Javascript is an important part of many of the websites that you visit every day.

The steps above show you where to find the setting for Javascript in the default Safari browser so that you can enable it or disable it as needed.

Note that this will only affect Javascript on Web pages that you visit in Safari. If you are using another browser like Chrome or Firefox then you would need to follow the steps for changing the Javascript setting in those browsers instead.

It’s fairly rare that you will need to disable Javascript for most modern websites, so this is probably a setting that you won’t need to use much unless you are a designer or developer that needs to view Web pages with or without Javascript.

You might also need to change the Safari Javascript setting if you are troubleshooting an issue and can’t seem to find a solution to it after doing common troubleshooting tasks like clearing Website data and history.

If you are going through the troubleshooting process then some other things you might want to consider are:

  • Go to Settings > Safari > Clear History and Website Data to remove the browser data that is saved on the device.
  • Restart the iPhone by pressing and holding the Power button and the Volume Down button, then move the Slide to power off slider.
  • Close the tabs that are currently open in the browser.
  • Close Safari by swiping up and to the left from the bottom of the screen, then drag the Safari browser to the top of the screen.
