All websites listed in the Block section will automatically be blocked from running the JavaScript code.

Allow the JavaScript Execution

If you have already blocked the JavaScript and the website is not loading correctly, then problem may be with JS settings. In that case, you should allow the execution. Here are the steps to follow:

1. Launch Google Chrome on your computer.
2. Click on the More  menu list and select Settings menu.
3. Scroll down to the Privacy and Security section, and select the Site settings from the menu.
4. Choose the JavaScript option within Site settings.
5. Click on the toggle button to Allow the JavaScript.
   

It will allow all the websites to run the JavaScript code on the browser and execute the function within the code block. However, if you want to allow JavaScript execution on a few websites, you can find all the URLs in the Allow section.

The website in the allow section will run the JavaScript code irrespective of the main switch.

Bottom Line

We can easily block the JavaScript on selected sites or allow the execution in the Chrome browser.

If you block the JavaScript execution, the website might not run as expected. Perhaps, you should block only the untrusted sites that you are willing to visit.

Similarly, you can allow or block JavaScript in Chrome browser on Android. You allow selected sites to enable JavaScript or block them by adding them to the Block bucket.
