Angular - On Paste Event Get Content

This is from an example with angular2 typescript that works for my project. Hope it helps someone. Logic is same for other cases as-well.

1. angular-clipboard-event.html

<textarea placeholder="Type a message" (paste)="onPaste($event)"></textarea>
<!-- Place to render the image -->
<img #imgRenderer />

2. angular-clipboard-event.ts

// Reference to the dom element
@ViewChild('imgRenderer') imgRenderer: ElementRef;

onPaste(event: any) {
    const items = (event.clipboardData || event.originalEvent.clipboardData).items;
    let blob = null;

    for (const item of items) {
      if (item.type.indexOf('image') === 0) {
        blob = item.getAsFile();
      }
    }

    // load image if there is a pasted image
    if (blob !== null) {
      const reader = new FileReader();
      reader.onload = (evt: any) => {
        console.log(evt.target.result); // data url!
        this.imgRenderer.nativeElement.src = evt.target.result;
      };
      reader.readAsDataURL(blob);
    }
  }

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) {
  ...
}
