How to Enable or Block JavaScript on Safari iPhone/iPad

Learn how to allow or block the JavaScript execution on the Apple Safari browser for the iPhone or iPad. JavaScript is used to make the website interactive.

All modern websites need JavaScript execution to run the site without any issues. The Apple Safari browser on iPhone and iPad does offer a feature where you can enable or disable JavaScript execution for all the pages. JavaScript is a basic necessity for all sites. But, it can be misused to inject scripts for hacking and data theft.

Configure JavaScript Execution on Safari browser

All the significant websites built these days somehow rely on JavaScript. JavaScript adds an interactive element that is not available in older web technology. Gone are those days when websites were just white or colorful pages with some text and images.

Though JavaScript on iPhone can be used in many valuable ways, many people also misuse this to hijack our browsers. For example, injecting the Marquis search spam in the Safari Mac.

Hence, if you do not need JavaScript for the website, you can block JavaScript for all the websites. This will automatically safeguard you from phishing sites.

Block JavaScript Execution

We can easily block the JavaScript iPhone execution on the Safari browser on iOS and iPadOS devices using a single toggle button.

Here are the steps to block JavaScript execution:

  1. Open the Settings app on the iPhone or iPad.
  2. Scroll down and select the Safari menu from Settings.
  3. From Safari Settings, scroll to the bottom and tap the Advanced menu.
  4. Toggle the JavaScript button to Turn it OFF and disable execution.

This will completely block the JavaScript from running on Safari. If you block the JavaScript on your iPhone, a few websites might not work as intended.

Enable JavaScript

We can enable JavaScript on iPhone and iPadOS devices. All we need to do is toggle the button allowing JavaScript execution on websites. Here are the steps to enable it:

  1. Open the Settings app on the iPhone or iPad.
  2. Scroll down and choose Safari from Settings.
  3. From Safari Settings, scroll to the bottom and tap the Advanced menu.
  4. Toggle the JavaScript button to Turn it ON and enable execution.

This will allow the JavaScript within the website to execute and run on the Safari browser without any issues. This is the recommended setting in most cases.

Bottom Line

By default, the Safari browser is set to allow JavaScript execution for all websites. However, we can completely control whether to allow or disable the Javascript within the Safari browser on the iPhone or iPad.

In most cases, you can keep the Javascript blocked; however, if any website misbehaves, you can quickly toggle the button to enable the Javascript on websites.

I do allow Javascript as I like to keep the interactive website experience. However, when I feel a website is unsafe, I avoid visiting it to protect my privacy and security. In rare cases, I just disabled the JavaScript execution feature and visited the site.

Similarly, you can configure JavaScript on the Safari Mac computer. Like Safari on iOS, there is no site exception within the Safari browser.
