vue怎么改不了名字（改变原数组字段名称及数组拼接）

let menuData = [ { id: 1, path: '/urlA', title: '一级A', children: [ {pid: 1, id: 11, path: 'urlAA', title: '二级A'}, {pid: 1, id: 12, path: 'urlBB', title: '二级B'} ] }, { id: 2, path: '/urlB', title: '一级B', children: [ {pid: 2, id: 21, path: 'urlCC', title: '二级C'}, {pid: 2, id: 22, path: 'urlDD', title: '二级D'} ] } ] let arr = []; for (let index = 0; index < menuData.length; index ) { let childData = menuData[index].children; let child = []; for(let key = 0 ; key < childData.length; key ){ child.push({pid: childData[key].pid, id: childData[key].id,name: childData[key].title}); } arr.push({id: menuData[index].id,name: menuData[index].title,child: child}) } console.log(arr)

输出结果如图:
