copy command using JS

问题

Please help me solve this code. I've been fixing this for a month. Thank you for helping!

function copyText(text) {
	text.select();
	try {
		document.execCommand('copy');
	} catch (err) {
		console.log('Unable to copy' + err);
	}
}

copyText('JS is love');

1. The .select() function call doesn't belong to strings but instead HTMLInputElement such as TextArea
2. document.execCommand('copy') can only run as a result of an user action. In other words, it must belong inside an EventListener such as 'click'
