Return value from Object match
- by Hito_kun
I'm, by no means, JS fluent, so forgive me if im asking for some really basic stuff, but I've not being able to find a proper answer to my question.
Im writting my first Node.js (plus Extra Framework and Socket.io) app and Im having some fun setting up the server side of a FB-like messenger (surprise!!!).
So, let's say I have this data structure to store online users(This is a JSON Array, but I'm not sure it is the best way to do it or should I go with Javascript Objects):
[
{
"site": 45,
"users": [
{
"idUser": 5,
"idSocket": "qwe87r7w8qwe",
"name": "Carlos Ray Norris"
},
{
"idUser": 6,
"idSocket": "v8d9d0fgfs7d",
"name": "John Connor"
}
]
},
{
"site": 48,
"users": [
{
"idUser": 22,
"idSocket": "qwe87r7w8qwe",
"name": "David Bowie"
},
{
"idUser": 23,
"idSocket": "v8d9d0fgfs7d",
"name": "Barack H. Obama"
}
]
}
]
What I want to do is to search in the array for x value given y. In this case, retrieving the idSocket knowing the idUser WITHOUT having to run through the array values.
So I have basically 2 questions: first, what would be the proper way to store users online? and secondly, how to find values matching with the values I already know (find the idSocket that has a given idUser).
I would like a pure JS approach(or using some of the tools given by Node, Socket.io or Express), but if that's not possible then I can look for some JQuery.
