每天都能遇到奇奇怪怪的问题哈
修改前的数据
let HouChen = [
{
name: '羽神', 年龄: 13, sex: '女', userList: [{
id: 1, Z_name: '钢铁侠' }] },
{
name: '少主', 年龄: 14, sex: '女', userList: [{
id: 2, Z_name: '蜘蛛侠' }] },
{
name: '刘备', 年龄: 15, sex: '女', userList: [{
id: 3, Z_name: '绿巨人' }] },
{
name: '关于', 年龄: 17, sex: '女', userList: [{
id: 4, Z_name: '美国队长' }] },
{
name: '老威', 年龄: 15, sex: '男', userList: [{
id: 5, Z_name: '冲锋侠' }] },
{
name: '村长', 年龄: 13, sex: '女', userList: [{
id: 6, Z_name: '峡谷先锋' }] }
]
- 通过forEach遍历
function convertKey(arr, key) {
let newArr = [];
HouChen.forEach((item, index) => {
let newObj = {
};
for (var i = 0; i < key.length; i++) {
newObj[key[i]] = item[Object.keys(item)[i]]
}
newArr.push(newObj);
})
return newArr;
}
let HouChen2 = convertKey(HouChen, ['person', 'age', 'sex', 'children',]);
修改后的数据
{
person: '羽神', age: 13, sex: '女', children: [{
id: 1, Z_name: '钢铁侠' }] },
{
person: '少主', age: 14, sex: '女', children: [{
id: 2, Z_name: '蜘蛛侠' }] },
{
person: '刘备', age: 15, sex: '女', children: [{
id: 3, Z_name: '绿巨人' }] },
{
person: '关于', age: 17, sex: '女', children: [{
id: 4, Z_name: '美国队长' }] },
{
person: '老威', age: 15, sex: '男', children: [{
id: 5, Z_name: '冲锋侠' }] },
{
person: '村长', age: 13, sex: '女', children: [{
id: 6, Z_name: '峡谷先锋' }] }
- 通过递归 可以修改对象数组中对象的属性名
function copyTransFun(arr) {
arr.forEach((item, value) => {
if (item.name) {
item.person = item.name;
delete item.name;
}
if (item.Z_name) {
item.Z_person = item.Z_name;
delete item.Z_name;
}
if (item.userList) {
item.children = item.userList;
delete item.userList;
if (item.children.length) {
this.copyTransFun(item.children);
}
}
});
}
copyTransFun(HouChen)
修改后的数据
{
person: '羽神', age: 13, sex: '女', children: [{
id: 1, Z_person: '钢铁侠' }] },
{
person: '少主', age: 14, sex: '女', children: [{
id: 2, Z_person: '蜘蛛侠' }] },
{
person: '刘备', age: 15, sex: '女', children: [{
id: 3, Z_person: '绿巨人' }] },
{
person: '关于', age: 17, sex: '女', children: [{
id: 4, Z_person: '美国队长' }] },
{
person: '老威', age: 15, sex: '男', children: [{
id: 5, Z_person: '冲锋侠' }] },
{
person: '村长', age: 13, sex: '女', children: [{
id: 6, Z_person: '峡谷先锋' }] }
