这是组成树形结构的第二种方法，———–下面是代码
const TreeData=[ { id:1, parentId:-1, guid:"5bc9ec72-b9cd-4a85-a04e-56260f368d9d", parentGuid:"00000000-0000-0000-0000-000000000000", name:"南充分行", }, { id:2, parentId:1, guid:"fd16c3a8-321c-47fd-8121-4c3756449932", parentGuid:"5bc9ec72-b9cd-4a85-a04e-56260f368d9d", name:"南充分行下的1", }, { id:3, parentId:1, guid:"1200819a-5c12-4851-9d05-c2e8854c2fe0", parentGuid:"5bc9ec72-b9cd-4a85-a04e-56260f368d9d", name:"南充分行下的2", }, { id:4, parentId:-1, guid:"d52bad43-12ad-4533-ad24-ea8be67d2713", parentGuid:"00000000-0000-0000-0000-000000000000", name:"成都分行", }, { id:5, parentId:4, guid:"23d186aa-30e9-4d9b-abac-62e383124576", parentGuid:"d52bad43-12ad-4533-ad24-ea8be67d2713", name:"成都分行下的1", }, { id:6, parentId:4, guid:"b3c787b2-d954-48d8-a9fc-43be666c396b", parentGuid:"d52bad43-12ad-4533-ad24-ea8be67d2713", name:"成都分行下的2", }, { id:7, parentId:6, guid:"db1b2460-46f6-43c8-8c20-737322fdaa10", parentGuid:"b3c787b2-d954-48d8-a9fc-43be666c396b", name:"成都分行2下的1", }, { id:8, parentId:6, guid:"427e12dc-7fb2-4939-aae9-6c8e1511f3e2", parentGuid:"b3c787b2-d954-48d8-a9fc-43be666c396b", name:"成都分行2下的1", },上面的数据也是一种树形结构，父节点的id等于子节点的parentI的，父节点的guid等于子节点的parentGuid
const parent=[ { id:1, name:"报警设备1", guid:"3cf6a90a-94c1-49a3-8ab0-c6acc6fc9a16", }, { id:2, name:"报警设备2", guid:"c20f6343-8a09-400e-8405-d5b0b8353cf6", }, { id:3, name:"报警设备3", guid:"e1f3420d-dced-49a1-87a6-c976e1a8bc13", }, ]; const children=[ { id:1, name:"报警输入1", guid:"b3e445ac-1742-4cb3-84cb-bfce9f7e9333", deviceId:1, }, { id:2, name:"报警输入2", guid:"2f846f3d-d57e-48a5-aa9e-c2c9d164c024", deviceId:1, }, { id:3, name:"报警输入3", guid:"d4aa49b7-13b9-4200-8c7a-96fee44797ea", deviceId:1, }, { id:4, name:"报警输入4", guid:"90a288e9-aca5-404f-b767-c4ee54f20368", deviceId:1, }, { id:5, name:"报警输入5", guid:"b15a0c29-aa55-4c3c-a298-f59beaf98535", deviceId:1, }, ];
