How to find name using id. means iterate object. create a function const searchName =()=>{}
suppose if pass 3 in function so I'd want to show .... what the name of user like this
const data = [{
"service": [
"BUSINESS",
"LEGAL",
"FINANCE",
"ADVERTISEMENT"
],
"service1": [
{ "id": 1, "name": "a" },
{ "id": 2, "name": "b" },
{ "id": 3, "name": "c" },
{ "id": 4, "name": "d" },
],
"service2": [
{ "id": 5, "name": "e" },
{ "id": 6, "name": "f" },
{ "id": 7, "name": "g" },
{ "id": 8, "name": "h" },
],
"service3": [
{ "id": 9, "name": "i" },
{ "id": 10, "name": "j" },
{ "id": 11, "name": "k" },
{ "id": 12, "name": "l" },
],
"service4": [
{ "id": 13, "name": "m" },
{ "id": 14, "name": "n" },
{ "id": 15, "name": "o" },
{ "id": 16, "name": "p" },
],
}
]
suppose user pass 3 so I want to return { "id": 3, "name": "c" } like this.
I'm trying to iterate this and find the name of the user by id but I didn't understand this iteration so I need your help.
check this code.... Enter any id number
const data = [{
"service": [
"BUSINESS",
"LEGAL",
"FINANCE",
"ADVERTISEMENT"
],
"service1": [
{ "id": 1, "name": "a" },
{ "id": 2, "name": "b" },
{ "id": 3, "name": "c" },
{ "id": 4, "name": "d" },
],
"service2": [
{ "id": 5, "name": "e" },
{ "id": 6, "name": "f" },
{ "id": 7, "name": "g" },
{ "id": 8, "name": "h" },
],
"service3": [
{ "id": 9, "name": "i" },
{ "id": 10, "name": "j" },
{ "id": 11, "name": "k" },
{ "id": 12, "name": "l" },
],
"service4": [
{ "id": 13, "name": "m" },
{ "id": 14, "name": "n" },
{ "id": 15, "name": "o" },
{ "id": 16, "name": "p" },
],
}]
var itemobj = ''
const searchName =(val)=>{
console.log('searchname')
data.map((item)=>{
let obj = Object.keys(item)
obj.map((data)=>{
let inrdata = item[data]
inrdata.map((initem)=>{
let lastdata = initem.id===val?itemobj=initem:null
})
})
})
}
searchName(3)
console.log(itemobj)function searchName(id) {
let result = null;
for (const [key, value] of Object.entries(data)) {
if (key === "service") continue
result = value.filter(obj => {
return obj.id === id
})
if (result) break
}
return result ? result[0] : null
}
I iterate through keys, I just skip "service" one since it's not revelant. Then, I filter the "serviceN" array, it will return an array of object (only one if found, empty array if not found).
If it's found, we stop iterating.
Then we return either the first (and logically only element) or null if not found
