Telegram: copy-message button
Adds a small "Copy" button to each message that copies its text to the clipboard with one click.
Code to copy
// Add a small "Copy" button to each message bubble
function addCopyButtons() {
const msgs = document.querySelectorAll('.bubbles .bubble .message, .Message .text-content');
msgs.forEach(function (m) {
if (m.dataset.jzCopy) { return; }
m.dataset.jzCopy = '1';
const b = document.createElement('button');
b.textContent = 'Copy';
b.style.cssText = 'margin-left:6px;font-size:11px;padding:1px 6px;cursor:pointer;'
+ 'border:1px solid currentColor;border-radius:6px;background:transparent;color:inherit';
b.addEventListener('click', function (e) {
e.stopPropagation();
navigator.clipboard.writeText(m.textContent || '');
});
m.appendChild(b);
});
}
addCopyButtons();
const obs = new MutationObserver(addCopyButtons);
obs.observe(document.documentElement, { childList: true, subtree: true });How to use this example
- Copy the code with the button above.
- Install JustZix (2 minutes) and open the extension on the target page.
- Add a new rule matching that page.
- Paste the code into the rule's JavaScript panel and save — it runs on every page visit.
