Javascript Event Listeners List – 2023

Introduction

As a web developer, I have been working with Javascript for several years now. One of the most important things I have learned is the concept of event listeners. In this article, I will share my personal experience with Javascript event listeners and provide a comprehensive list of available options.

What are Javascript Event Listeners?

Javascript event listeners are functions that wait for a specific event to occur and then execute a task. For example, if a user clicks on a button, an event listener can be used to detect the click and perform an action.

List of Javascript Event Listeners

Here is a list of commonly used Javascript event listeners:

click
mouseover
mouseout
keydown
keyup
load
unload
submit
resize
scroll

Using Event Listeners

To use an event listener in Javascript, you first need to select the element you want to attach the listener to. This can be done using the document.getElementById() method or by using query selectors.

Once you have selected the element, you can add an event listener using the addEventListener() method.

Here is an example of how to add a click event listener to a button:

   let button = document.getElementById("myButton");   button.addEventListener("click", function() {    // Perform action here   });

Question and Answer

Here are some common questions and answers about Javascript event listeners:

What is the purpose of Javascript event listeners?

Javascript event listeners allow you to detect user actions and respond accordingly. This can be used to create interactive web pages and improve user experience.

How do you remove an event listener?

You can remove an event listener using the removeEventListener() method. This method requires the same parameters as the addEventListener() method – the event type and the function to be removed.
