I want to retrieve a boolean value that reflects the current status of clipboard permissions.
To determine if you have the necessary permissions to access the clipboard, utilize the Permissions API:
const permissionStatus = await navigator.permissions.query({ name: 'clipboard-read' });
// alternatively use 'clipboard-write' for write permission
// example output: {state: 'granted'}
There are three possible states for clipboard read permission: granted, denied, or prompt indicating "neither denied nor granted".
Here is an example of how your code could be structured:
const queryOptions = { name: 'clipboard-read', allowWithoutGesture: false };
const status = await navigator.permissions.query(queryOptions);
// This will be either 'granted', 'denied', or 'prompt':
console.log(status.state);
// Keep track of changes in the permission state
status.onchange = () => {
console.log(status.state);
};
Code reference: https://web.dev/async-clipboard/
Based on the above code snippet, you can create a function that returns true or false like so:
// Pass the permissionStatus.state to this function
const checkClipboardPermission = (state) => {
if(state == "granted"){
return true;
}
else if(state == "denied"){
return false;
}
else {
return false;
}
}
