Answer №1

Kindly offer a minimal reproducible example, I will not be able to rewrite your code... However, the issue lies here

<ul> 
  <li *ngFor="let post of objectArray; let i= index;">{{post. postTitle}}</li> 
  <button (click) ='onDelete(i)'></button> <!-- should be inside li -->
</ul>

resolution

Just place the button inside the li tag

<ul> 
  <li *ngFor="let post of objectArray; let i= index;">
    {{post. postTitle}}
    <button (click) ='onDelete(i)'></button>
  </li> 
</ul>

Answer №2

Make sure to set the index as i parameter according to the specified guidelines

Additionally, relocate the button within the li element.

*ngFor="let post of objectArray; index as i"
