Running javascript code on page load, without using the onload tag

Question

How can I run a JavaScript code when the page loads without using the onload tag?

I\'m trying to run this script:

Answer 1

Like this:

window.onload = function WindowLoad(event) {
    alert("Page is loaded");
}

Edit: if some other code is also using window.onload after that script then it will be "overwritten" - to make sure it's executed (and abort any other onload) put it in the bottom of the page.

Edit 2: On second thought, you better add onload listener instead of overwriting it:

This will prevent any conflicts with existing code and is more cross browser as far as I can tell.
