Sample Input:
[
{
"id": "p1",
"top": 130,
"left": 298,
"Key": "test1",
"Next": "special"
},
{
"id": "p2",
"Key": "special",
"specialkey": [
{"key": "1", "value": "p3"},
{"key": "0", "value": "p4"},
{"key": "2", "value": "p5"}
],
"Next": "",
"RepeatText": "p8",
"RepeatTextNew": "p9",
},
{
"id": "p3",
"user": "aa",
"Key": "test3",
"Text": "hi"
},
{
"id": "p4",
"Key": "special",
"specialkey": [
{"key": "1", "value": "p6"},
{"key": "0", "value": "p7"}
]
},
{
"id": "p5",
"user": "aa",
"Key": "test5",
"Text": "hi"
},
{
"id": "p6",
"user": "aa",
"Key": "test6",

},
{

},
{

"Key": "test8",
"Text": "hi"
},
{
"id": "p9",
"user": "aa",
"Key": "test9",
"Text": "hi"
}
]
Sample Output:
{
"test1": {
"id": "p1",
"top": 130,
"left": 298,
"Key": "test1",
"Next": {
"special": {
"id": "p2",
"Key": "special",
"Next": "",
"RepeatText": {
"p8": {
"id": "p8",
"user": "aa",
"Key": "test8",
"Text": "hi"
}
},
"RepeatTextNew": {
"p9": {
"id": "p9",
"user": "aa",
"Key": "test9",
"Text": "hi"
}
},
"specialkey": [
{
"key": "1",
"value": {
"id": "p3",
"user": "aa",
"Key": "test3",
"Text": "hi"
}
},
{
"key": "0",
"value": {
"id": "p4",
"Key": "special",
"specialkey": [
{
"key": "1",
"value": {
"id": "p6",
"user": "aa",
"Key": "test6",
"Text": "hi"
}
},
{
"key": "0",
"value": {
"id": "p7",
"user": "aa",
"Key": "test7",
"Text": "hi"
}
}
]
}
},
{
"key": "2",
"value": {
"id": "p5",
"user": "aa",
"Key": "test5",
"Text": "hi"
}
}
]
}
}
}
}
When the key is equal to special
it can have a nested structure and for either we just need to match with the next key
With the below code, I am not able to achieve the expected output.
const processObject = ({ Next, ...rest }) => {
const result = { ...rest };
if (formatData.find((y) => y.Key == 'special')) {
const nextObject = formatData.find((y) => y.Key == 'special')
if (nextObject.specialkey) {
for (let i = 0; i < nextObject.specialkey.length; i++) {
let currentObject = formatData.find((y) => y.id === nextObject.specialkey[i].value)
nextObject.specialkey[i].value = currentObject
}
result.Next = {
[nextObject.Key]: processObject(nextObject),
};
}
}
if (Next) {
const nextObject = formatData.find((y) => y.id === Next);
result.Next = {
[nextObject.Key]: processObject(nextObject),
};
}
return result;
};
const response = {
[formatData[0].Key]: processObject(formatData[0]),
};
return response
Is this what you're after?
const input = [ { "id": "p1", "top": 130, "left":298, "Key": "test1", // I've changed this from "special" to "p2" "Next": "p2" // rest of input is the same... },{"id":"p2","Key":"special","specialkey":[{"key":"1","value":"p3"},{"key":"0","value":"p4"},{"key":"2","value":"p5"}],"Next":"","RepeatText": "p8","RepeatTextNew":"p9"},{"id":"p3","user":"aa","Key":"test3","Text":"hi"},{"id":"p4","Key":"special","specialkey":[{"key":"1","value":"p6"},{"key":"0","value":"p7"}]},{"id":"p5","user":"aa","Key":"test5","Text":"hi"},{"id":"p6","user":"aa","Key":"test6","Text":"hi"},{"id":"p7","user":"aa","Key":"test7","Text":"hi"},{"id":"p8","user":"aa","Key":"test8","Text":"hi"},{"id":"p9","user":"aa","Key":"test9","Text": "hi"}]; // Gets an object by its id const getById = id => input.find(x => x.id === id); const processObject = ({ Next, specialkey, RepeatText, RepeatTextNew, ...rest }) => { let processedNext; if (Next) { const nextObject = getById(Next); processedNext = { [nextObject.Key]: processObject(nextObject) }; } return {...rest, // This spread syntax means we don't add the Next or // specialkey property if it isn't present in the input // object...processedNext? { Next: processedNext }: {}, ...RepeatText? { RepeatText: { [RepeatText]: processObject(getById(RepeatText)) } }: {}, ...RepeatTextNew? { RepeatTextNew: { [RepeatTextNew]: processObject(getById(RepeatTextNew)) } }: {}, ...specialkey? { specialkey: specialkey.map(({ key, value }) => ({ key, value: processObject(getById(value)) })) }: {} }; } console.log(processObject(input[0]));
In your code, you seem to be looking up objects by their id
, so that's why I changed the first object input's Next
from "special"
(the Key
of the p2
object) to "p2"
.
