TypeError: Failed to construct 'ClipboardItem': Failed to convert value to 'Blob'
assuming your message is string type, here is a demo code
your code would be
navigator.permissions.query({ name: 'clipboard-write' }).then(result => { if (result.state === 'granted') { const type = 'text/plain'; const blob = new Blob([message], { type }); let data = [new ClipboardItem({ [type]: blob })]; navigator.clipboard.write(data).then(function() { $.growl.notice({ message: ResourceService.getKey("CopyToClipboardSuccess"), location: "tc", title: "" }); }, function() { $.growl.error({ message: ResourceService.getKey("CopyToClipboardError"), location: "tc", title: "" }); }); }});but Clipboard API and events are still working draft, I recommend using an alternatives like clipboard.js
