Executing Functions on Page Load Without Body Tag Initialization

The question presents a scenario where a user seeks to execute a function when a page loads, avoiding the use of the tag for initialization. While the attempt to use window.onload = codeAddress; was unsuccessful, this article will provide a solution to this challenge.

The provided code demonstrates the proper usage of the window.onload event listener. When the page is fully loaded and rendered, the window.onload event is triggered, allowing the execution of the specified function. By assigning the codeAddress function to the window.onload property, the function will automatically execute when the page loads.

This is exemplified in the provided code snippet:

function codeAddress() {
  alert('ok');
}

window.onload = codeAddress;

When the page loads, the codeAddress function will be executed, displaying an alert with the message "ok." This illustrates the successful execution of a function upon page load without the need for tag initialization.
