Methods: Disable Right Click and F12 Key Using JavaScript

Disabling right click and the F12 key is a common technique used to protect website content. Here’s how to disable both using JavaScript:

Disabling Right Click

Users of web browsers frequently use the right-click context menu, which offers functions like copy, paste, and save picture as. By turning off this function, visitors won’t be able to download or copy any of the content from your website.

To disable the right-click context menu, we need to add an event listener to the contextmenu event and call the preventDefault() method on the event object. Here’s an example code that demonstrates how to disable the right-click context menu on a webpage:

document.addEventListener('contextmenu', function(event) {

In the above code, we are adding an event listener to the contextmenu event, which is triggered when the user right-clicks on the webpage.

Inside the event listener, we are calling the preventDefault() method on the event object, which prevents the default action of opening the right-click context menu.

Instead of the contextmenu event, You can also add the oncontextmenu handler into the HTML body tag to disable the right click. 

<body oncontextmenu="return false;">

Disabling F12 Key

The F12 key is a keyboard shortcut that is commonly used to open the developer tools in web browsers. Disabling this feature can prevent users from accessing the developer tools and viewing or modifying the webpage source code.


    document.onkeydown = function (e) {

        // disable F12 key
        if(e.keyCode == 123) {
            return false;

        // disable I key
        if(e.ctrlKey && e.shiftKey && e.keyCode == 73){
            return false;

        // disable J key
        if(e.ctrlKey && e.shiftKey && e.keyCode == 74) {
            return false;

        // disable U key
        if(e.ctrlKey && e.keyCode == 85) {
            return false;


From above code you can disable the F12 , Ctrl + Shift + ICtrl + Shift + J and Ctrl + U keys.

Disabling right-click and the F12 key can help protect your website content from unauthorized access or copying. However, it’s important to note that these techniques are not foolproof and can be bypassed by determined users.

Additionally, disabling right-click can also disable useful browser features such as opening links in a new tab. Therefore, it’s recommended to use these techniques judiciously and in combination with other security measures such as using watermarks or login systems to protect your website content.
