How do I call an Angular 2 pipe with multiple arguments

Question

Can you explain with an example that How do I call an Angular 2 pipe with multiple arguments?

Answer 1

You can call a pipe with multiple arguments by passing them after the pipe name, separated by colons (:). These arguments are forwarded to the transform method of the pipe as additional parameters.

Syntax:

{{ value | pipeName:arg1:arg2:arg3 }}

Run HTML

Steps:

Define the Pipe:

Ensure the pipe's transform method accepts the additional arguments.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({ name: 'customPipe' })

export class CustomPipe implements PipeTransform {

  transform(value: any, arg1: any, arg2: any, arg3: any): any {

    // Use value, arg1, arg2, and arg3 for transformation

    return `${value} - ${arg1} - ${arg2} - ${arg3}`;

  }

}

Call the Pipe in the Template:

Pass the arguments after the pipe name.

<p>{{ 'Hello' | customPipe:'arg1':'arg2':'arg3' }}</p>

<!-- Output: Hello - arg1 - arg2 - arg3 -->
