JAVASCRIPT EVENTS
Показать описание
In JavaScript, events are actions or occurrences that happen in the browser, such as a user clicking a button, pressing a key, hovering over an element, or loading a webpage. JavaScript can "listen" for these events and execute code in response. Here’s a breakdown of some key concepts related to events in JavaScript:
1. Event Types
Mouse Events: Triggered by mouse actions.
click: Fired when an element is clicked.
dblclick: Fired when an element is double-clicked.
mouseover: Triggered when the mouse is moved over an element.
mouseout: Triggered when the mouse is moved out of an element.
Keyboard Events: Triggered by keyboard actions.
keydown: Fired when a key is pressed down.
keyup: Fired when a key is released.
keypress: Deprecated in modern browsers but was used when a key is pressed and held.
Form Events: Used in forms.
submit: Fired when a form is submitted.
change: Triggered when the value of an input element changes.
input: Fired when the value of an input field is changed, even as the user types.
Window Events: Related to the browser window.
load: Fired when the entire page is loaded, including styles, images, and other resources.
resize: Triggered when the browser window is resized.
scroll: Fired when the user scrolls in an element.
2. Event Listeners
JavaScript uses event listeners to detect events. You can add an event listener to an element using:
addEventListener: Allows you to attach multiple event listeners to the same event.Onclick
Description: Triggered when a user clicks (usually with the left mouse button) on an element.
Usage: The most common event, often used for actions like submitting a form, opening a modal, or navigating to a different page.
Ondblclick (Double Click)
Description: Triggered when a user double-clicks on an element.
Usage: Less common but useful for actions like zooming in on images, editing text, or showing detailed views of items.
Oncontextmenu (Right Click)
Description: Triggered when a user right-clicks on an element. By default, it opens the context menu, but you can customize behavior.
Usage: Often used to create custom context menus or prevent users from copying content....#learnhtml5andcss3#WebDevelopment
