Can I Call Multiple JavaScript Functions within a Single onclick Event?

Multiple JavaScript Function Invocation in Onclick Event

The onclick event attribute is commonly used to trigger a JavaScript function in response to a button click or element interaction. However, there may be scenarios where you want to invoke multiple functions sequentially.

Can You Call Multiple JavaScript Functions in Onclick?

Yes, you can call multiple JavaScript functions in the onclick event attribute using the following syntax:

onclick="function1(); function2();"

This will execute both function1 and function2 in sequence when the element is clicked. However, it's important to note that it's generally not recommended to use this approach.

Better Practice: Event Handlers in Javascript Code

A more recommended approach is to separate the function call from the HTML and attach the event handler through JavaScript code. This technique is known as "unobtrusive JavaScript."

<button>

const btn = document.getElementById("btn");
btn.addEventListener("click", () => {
  doSomething();
  doSomethingElse();
});

This approach:

• Enhances code maintainability by keeping HTML and JavaScript separate.
• Allows you to add or remove event listeners dynamically.
• Prevents the page from becoming overloaded with inline JavaScript in the HTML.

In summary, while it's possible to call multiple JavaScript functions in the onclick event attribute, it's generally advisable to use unobtrusive JavaScript and handle events through code to improve code organization and flexibility.
