Question

  clipText => document.querySelector("#Note").innerText += clipText);

But It has this error:

Uncaught TypeError: navigator.clipboard.readText is not a function

help me to solve this bug

Answer 1

I'm guessing you are testing it in Firefox, in that case:

Firefox only supports reading the clipboard in browser extensions, using the "clipboardRead" extension permission.
