Answer №1

Have you considered implementing a unique filter? By utilizing a custom filter, you have the ability to input your desired formatting string. The filter can then interpret and apply the specified formatting accordingly.

Do you think this approach could be effective for your needs?

To solve the problem, you must develop pipelines.

Example(Replacing ? with N):

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

@Pipe({name: 'replaceQuestionMark'})
export class ReplaceQuestionMarkPipe implements PipeTransform {
  transform(value: string): string {
    // Add your specific logic here
    let updatedValue = value.replace(/\?/g, 'N');
    return `${updatedValue}`;
  }
}

Next, implement it in your HTML code

<p>varName | replaceQuestionMark </p>

This will alter your result accordingly.
