	text.select();
	try {
		document.execCommand('copy');

copyText('JS is love');

推荐答案

1. .select()函数调用不属于字符串，而是HTMLInputElement，例如TextArea
2. document.execCommand('copy')只能作为用户操作的结果运行.换句话说，它必须属于诸如'click'
之类的EventListener中

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'
