Stack Overflow: focus on a single tag feed
On question lists hides every entry without the chosen tag (javascript by default), leaving a focused feed.
Code to copy
/* On question lists, keep only questions tagged "javascript" */
(function () {
var TAG = 'javascript';
function filter() {
document.querySelectorAll('#questions .s-post-summary, .question-summary').forEach(function (q) {
var tags = Array.prototype.map.call(
q.querySelectorAll('.post-tag'),
function (t) { return t.textContent.trim().toLowerCase(); }
);
q.style.display = tags.indexOf(TAG) === -1 ? 'none' : '';
});
}
filter();
new MutationObserver(filter).observe(document.body, { 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.
