Hacker News: collapse all comments
Collapses every top-level comment thread with one click so you can expand only the ones you want.
Code to copy
// Collapse every top-level comment thread at once
(function () {
const togglers = document.querySelectorAll('.comtr .togg');
togglers.forEach(function (t) {
const row = t.closest('.comtr');
const ind = row && row.querySelector('td.ind');
const indent = ind ? parseInt(ind.getAttribute('indent') || '0', 10) : -1;
if (indent === 0 && t.classList.contains('clicky') && t.textContent.indexOf('[') !== -1) {
if (t.innerText.trim() === '[–]' || t.textContent.indexOf('–') !== -1) {
t.click();
}
}
});
