JavaScript is normally enabled in Safari on an iPhone 11. If a website says JavaScript is disabled, you can check Safari’s advanced settings and turn it back on.
Enable JavaScript on an iPhone 11
- Open Settings.
- Scroll down and tap Apps, then choose Safari.
- Scroll to the bottom and tap Advanced.
- Turn on JavaScript.
- Return to Safari and reload the webpage.
On older iOS versions, Safari appears directly on the main Settings screen instead of under Settings > Apps. The JavaScript switch is still found in Safari’s Advanced settings.
Should JavaScript be enabled?
For most people, yes. Modern websites use JavaScript for menus, forms, sign-ins, video players, shopping carts, and other interactive features. Turning it off can make many sites partially or completely unusable.
If one particular site still does not work after JavaScript is enabled, the problem may instead be content blockers, cookies, a VPN, a Safari extension, or the site itself. Try reloading the page and testing another website before changing more settings.
You generally do not need to restart the iPhone after changing this option.
