我有以下格式的动态JSON数组,
let main_data = [
{
"client":[
{
"name":"aaaa",
"count":"1",
"filter":{
"type":{
"name":"test3"
}
}
},
{
"name":"bbbb",
"count":"9",
"filter":{
"type":{
"name":"test2"
}
}
}
]
},
{
"compute":[
{
"name":"cccc",
"count":"6",
"filter":{
"type":{
"name":"test"
}
}
}
]
}
]
此处的键“名称”是唯一的。更新表单时,我将得到如下的json数组,
let new_data = [
{
"client":[
{
"name":"bbbb",
"count":"1234",
"type":{
"name":"updated_name"
}
}
}
]
}
]
我需要检查“main_data”中json数组中的“名称”,并删除现有的名称,并使用新的“updated_data”更新到“main_data”中。 (请不要使用Jquery)
预期输出
let main_data = [
{
"client":[
{
"name":"aaaa",
"count":"1",
"filter":{
"type":{
"name":"test3"
}
}
},
{
"name":"bbbb",
"count":"123",
"filter":{
"type":{
"name":"updated_name"
}
}
}
]
},
{
"compute":[
{
"name":"cccc",
"count":"6",
"filter":{
"type":{
"name":"test"
}
}
}
]
}
]
有什么办法可以做到这一点。任何帮助将非常感激。提前致谢。
最佳答案
试试这个
let main_data = [{
client: [{
name: "aaaa",
count: "1",
filter: {
type: {
name: "test3"
}
}
},
{
name: "bbbb",
count: "9",
filter: {
type: {
name: "test2"
}
}
}
]
},
{
compute: [{
name: "cccc",
count: "6",
filter: {
type: {
name: "test"
}
}
}]
}
];
let new_data = [{
client: [{
name: "bbbb",
count: "1234",
filter: {
type: {
name: "updated_name"
}
}
}]
}];
const res = main_data.map((item, index) => {
if (item.client) {
const clients = item.client.map(client => {
if (client.name === new_data[0].client[0].name) {
client = new_data[0].client[0];
}
return client;
});
return {
client: clients
};
}
return item;
});
console.log(res);
关于javascript - 有没有办法用基于 key 的新对象替换JSON数组中的现有对象,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/60967515/
