If you have turned the Javascript setting on in the Safari settings menu then you should be able to open the Safari browser, browse to a Web page, and view that page as it was intended to be viewed.

If you had opened a page before you enabled Javascript then you may need to refresh the page. You can do that by opening the tab in Safari, then tapping the arrow in the address bar at the top of the screen.

If the site still isn’t working properly, such as if your account login isn’t being remembered or a shopping cart keeps emptying, then that might be due to an issue with cookies instead. You might need to turn off the Block All Cookies option on the Safari menu to see if that fixes the problem.

The steps above allow you to change the setting for the Safari Web browser on your iPhone. This won’t affect other Web browsers that you may be using on the device, such as Google Chrome, Mozilla Firefox, Microsoft Edge, and others. If a third-party browser has a Javascript setting and you want to change that setting then you will need to do so through the settings for that app.

It’s uncommon to disable Javascript on an iPhone, so most phones will have Javascript enabled. Disabling Javascript in Safari is usually only done as a troubleshooting issue.

Some websites will still work even with Javascript turned off. However, all of the features that are available on that site may not be available until you turn it back on. Most websites provide their visitors with the optimal experience when the Javascript control is enabled in the Advanced menu of your Safari settings.

The Javascript setting on the Apple iPhone can be turned on or turned off as needed. You simply need to return to the Safari Advanced settings menu and enable or disable it as needed.

Another Safari app setting that many people look for involves blocking cookies. You will find this setting in the Privacy & Security section on the Settings > Safari menu. Just below that section, you will find a button to Clear History and Website Data that you may wish to use if you want to delete the history of all of the Web pages that you have visited in Safari. Note that this only clears the Safari history. If you use other browsers you will also need to clear history there, too.
