var objs = [
{ Product: 'Lazslo', Status: Approved },
{ Product: 'Pig', Status: Rejected },
{ Product: 'Pirate',Status: Pending }
];
How can I sort them by the Status in JavaScript?
I know about sort(a,b), but that only seems to work on asc or desc ?
My output want like this
[{ Product: 'Pirate',Status: Pending }
{ Product: 'Lazslo', Status: Approved },
{ Product: 'Pig', Status: Rejected }];
You can define priority for every status using an object and sort the array using Array#sort:
const statusScores = { 'Pending': 3, 'Rejected': 2, 'Approved': 1 };
const arr = [ { Product: 'Lazslo', Status: 'Approved' }, { Product: 'Pig', Status: 'Rejected' }, { Product: 'Pirate', Status: 'Pending' } ];
const res = arr.sort(({ Status: a }, { Status: b }) => statusScores[b] - statusScores[a]);
console.log(res);var objs = [
{ Product: 'Lazslo', Status: "Approved" },
{ Product: 'Pig', Status: "Rejected" },
{ Product: 'Pirate', Status: "Pending" }
];
var priority = ["Pending", "Approved", "Rejected"];
objs.sort( ( a, b ) => priority.indexOf( a.Status ) - priority.indexOf( b.Status ) );
console.log(objs);Could be refactored to be reusable as such:
var objs = [
{ Product: 'Lazslo', Status: "Approved" },
{ Product: 'Pig', Status: "Rejected" },
{ Product: 'Pirate', Status: "Pending" }
];
var statusPriority = ["Pending", "Approved", "Rejected"];
const sortBy = (arr, priorityArr, propertyName) =>
arr.sort( ( a, b ) => priorityArr.indexOf( a[propertyName] ) - priorityArr.indexOf( b[propertyName] ) );
console.log(sortBy(objs, statusPriority, "Status"));
