I have 1 array, one with a list of all my users with unique IDs. I have an object which contains contains a selected groups information. Part of that information is the owners ID. I'm trying to figure out, how do I get the users's information given the groups owner ID? For example, the student group object has an owner ID of 70, there's a user on my sites who's ID is 70...how do I match them up?

users: 

[  { 

id: 68

name: mike

domain: i:0#.f|admembers|mike.ca

email: mike.ca

isAdmin: False

 }, etc etc ]



selectedGroup:  { 

name: Students

id: 78

description: 

owner: 70

ownerIsUser: True

 }

You'll have to loop through users:

var i = users.length,

    ownerData;



while(i--) {

    if(selectedGroup.owner == users[i].id) {

        ownerData = users[i];

        break;

    }

}

Or you could use Array.filter():

var ownerData = users.filter(function(user) {

    return user.id === selectedGroup.owner;

})[0];
