Arrange records in ascending order by phone number when multiple are returned on the same date

Question

Arrange records in ascending order by phone number when multiple are returned on the same date

Currently, I am working on an Angular application that is designed to keep track of tuxedo rentals. The main feature of the app is a table that displays information from an array stored in the controller.

The initial task I completed was listing the items in the table by return date in ascending order. This was achieved by utilizing the lodash orderBy filter.

However, I am facing a challenge with the second task: if multiple records have the same return date, they should be sorted by phone number in ascending order. While sorting the phone numbers individually is not complex, my difficulty lies in figuring out how to sort only those entries with the same date without altering the order of the return dates for the entire collection.

Answer №1

If you want to simplify the sorting process, Angular offers a convenient sort directive that allows you to specify multiple columns for sorting in a specific order.

To achieve this, use the syntax

{{ array | orderBy : expression : reverse }}

. You can define an array of columns to sort by, such as ['name', 'age'], for the expression argument. Additionally, you can set true or false (or leave it blank) for the reverse argument to toggle between ascending and descending order.

An example implementation without a reverse argument would be:

<tr class="dataRow" ng-repeat="item in vm.items track by $index | orderBy:['name','age']">
