Disable Right-Click Context Menu in JavaScript

When a user on your website or app right-clicks, the contextmenu event is triggered.

We can listen for this event by attaching an event listener to the window interface, but I'd suggest first adding the below one-liner to ensure compatibility with some older browsers:

typeof window.addEventListener === `undefined` && (window.addEventListener = (e, cb) => window.attachEvent(`on${e}`, cb));
Enter fullscreen mode Exit fullscreen mode

Anyway, here is the actual snippet that will listen for the contextmenu event, intercept it, and prevent the default behavior:

window.addEventListener(`contextmenu`, (e) => {
Enter fullscreen mode Exit fullscreen mode

Here is a one-liner variant that is equivalent to the above snippet:

window.addEventListener(`contextmenu`, (e) => e.preventDefault());
Enter fullscreen mode Exit fullscreen mode


While exploring how you can create custom context menus is a bit beyond the scope of this article, I hope you found this snippet useful.

Remember to only disable context menus when absolutely necessary!
