Angular – On Paste Event Get Content

You can get the pasted content from the paste event and the updated content of the textarea by handling the input event:

<textarea #myText (paste)="onPaste($event)" (input)="onInput(myText.value)"></textarea>

with this code:

onPaste(event: ClipboardEvent) {
  let clipboardData = event.clipboardData || window.clipboardData;
  let pastedText = clipboardData.getData('text');
  ...
}

onInput(content: string) {
  ...
}
