J'ai un JSON comme ci-dessous. J'ai besoin de trouver la valeur de name, dans ce cas, ce sera "Mark". Je ne sais pas à quelle profondeur l'objet se trouve dans la structure JSON ou combien d'entre eux dans le JSON. Il pourrait y en avoir plusieurs à différents niveaux. Je sais que je peux simplement parcourir chaque objet de valeur pour le rechercher. Existe-t-il un moyen plus simple?
{
"person": {
"value": [
{
"type": "RANGE",
"value": {
"to": "2019-11-05T05:59:59.999Z",
"from": "1900-01-01T06:00:00.000Z"
},
"field": "published",
"include": true
},
{
"type": "AND",
"value": [
{
"type": "OR",
"value": [
{
"type": "AND",
"value": [
{
"type": "OR",
"include": true,
"value": [
{
"type": "MATCH",
"value": "Mark",
"field": "name",
"include": true
}
]
}
]
}
]
},
{
"type": "MATCH",
"value": "37",
"field": "age",
"include": true
}
],
"include": true
}
]
}
}

C'est une manière récursive simple de trouver "Mark":
function runThroughObject(object) {
for (const key in object) {
const value = object[key]
if (typeof value === 'object' && value !== null) {
runThroughObject(value)
}
else if (value === 'name') {
console.log(object.value)
}
}
}
Voici l'extrait de travail complet:
const data = {
"person": {
"value": [
{
"type": "RANGE",
"value": {
"to": "2019-11-05T05:59:59.999Z",
"from": "1900-01-01T06:00:00.000Z"
},
"field": "published",
"include": true
},
{
"type": "AND",
"value": [
{
"type": "OR",
"value": [{
"type": "AND",
"value": [{
"type": "OR",
"include": true,
"value": [{
"type": "MATCH",
"value": "Mark",
"field": "name",
"include": true
}]
}]
}]
},
{
"type": "MATCH",
"value": "37",
"field": "age",
"include": true
}
],
"include": true
}
]
}
}
function runThroughObject(object) {
for (const key in object) {
const value = object[key]
if (typeof value === 'object' && value !== null) {
runThroughObject(value)
}
else if (value === 'name') {
console.log(object.value)
}
}
}
runThroughObject(data)
