I'm new to Vue and Javascript and for my work I need to find the specific room certain user connected to. I'm still learning so i'm not very good with ES6 or javascript functions.
I need to search userId in rooms and return the name of the key ('pre', 'mid', 'post') if the id is found, if not then return null
const userId = "321b66bb-b44f-4859-994a-a339e604df62";
const rooms = {
"pre": [
{
"id": "321b66bb-b44f-4859-994a-a339e604df62",
"name": "George",
"age": "27",
"color": "#0B8043",
"callIndex": 960433
},
{
"id": "1111111-11111-1111-1111-111111111111",
"name": "John",
"age": "30",
"color": "#0B8043",
"callIndex": 4444444
},
],
"mid": [
{
"id": "1111111-11111-1111-1111-111111111112",
"name": "John2",
"age": "30",
"color": "#0B8043",
"callIndex": 4444444
},
],
"post": []
};
You can iterate through each key and then compare the id with passed userId and return then key name.
const userId = "321b66bb-b44f-4859-994a-a339e604df62",
rooms = { "pre": [ { "id": "321b66bb-b44f-4859-994a-a339e604df62", "name": "George", "age": "27", "color": "#0B8043", "callIndex": 960433 }, { "id": "1111111-11111-1111-1111-111111111111", "name": "John", "age": "30", "color": "#0B8043", "callIndex": 4444444 }, ], "mid": [ { "id": "1111111-11111-1111-1111-111111111112", "name": "John2", "age": "30", "color": "#0B8043", "callIndex": 4444444 }, ], "post": [] },
result = Object.keys(rooms).find(k => rooms[k].some(({id}) => id === userId)) || null;
console.log(result);Easy task
const userId = "321b66bb-b44f-4859-994a-a339e604df62";
const rooms = {
"pre": [{
"id": "321b66bb-b44f-4859-994a-a339e604df62",
"name": "George",
"age": "27",
"color": "#0B8043",
"callIndex": 960433
},
{
"id": "1111111-11111-1111-1111-111111111111",
"name": "John",
"age": "30",
"color": "#0B8043",
"callIndex": 4444444
},
],
"mid": [{
"id": "1111111-11111-1111-1111-111111111112",
"name": "John2",
"age": "30",
"color": "#0B8043",
"callIndex": 4444444
}, ],
"post": []
};
function search(id) {
for (let key in rooms) {
// key is pre, mid or post
for (let item of rooms[key]) {
// item is an object containing id
if (item.id === id) return key
}
}
return null
}
console.log(search(userId))
