Web Reference: onclick is a DOM Level 2 (2001) feature. It is fully supported in all browsers: Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more. Both the second and third methods allow for inline/anonymous functions and both must be declared after the element has been parsed from the document.

The JavaScript code provided in the onclick attribute executes when the button is clicked.
