Invoke Multiple JavaScript Functions with a Single Onclick Attribute

Question: Would it be possible to trigger multiple JavaScript functions by utilizing the onclick attribute in HTML?

Answer:

Yes, it is feasible to execute several JavaScript functions with a single onclick attribute. To accomplish this, separate the function calls with semicolons within the onclick attribute, as seen in the following code:

onclick="doSomething();doSomethingElse();"

Prevention is Better Than Cure: Why You Should Avoid onclick

While the onclick attribute provides a straightforward way to attach JavaScript functions to HTML elements, it is generally considered a less desirable method. This is due to the concept of unobtrusive JavaScript, which promotes the separation of HTML and JavaScript responsibilities.

Unobtrusive JavaScript: A Better Approach

By separating JavaScript code from the HTML, you enhance flexibility, maintainability, and accessibility in your web applications. To achieve this, attach the event handler to the DOM node directly through JavaScript code:

document.getElementById("myButton").addEventListener("click", function() {
  doSomething();
  doSomethingElse();
});

This approach guarantees a cleaner and more structured separation of concerns, making it easier to modify and debug your code in the future.
