Hello! Are you ready to unravel JavaScript events? In today's lesson, we will focus on understanding events and how JavaScript incorporates them into an HTML page. We'll delve into events, how they generate action, and event handlers. Let's get started!
Before we jump further into the lesson, let's delve into the HTML <button>
tag and how it interacts with the onClick
attribute.
The <button>
tag in an HTML document creates a clickable button that performs a specified action when a user clicks on it. Imagine it as a doorbell to a house - when pressed, it triggers a response.
The onClick
attribute, on the other hand, is an event attribute. It is used within HTML tags to call a JavaScript function when an onclick
event (the button click in our case) occurs.
Let's see an example of how to use these two together:
In this code, we have a button that says "Click me!". When you click this button, an alert box with the message "You clicked me!" will pop up on your screen. This response is triggered because of the onClick
attribute in the button tag that activates the JavaScript function alert('You clicked me!')
.
