jQuery allows you to select HTML elements using CSS-like selectors. You can target elements by their IDs, classes, tags, and more. The selected elements become the targets for event attachment.
Attaching Event Handlers
You can use the .on() method to attach event handlers to selected elements. You specify the event type (e.g., "click", "keydown") and provide a function that will be executed when the event occurs.
When an event occurs, jQuery automatically passes an event object to the event handler function. This object contains information about the event, such as the type of event, the target element, and more.
jQuery supports event delegation, which means you can attach a single event handler to a parent element to handle events for its child elements. This is useful for dynamically added elements.
Preventing Default Actions
You can use the event.preventDefault() method within an event handler to prevent the default behavior of an event, such as following a link or submitting a form.
Removing Event Handlers
You can remove event handlers using the .off() method. This is particularly useful when you want to disable a specific handler from executing.
Multiple Event Handlers
You can attach multiple event handlers to the same element and event type. They will be executed in the order they were attached.
