Not working inside cross-domain iframe about clipboard-copy HOT 4 CLOSED

I came across the same issue, digged into it and it turned out that it was actually the browser which blocked
a write operation to the clipboard.

I saw this error message on the console when I tried to copy a text:
DOMException: The Clipboard API has been blocked because of a Feature Policy applied to the current document. See https://goo.gl/EuHzyv for more details.

In order to avoid this issue, you need to pass the value clipboard-write to the allow attribute in your iframe like so:

<iframe ... allow="clipboard-write"></iframe>

from clipboard-copy.

@hamaron I can confirm you are right, thanks!

Although this attribute value is not fully supported yet, I tested and it seems like it's not working in any mobile browser (iOS or Android).

@petedol87 Hi, I'm trying to use the library within the webview both on iOS and Android. When I tested, I noticed that copying to clipboard doesn't work on the Android emulator while it works on the iOS simulator. I was wondering if there's anything I'm missing, or is that somewhat related to this OP?

I'm closing this issue since there's no bug to fix here, but feel free to continue discussion! ✨
