私は次のようなjson配列を持っています:
{
"id": 1,
"children": [
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
},
{
"id": 2,
"children": {
"id": 3,
"children": {
"id": 4,
"children": ""
}
}
}]
}
「子」が空の要素を削除する機能が欲しいのですが。どうすればいいですか?私は答えを求めているのではなく、提案だけを求めています
