It is generally not recommended to disable keyboard shortcuts or modify the default behavior of browser controls, as this can interfere with user accessibility and can also be bypassed using browser extensions or custom user settings. However, if you want to prevent the use of certain keyboard shortcuts (such as Ctrl+C for copy or Ctrl+V for paste), you can use JavaScript to listen for keydown events and prevent the default behavior of the event when certain keys are pressed. Here is an example code that prevents the use of Ctrl+C and Ctrl+V:
document.addEventListener('keydown', event => {
if (event.ctrlKey && (event.key === 'c' || event.key === 'C' || event.key === 'v' || event.key === 'V')) {
event.preventDefault();
}
});
This code adds an event listener to the keydown
event, which is triggered when a key is pressed. The ctrlKey
property of the event object is used to check if the Ctrl key is being held down, and the key
property is used to check if the pressed key is 'c' or 'v'. If these conditions are met, the preventDefault()
method is called to prevent the default behavior of the event (which is to copy or paste text).
Again, it is generally not recommended to disable browser controls or keyboard shortcuts, as this can make it difficult for users to navigate and interact with your web page.
