how to get array in difrrent order code example
Example 1: sort arrays according to first array js
itemsArray.sort(function(a, b){
return sortingArr.indexOf(a) - sortingArr.indexOf(b);
});
Example 2: sort array based on another array js
function mapOrder (array, order, key) {
array.sort( function (a, b) {
var A = a[key], B = b[key];
if (order.indexOf(A) > order.indexOf(B)) {
return 1;
} else {
return -1;
}
});
return array;
};
var item_array, item_order, ordered_array;
item_array = [
{ id: 2, label: 'Two' }
, { id: 3, label: 'Three' }
, { id: 5, label: 'Five' }
, { id: 4, label: 'Four' }
, { id: 1, label: 'One'}
];
item_order = [1,2,3,4,5];
ordered_array = mapOrder(item_array, item_order, 'id');
console.log('Ordered:', JSON.stringify(ordered_array));
