jqueryHow do I use jQuery to detect keycodes?

Answer

Using jQuery, you can detect keycodes by binding a keydown event to the document, and then using the event.which property to get the keycode of the pressed key.

$(document).keydown(function(event) {
    var keycode = event.which;
    console.log(keycode);
});

This code will output the keycode of the key pressed in the console.

Code explanation

1. $(document).keydown(function(event) - Binds a keydown event to the document
2. var keycode = event.which - Gets the keycode of the pressed key from the event object
3. console.log(keycode) - Outputs the keycode to the console
