I think it will be awesome to use it alongside this article and beyond. Just focus your cursor anywhere in the app embedded below, and type any key to see the contextual information about it. You can also filter out the events you want by unchecking the checkboxes at the top. So give it a try:.
Among these events, the most used Keyboard event is or, should be keydown because:. In the example below, we are using event. The bowser's action to write the key characters into the textbox will not be performed in the case of keydown but it will continue to happen for keyup. With all that explanation, the keydown event is a clear winner and should become the most popular used key event type.
This is the billion dollar question! The shortest answer is, it depends. But on what? It depends on:. But before we get there, let's see a preview of some of the the useful properties and methods of the KeyboardEvent interface. The last three properties are deprecated and you should use the key property instead. The key property has the widest browser support. So as long as you are not using any of the older browsers, the event. In case you have to support an older browser, a better fallback would be the event.
If your code uses any of the deprecated properties and you have an opportunity to refactor that code, it is always better to go for it. The modifier keys are the special keys on your keyboard that modify the default behavior of the other keys.
Control , Shift , and Alt are some modifier keys. When a modifier key is combined with another key, you can expect a different action to occur. For example, if you press the key z , it is supposed to return the key and code for the letter z.
If you combine it with the modifier Control and press Control z , you will likely get an Undo operation. Let's see it with some more examples in the next section. The properties, event. We can combine multiple keys and perform actions based on the key combinations. The code snippet below shows how to combine the Control and z key to define an action:.
The table below shows a list of keys with the event. So what about virtual keyboards, like using our mobile phones or tablets or any other input devices? The specification says that if the virtual keyboard has a similar key layout and functionality to a standard keyboard, then it must result in an appropriate code attribute.
Otherwise, it is not going to return the right value. That's all for now. Thank you for reading this far! Let's connect. You can me on Twitter tapasadhikary with comments or feel free to follow.

It does work; I'm sure of it, because jQuery uses exactly that code : If you already have jQuery available, then just use it -- you don't need to have this in your own code. My point was that since jQuery already contains this line of code, he doesn't need it. He can just use event.
