Event handlers are the most popular scripting language for web applications. Anrdoid Event Handler methods can be used in almost every situations where you want to use a javascript event. They are very useful because they can be easily integrated in various projects and tools.

With the emergence of Anrdoid Event Handler methods, we have grown more comfortable with the use of events and have started to embrace these concepts for our everyday needs.

Some of the most popular events are:

  • Launch/press event
  • Product launch event
  • Achieved a goal event
  • Announcement event (Appointment, Event, etc.

Event handlers are a part of the JavaScript language that generates events that occur within a page. A page is defined by JavaScript and in most cases, it is either the DOM (Document Object Model) or an HTML document. For example,  the DOM defines the elements contained within that document and an event handler handles the events that are triggered from within these elements. Events can be triggered from anywhere on a page within the HTML or any JavaScript code. In this article we will be discussing about three different methods for triggering events on our pages: global, local and with event handlers applied to specific DOM elements.

As a result of the user's interaction with the graphical user interface components, events are generated. Clicking a button, moving the mouse, typing a character, selecting an item from a list, and scrolling the page are examples of behaviours that cause an event to occur.

JavaScript events are a powerful tool for developers. They can be used to communicate with the user, update the UI and much more. As a developer, you can use JavaScript events to make your code work in different situations.
