Unblocking the context menu: How entering JS directly into the address bar compares to using a bookmark

Exploring the concept of blocking the context menu using JavaScript.

Here's how you can block such a menu:

document.addEventListener('contextmenu', event => event.preventDefault());

I recently came across an article that mentioned this blocking being reversible by typing the following into the address bar:

javascript:void(document.oncontextmenu=null);

I decided to test this in Chrome on Windows. However, pasting it directly didn't work as expected and instead triggered a search query on Google. Instead, creating a bookmark with the code and applying it on the target page did unblock the context menu successfully.

This raises two questions: 1. What sets apart manually inputting the script in the address bar versus using a bookmark? 2. Is there another way to execute this script without a bookmark? Does it vary depending on the browser or other factors?

Answer №1

If you're feeling adventurous, try entering this code into your browser's address bar to search for 'void(alert('foo'))'

javascript:void(alert('foo'))

Alternatively, type it out yourself, press enter, and watch the alert message pop up.

It may not serve any specific purpose, but I found it interesting enough to pass along.
