javascript - How to implement the green part below?

Question

Click on the part in the red box to copy the code below. How is this implemented? Is there a corresponding js plug-in?

Answer 1

I have used clipboard.js, the size is only 3K, and the support is not bad

The official documentation explains it very clearly, so I won’t elaborate further.

Answer 2

Click to copy, which actually executes the event when you click and adds the relevant content to the computer's clipboard. It uses this interface. The MDN documentation is here: https://developer.mozilla.org... document.execCommand
