You may view and copy all the code for this exercise at. Now our application looks like this ( Figure 3):įigure 3: The appearance of the finished app in your browser should look somewhat like this įont-family: 'Shadows Into Light', cursive Ĭode snippet 11: This code, inside the element of sound.html, gives some visual style to the app Make sure it’s inside the element in your document. After the closing title tag, add the style code in code snippet 11. Just for fun, let’s add a little CSS as a finishing touch to make the app look better. In the browser your app should appear similar to Figure 2.įigure 2: When you test your application in your browser, you should see something like this Ĭonst mySound = document.getElementById("sound") Ĭonst correctButton = document.getElementById("correct") ĬorrectButton.addEventListener("click", function()Ĭode snippet 10: This is the complete audio.html fileĪgain, test your application and you should hear a sound corresponding to correct and incorrect answers. ![]() The JavaScript in code snippet 6, between the existing tags, will do the trick. We’re going to want to play the “Correct Answer.mp3” when that button is pushed. Note that for now, the correct answer has been given the id “correct”. Who played the character of Harry Potter in the movie series?Ĭode snippet 5: Add this code below the tag-this is the assessment question. We can add the code for the assessment question right below the closing audio tag. In this example, our sounds are going to play based on a user's response to a simple assessment. This will allow us to pull the element into our JavaScript code. ![]() In addition to adding the tags, we’ve added an id attribute to the element. Ĭode snippet 4: Add tags to the basic sound.html document to allow inserting JavaScript Let’s start with our basic document structure and add the tags so we can insert JavaScript. Now we’re going to modify our code to play sounds in reaction to correct and wrong answers given by the user. Let’s bring in JavaScript to provide more options. Even if this method DOES work in your browser, it does not offer the necessary amount of control for you as a digital learning developer. Note that due to the potential for abuse of autoplay, this has been disabled in many browsers. Ĭode snippet 3: These lines cause the sound file to play when the page opens We can alter the code slightly so the sound plays when the page opens and the player does not appear. With the setup above, the sound is in a player controlled by the user. For the most part, we’d want to play sounds in reaction to some user action or, perhaps, as part of an instructional segment. Of course, this is not optimal for digital learning. This player also has a volume control and a scrubber, which is only useful for longer audio segments. If you press the play icon, you’ll hear the sound. What you see in the browser window is the standard audio player. Open your HTML file in your browser and you’ll see something similar to Figure 1.įigure 1: When you open sound.html, this is what you should see Ĭode snippet 2: Add these audio and source elements to sound.htmlīelieve it or not, that’s all you need. Inside the body of your document, let’s add the audio and source elements. (It is easiest to have your mp3 file and your HTML file in the same folder at this point.) The audio element also requires that you embed a element that is pointed at the file you want to play. The audio element determines exactly how audio will be played. Not surprisingly, the element that controls audio within an HTML document is the element. Ĭode snippet 1: Create this JavaScript file and name it “sound.html” We’ll enter the standard HTML basic document structure first. ![]() Let’s start by opening a text editor and creating a file called sound.html. If you’d like to file along, download “Correct Answer.mp3” from. Let’s start with the easiest implementation. Luckily the API for coding sound with HTML5 and JavaScript is fairly accessible and can even be mastered by beginning coders. However, when authoring with HTML5 and JavaScript, producing sound requires coding. Every contemporary authoring environment integrates sound. Sound can be used to give feedback, add drama, and even make learning content more accessible. Audio, when used correctly, can be an important component in digital learning content. ![]()
