This JavaScript code creates a simple drum kit application that responds to user clicks on drum elements or keypress events. Each drum element produces a unique sound, and the corresponding key on the keyboard triggers the same sound.
-
The code uses a loop to iterate through all the elements with the class "drum" and adds a click event listener to each element. When a drum element is clicked, the
makeSound()
andbuttonAnimate()
functions are called. -
The code also adds a keypress event listener to the whole document. When a key is pressed, the
makeSound()
andbuttonAnimate()
functions are called. -
The
makeSound()
function takes the clicked drum element or key as an argument and plays the corresponding sound based on the key value. It uses aswitch
statement to determine which sound to play based on the key value. -
The
buttonAnimate()
function takes the current key or drum element as an argument. It adds a CSS class called "pressed" to the corresponding drum element or key element. This class adds a visual effect to indicate that the drum or key has been pressed. After a brief delay of 100 milliseconds, the function removes the "pressed" class.
Example output when the "w" key or the corresponding drum element is clicked:
- The "w" key is pressed or the drum element with the letter "w" is clicked.
- The sound file "sounds/tom-1.mp3" is played.
- The corresponding drum element or key element receives the "pressed" class, creating a visual effect.
This code is a simple implementation of a drum kit using JavaScript. Feel free to modify and expand it according to your preferences and requirements.
