javascript - 将整个 html 表复制到剪贴板 javascript

Question

我已经编写了 javascript 来选择表格，但我现在想在单击按钮后自动复制它。请帮助我。我的 javascript 是这样的。

function selectElementContents(el) {
            var body = document.body, range, sel;
            if (document.createRange && window.getSelection) {
                range = document.createRange();
                sel = window.getSelection();
                sel.removeAllRanges();
                try {
                    range.selectNodeContents(el);
                    sel.addRange(range);
                    document.execCommand('Copy');
                } catch (e) {
                    range.selectNode(el);
                    sel.addRange(range);
                    document.execCommand('Copy');
                }
            } else if (body.createTextRange) {
                range = body.createTextRange();
                range.moveToElementText(el);
                range.select();
                range.execCommand('Copy');

            }
        }

function selectElementContents(el) {
var body = document.body, range, sel;
if (document.createRange && window.getSelection) {
    range = document.createRange();
    sel = window.getSelection();
    sel.removeAllRanges();
    try {
        range.selectNodeContents(el);
        sel.addRange(range);
    } catch (e) {
        range.selectNode(el);
        sel.addRange(range);
    }
} else if (body.createTextRange) {
    range = body.createTextRange();
    range.moveToElementText(el);
    range.select();

document.execCommand("Copy");}
