Ciri-ciri Utama

One-Click Toggle

Disable JavaScript for the current tab with a single click. The page reloads automatically to show the no-JS version. Click again to re-enable. The toggle state is clearly shown (JS ON / JS OFF).

Per-Tab Isolation

Only affects the current tab. Other tabs, other windows, and other sites continue running JavaScript normally. You can have JS disabled on one tab and enabled on another simultaneously.

Automatic Page Reload

The page reloads automatically after toggling to ensure the change takes effect cleanly. No manual refresh needed — the no-JS or with-JS version loads immediately.

SSR Verification

See exactly what content is available without JavaScript — the same view that search engine crawlers (Googlebot in its initial HTML-only pass) see. Verify that critical content is server-rendered, not client-only.

Progressive Enhancement Testing

Test whether your site's core functionality works without JavaScript. Forms should still submit, links should still navigate, and content should still be readable when JS is disabled.

Behavior Impact Summary

When JS is disabled, a summary shows what's affected: dynamic content won't load, SPAs won't navigate, forms may not validate client-side, and interactive widgets will be static. Helps you understand what to expect.

Kes Penggunaan Biasa

SEO Crawl Verification

Search engines may not execute JavaScript on every crawl. Disable JS to see what Googlebot's initial HTML pass sees. If your content, meta tags, and links are missing without JS, they might not be indexed.

Progressive Enhancement Testing

Verify that your site's core experience works without JavaScript. Users on slow connections, with JS blockers, or using assistive technologies may encounter your no-JS version.

Debugging JavaScript Errors

A page is broken — is it a JavaScript error or a CSS/HTML issue? Disable JS. If the problem persists, it's not JS-related. If it disappears, you know the bug is in your JavaScript code.

Testing noscript Fallbacks

Verify that your noscript tags and no-JS fallback content display correctly when JavaScript is unavailable. Ensure users see a meaningful message rather than a blank page.

Performance Baseline Testing

See how fast the page loads without any JavaScript execution. This shows the baseline HTML/CSS rendering performance and helps identify how much JavaScript is slowing down the initial load.

Cara Guna

Click to Disable

Click the toggle to disable JavaScript. The page reloads to show the no-JS version. The toggle shows "JS OFF" in red.

3

Test the No-JS Experience

Browse the page without JavaScript. Check if content is visible, navigation works, and forms function. Note what breaks or degrades.

4
