Arranging Elements in Reverse Order Using ngx-order-pipe

I have successfully sorted an Array in ascending order, but now I am struggling to figure out how to implement sorting in descending order using ngx-order-pipe.

  1. $ npm install ngx-order-pipe --save
  2. TS

    dummyData: any[] = [
        { name: 'G' },
        { name: 'B' },
        { name: 'Z' },
        { name: 'A' },
        { name: 'H' }
    ];
    
  3. HTML

    <div *ngFor="let item of (dummyData | orderBy:'name') ">
        <p>{{item.name}}<p>
    </div>
    

Does anyone have suggestions on how to achieve sorting in descending order?

Answer №1

There is a single argument known as reverse

<div *ngFor="let item of (dummyData | orderBy:'name' : true) ">
    <p>{{item.name}}<p>
</div>

Found in an HTML template

{{ collection | orderBy: expression : reverse : caseInsensitive : comparator }}

Answer №2

Here is a simple HTML and TypeScript code snippet:

<div *ngFor="let item of (dummyData | orderBy:'name':reverse)">
  <p>{{item.name}}</p>
</div>

In the TypeScript file:

reverse: boolean = false;

sort() { // Call this function on click event to trigger sorting
  this.reverse = !this.reverse;
}

Use this code to toggle between Ascending and Descending order.
