Step 1 of 5

Understanding Click Events

Click events are the most common type of event in web development. They happen when a user clicks on an element with their mouse or taps on a touchscreen.

When Clicks Happen:

  • ✓ User clicks a button
  • ✓ User clicks a link
  • ✓ User clicks an image
  • ✓ User clicks anywhere on the page
  • ✓ User taps on touchscreen (mobile)

Why Click Events Matter

Click events power most user interactions:

  • Submit forms
  • Open menus
  • Like posts on social media
  • Add items to shopping cart
  • Play/pause videos
  • Expand/collapse content
// Basic click event
const button = document.querySelector('button')

button.addEventListener('click', function() {
alert('Button clicked!')
})
