item['key'] = `${it.id}-${item.id}`;
                    item['title'] = item.name
                    item['isLine'] = true;
                })
            });

            temp[0].children = data;
            setTreeData(temp);
        }
