转换为树目录结构

// 定义一个函数来构建层级结构
function buildHierarchy(data: any[]): any[]{const hierarchy: any[] = [];const map = new Map<string, any>();console.log('map',map);// 遍历数据，构建 mapdata.forEach(item => {if (!map.has(item.menunamef)) {map.set(item.menunamef, {key:item.categoryidf,label: item.menunamef,children: []});hierarchy.push(map.get(item.menunamef));}if (item.menunames) {const parent = map.get(item.menunamef);if (!parent.children.find(child => child.label === item.menunames)) {parent.children.push({key:item.categoryids,label: item.menunames,children: []});}}if (item.tempname) {const parent = map.get(item.menunamef);const subParent = parent.children.find(child => child.label === item.menunames);if (subParent) {subParent.children.push({label: item.tempname,key: item.tempid});} else {parent.children.push({label: item.tempname,key: item.tempid});}}});return hierarchy;
