📚 Quick Study Guide

  • 🖱️ Mouse events are fundamental for user interaction in web development.
  • 👂 The main event listeners for mouse clicks are `onclick`, `onmousedown`, and `onmouseup`.
  • ☝️ The `onclick` event is triggered when a mouse click occurs on an element.
  • 👇 The `onmousedown` event is triggered when a mouse button is pressed down on an element.
  • 👆 The `onmouseup` event is triggered when a mouse button is released over an element.
  • 🎯 Event objects provide information about the event, such as the mouse coordinates.
  • 🛑 Preventing default behaviors (e.g., context menus) can be achieved using `event.preventDefault()`.
  • 💡 Different mouse buttons can be identified using the `event.button` property (0 for left, 1 for middle, 2 for right).
