1.复制文字

onCopy = (url: string) => {
    let input = document.createElement('input');
    input.value = url;
    document.body.appendChild(input);
    input.select();
    if (document.execCommand('Copy')) {
        AntMessage.success('复制成功');
    } else {
        AntMessage.warning('复制失败');
    }
    document.body.removeChild(input);
};

2.复制文字，并里面的根绝逗号 换行

onCopy = () => {
	const url = "1,2,3,4,5";
    let input = document.createElement('textarea');
    let urlArray = url.split(',');
    const urls: string = urlArray
        .map((u: string) => {
            return `${u}\r\n`;
        })
        .join('');
    input.value = urls;
    document.body.appendChild(input);
    input.select();
    if (document.execCommand('Copy')) {
        AntMessage.success('复制成功');
    } else {
        AntMessage.warning('复制失败');
    }
    document.body.removeChild(input);
    };
