i have two array, lets say priceArray= [1,5,3,7]
userIdArray=[11, 52, 41, 5]
i need to sort the priceArray, so that the userIdArray will be also sorted. for
Building on Rrowland's answer, you can create the array of objects with a library like lodash:
var prices = [1, 5, 8, 2];
var userIds = [3, 5, 1, 9];
var pairs = _.zipWith(prices, userIds, function(p, u) {
return { price: p, userId: u };
});
This will give you an object like:
[
{ price: 1, userId: 3 },
{ price: 5, userId: 5 },
... etc
]
Then, for sorting, you can simply use a Javascript sort:
pairs.sort(function(p) { return p.price });
If you really need it as an array of userIds, you can get it back, after the sort:
var sortedUserId = pairs.map( function(p) { return p.userId });
// returns [ 3, 9, 5, 8 ];
