Access the $event object from an Angular template selector

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<input type="file" #myFile multiple />
<button (click)="onDelete(myFile.event)">DeleteFiles</button>

My code snippet is experiencing an issue where myFile.event is returning undefined. I am trying to figure out how to get the myFile $event through a button click, as I specifically need to delete only one file from the user's selection.

Answer №1

If you want to delete files, consider using this code snippet:

<button (click)="onDelete($event)">Delete Files</button>

Answer №2

It seems like the use of $event might not be necessary in your case. Consider using this approach instead:

<input type="file" #myFile multiple>
<button (click)="onDelete(myFile.files)">DeleteFiles</button>

Alternatively, you could try:

<input type="file" #myFile multiple>
<button (click)="onDelete(myFile.value)">DeleteFiles</button>
