Preventing Default Behavior

Stop built-in actions

Some events have default behaviors. Links redirect, forms submit, keys type. Use preventDefault() to stop these.

form.addEventListener("submit", function(event) {
  event.preventDefault(); // Don't submit normally
  // Handle form data with JavaScript
});

link.addEventListener("click", function(event) {
  event.preventDefault(); // Don't redirect
});
