Calling JavaScript Functions on Page Load Without Onload Attribute

The onload attribute, traditionally used to execute JavaScript functions on page load, presents a challenge when working with JSP fragments that lack a body element. Seeking an alternative solution, let's explore how to call JavaScript functions upon loading without using the onload attribute.

The window.onload eventlistener provides a viable alternative. This method binds a specific function to the onload event, ensuring its execution once the page has completed loading. For instance, consider the following code snippet:

window.onload = function() {
  yourFunction(param1, param2);
};

Within an anonymous function, this approach invokes your desired function, allowing you to pass parameters as needed. Notably, multiple functions can be executed within the anonymous function, providing flexibility in the code execution order.

This method bypasses the need for the onload attribute, making it suitable for cases like working with JSP fragments. It also offers a more structured approach to function execution compared to the onload attribute's direct JavaScript invocation.
