Shipping with Chrome 66 is an implementation of the new Async Clipboard API. Its asynchronous nature makes it the preferred way – over document.execCommand – to perform copy-paste operations in the browser.
// Write Text to the Clipboard (e.g. copy)
navigator.clipboard.writeText('Text to be copied')
.then(() => {
console.log('Text copied to clipboard');
})
.catch(err => {
// This can happen if the user denies clipboard permissions:
console.error('Could not copy text: ', err);
});
// Read Text from Clipboard (e.g. Paste)
navigator.clipboard.readText()
.then(text => {
console.log('Pasted content: ', text);
})
.catch(err => {
console.error('Failed to read clipboard contents: ', err);
});
