Practice implementing DOM Events using vanilla Javascript

FunWithDOMEvents

• Level: Beginner
• Description: Practice implementing DOM events using vanilla Javascript

Lesson

To implement DOM events, use the process flow:

1. Identify the element you are watching/targetting
2. Set an event listener on it with what is being listening for and reference the function that should be invoked when the even occurs
3. Write a function with all of the things that should happen once the event is triggered

Challenges

• Challenge Zero: Make the “play” button move to random locations as you click it
• Challenge One: When you double-click a piece of text, make the text “disappear”
• Challenge Two: When you mouseover the button, the background color of it changes
• Challenge Three: When you copy (command + c) the title “Gotta catch em all,” an alert appears warning you not to
• Challenge Four: When you right click on any element in the body, the background changes to a different image

Example

let playButton = document.getElementById("play-button");
playButton.addEventListener("click", myEventHandler);

function myEventHandler() {
  alert ("Hello World!");
}

Relevant DOM Events

• click → “click”
• double click → “dblclick”
• mouse over → “mouseover”
• copy → “copy”
• right click → “contextmenu”
