The callback function currently only has the 'use strict' statement and a console log to verify that the file is correctly linked to the HTML page. It’s pretty straightforward, we add an event listener to the document that waits until the DOM is fully loaded and then calls the callback function. Here is quick breakdown of the JavaScript content we initially have.

You can download the initial project files here or you can create your own if you like to have it made your own way. In order to focus only on JavaScript, I’ve created complete HTML and CSS for the project, and linked the JavaScript file which only contains a console log to make sure it works. In the example that we will build, we will make the background image for an element on the page to change based on the key sequence typed in by the user. Basically, when the user types a key combination, the game enables some benefits to the user, like more ammo, more health, invulnerability, etc. My idea was to use the key sequences that are used as cheat codes in an old FPS game, Doom and Doom 2. We will also add some text updates as well just to make the demonstration richer and to provide more info to the user. So we are basically dealing with the styling, nothing too fancy. What are we building?įor this article I’ve decided to make an element on the page change its background image based on the sequence of keys the user types. If you are not familiar with those, check the provided links to learn more. So, when the user presses a key combination, the web page might show some content, like opening a menu or a modal, it can change the styling of the page or perform any other action you can imagine which is within the JavaScript capabilities.īefore we start I just want to point out that I’m using some ES6 features like const and let, the spread operator (.

In this article, we will be looking into how we can use JavaScript to react to the keyboard events, specifically, how to react to the specific key sequence that the user types. With JavaScript we can react when a user clicks on a specific part of the page, when a key is pressed, when mouse moves, when the page is loaded, when an element gets focused, etc.įor the list of all JavaScript events available check this MDN page.Įven though today JavaScript can be used to do so much more, this basic feature of adding interactivity to the web page is still widely used to provide the users with rich and interesting experiences. In fact, that was the very idea of JavaScript when it appeared, to make web pages dynamic by adding some interactivity to them. One of the most used features of JavaScript is its ability to react on various events that may occur while the user interacts with the web page. Photo by Aleksandar Cvetanovic on Unsplash
