We often nest related DOM elements when we write our markup. For instance, we may have an div containing an img, an h2, and a p tags

  
My item
 
Item description
 

Suppose we wanted to allow the user to click anywhere inside of this div. If we were simply navigating the user to a new page, an a tag with a properly set href would be sufficient. But if we want to perform some other action on the current page, we’ll want to use JavaScript to listen for click events to the entire div and all of it’s children.

Fortunately, we don’t have to listen and respond to a click on each DOM element – div, img, h2, and p. We only have to listen to events on the parent! This is due to event bubbling.

When an event occurs on any DOM element on a page, the event is bubbled up through it’s parent elements triggering the event on each. So in our example above, if a user clicks on the p element, the click event will be triggered on the p followed by the parent div following by the parent of the div all the way to the document object.

As described in the previous step, the event is first triggered on the target element and then on it’s parents moving up the chain. We can prove this with a quick example.

Suppose we have the following markup:

We can set a click event listener on each div like this:

$(function() { $("#outer").on('click', function() { console.log('#outer click event triggered'); }); $("#middle").on('click', function() { console.log('#middle click event triggered'); }); $("#inner").on('click', function() { console.log('#inner click event triggered'); }); });

If I click on the inner div, #inner, I will see this in the console logs:

#inner click event triggered #middle click event triggered #outer click event triggered

Even though it appears that they are logged at the same time, the order is important. The event was triggered first on the inner div, followed by the middle div, followed by the outer div.

Suppose I click on the middle div.

#middle click event triggered #outer click event triggered

You probably assumed the output. The middle div was triggered first followed by it’s parent outer div. The event on the inner div wasn’t triggered.

In JavaScript, events have a target attribute to identify which DOM element was the target of the event. When we listen for events on a specific DOM element we can provide a callback function that is called when the event is triggered. This callback function takes the event as its first argument. This event object contains the target of the event. Here’s a quick example showing how to access the target.

The markup:

Click me

And the JavaScript:

$(function() { $("button").on('click', function(event) { console.log(event.target); }); });

Note: Even though we are using jQuery, as it stands the event.target attribute will be a vanilla JavaScript DOM object, not a jQuery object.

In the above example, the target would be the actual button that was clicked.

When we get into nested DOM elements this becomes a little bit more interesting. Take our example from the previous step. Suppose we log the target for each div.

$(function() { $("#outer").on('click', function(e) { console.log($(e.target).attr('id'), $(this).attr('id')); }); $("#middle").on('click', function(e) { console.log($(e.target).attr('id'), $(this).attr('id')); }); $("#inner").on('click', function(e) { console.log($(e.target).attr('id'), $(this).attr('id')); }); });

The above code simply logs the id of the target and the id of this – this being the element we’re listening to. A click on the #inner element will log this:

inner inner inner middle inner outer

Each line shows target this.

As expected, the target doesn’t change. Even though the event is bubbled up and triggered on parent elements, the target remains the actual element that was clicked on. However, this provides access to the element we’re listening to. As we see, inner inner is first showing that the event on the #inner element was triggered first, and obviously #inner is the target as well.

Sometimes you’ll want to stop an event from bubbling all the way to the top. Maybe you know for sure you’re finished processing the event, or perhaps in some case you don’t want the event to be triggered on the parent.

We can stop bubbling with event.stopPropagation().

Taking the example we’re using throughout this guide, we can test this out:

$(function() { $("#outer").on('click', function(e) { console.log("#outer click event triggered"); }); $("#middle").on('click', function(e) { console.log("#middle click event triggered"); }); $("#inner").on('click', function(e) { console.log("#inner click event triggered"); e.stopPropagation(); }); });

This is similar to what we saw before except that we’ve added e.stopPropagation() to the callback for the #inner div. Before, a click on the #inner element bubbled up to the parent elements and logged 3 lines, but this time it stops with the target and logs:

#inner click event triggered

Game Boys can be upgraded with an amazing variety of custom shells. In 2018, you don’t have to look hard to find third party vendors selling Game Boy shells. Most of them are aftermarket shells, created with the modern modding community in mind.

However, it is possible to locate original hardware. Auction websites and used gaming stores sell old devices and individual Game Boy components. This is great for restoration projects or those who just prefer original hardware. If you want to learn more about customizing your shell, visit our Game Boy shell replacement guide.

Another common mod you’ll find in the community is custom buttons. Upgrade your Game Boy with brand new controls! They work just like the old ones, but you can choose a different color if you like.

Third party vendors sell many custom color buttons to match the wide array of replacement shells. Replacing the buttons is just as easy as replacing the shell with half the work! Just open up the Game Boy, remove the front motherboard, and swap out the buttons. While you have that Game Boy open, it’s a great time to fix any button sticking issues—visit our guide to learn how to fix sticky Game Boy buttons.

Finding an old Game Boy is awesome. Wasting time to find a lamp to sit under is not. That’s why we have the Game Boy backlight mod! After almost 30 years, you can finally install a working light to play your original Game Boy in the dark.

This mod is a little bit involved and could potentially ruin the original screen. You may want to avoid using any sentimental hardware. But if you think you’re ready, so do we. Head over to our Game Boy backlight mod guide to get started!

A small side effect of installing the backlight is speaker whine — I’ve written a guide to help you fix that.

Backlighting an original Game Boy screen has a direct impact on pixel contrast. Rotating the polarizing film can cause the pixels to invert—some modders do this intentionally. For an ideal display, the pixels need to be inverted twice.

The modding community tackles this issue by means of bivert chip mods. The installation of these chips inverts the signal information for dark and light pixels. This small difference improves the contrast and visibility on the screen. As a side effect from this mod, the contrast wheel now works backwards.

I wrote a complete guide on how to perform the bivert chip mod.

Customizing the bezel on a Game Boy can add an incredible touch to your modding project. The original screen bezels were made of plastic. But you can find a wide variety online, including high quality bezels made of glass.

The original Game Boy was released with a gray bezel. But you’ll find a rainbow of options online—including custom printed graphics. Your only limit is your imagination when it comes to custom bezel replacement.

Game Boy screens are more than necessary, they’re iconic. But there comes a time in every modders like when you realize that maybe it would be pretty cool to install that 3″ aftermarket screen. Just for funsies, right?

Or maybe you’ve bricked your original Game Boy screen in a failed attempt to install a backlight. Repurpose old components and create your very own “frankenboy”. Add a custom after market screen and throw it in a custom shell while you’re at it. There’s nothing wrong with taking advantage of modern day upgrades.

Original Game Boy audio is so classic, fans have created genres of music based on it. Chiptunes are built on the fundamental sounds created by the Nintendo Game Boy. But what if you wanted to bring out the best of these sounds?

If you’re into high quality audio, this mod is for you. This mod upgrades your Game Boy to let more power through the sound system. Amplify those bass tones and bring out the best audio in your Game Boy. Ready to get started? Check out our Game Boy bass boost guide here.

This is everything! Okay—not everything. There’s always one or two Game Boys hiding around the house somewhere. But this is definitely a huge chunk of the collection! If you had a Game Boy as a child, you probably see one just like it here. The full picture doesn’t do it justice. Let’s dig in and check out the highlights of the collection.

The original Game Boy design is iconic in the gaming world. This was the first model created for the Game Boy line. They all have the classic offwhite/cream shell. A couple have yellowed more than others, this is likely due to poor storage conditions.

Before the Game Boy Color—there were colored Game Boys! The Play It Loud series brought a much-needed splash of color to the original Game Boy design. We’ve almost got every Play It Loud color: blue, red, yellow, green, black, and transparent. The only one missing is white.

The original Play It Loud shells typically have a gray bezel, gray buttons, and black text. On the black Play It Loud shell, the Game Boy text is a pink/red color. We managed to snag a couple in the original retail boxes. One of these boxes had the original Game Boy pamphlets!

One of the green Play It Loud Game Boys has been backlit, this makes the screen look darker in comparison. One of the unmodded Game Boys came with the original booklets, a Nintendo Power ad, and a really awesome Play It Loud poster. I love finding original documentation. It’s like unfolding pure nostalgia.

The clear Game Boys are so cool. They are just as exciting today as they were 20+ years ago. I’m really happy to have a few good clear shells in the collection. One of the boxes still had the Play It Loud box art tucked inside. There’s just something wicked about seeing the Game Boy guts while you play. These shells are some of my absolute favorites.
