Can not copy empty string (vue.js)

When data-clipboard-text has empty string (‘’), nothing is copied to the clipboard and the previous clipboard value is not removed.

<button id="cp1" data-clipboard-text="something">Copy</button>
<button id="cp2" data-clipboard-text="">Copy</button>

Expected: After click on cp1, clipboard contains “something”. After click on cp2, clipboard contains “” (empty string) OR nothing.

Actual: After click on cp1, clipboard contains “something”. After click on cp2, clipboard contains “something”.

I still disagree that it’s a good idea to replace a user’s clipboard with empty information but that doesn’t really matter. Feel free to save an empty space using Clipboard.js or use execCommand directly to achieve the behavior you’re looking for.

In general, every action should support undo to default state. And after all, empty string is just ordinary string, why the special behavior? clipboard.js is universal tool, not final implementation of specific use case.
