JS The clipboardData in ClipboardEvent is perpetually void

I am trying to retrieve files using CTRL+V from the ClipboardEvent in Angular6, but I am encountering an issue where the clipboardData is always empty regardless of whether I test images or text. This problem persists even when tested on the latest releases of Chrome and Firefox.

As shown in the screenshot provided, the files/items attribute remains empty despite my efforts. Below is a snippet of my current code:


  ngOnInit() {
    document.addEventListener('paste', this.pasteEvent);
  }

  private pasteEvent(e): void {
    console.log(e);
  }

Answer №1

Obtaining data from events may pose challenges due to security restrictions and varying levels of browser support.

In order to retrieve data from your event, you will need to utilize the getData(format) method on clipboardData by specifying the desired MIME type (such as 'Text' for text).

private pasteEvent(e): void {
  console.log(e.clipboardData.getData("text/plain");
}

It is uncertain whether it is possible to obtain files in this manner.

Furthermore, the Clipboard API is now supported in current versions of Chrome:

private async pasteEvent(e)  {
  const text = await navigator.clipboard.readText();
  console.log(text);
}

However, please note that the generic read() method is not currently supported.
