read clipboard in javascript

To read the contents of the clipboard in JavaScript, you can use the Clipboard API.

First, you need to listen for the "paste" event using the addEventListener method. When the "paste" event is triggered, you can access the contents of the clipboard through the Data Transfer object provided by the ClipboardEvent.

Here's an example code snippet that demonstrates how to read the text contents of the clipboard:

index.tsx
document.addEventListener('paste', function(event) {
  // Get the clipboard data as text
  const clipboardData = event.clipboardData || window.clipboardData;
  const text = clipboardData.getData('text');
  
  // Do something with the text
  console.log('Clipboard contents:', text);
});

In the above code, we listen for the "paste" event on the document. When the event is triggered, we get the clipboard data using the getData method of the Data Transfer object. We specify 'text' as the data format, since we want to read the text contents of the clipboard.

Finally, we log the text contents to the console.
