Use Onload or ready?

Question

In my application i am using

$(document).ready()

What is the difference between this and

$(document).onload()

Answer 1

The ready is triggered when only the DOM becomes ready while onload triggers when all resources of the page including DOM, images, frames, etc have loaded.

See:

$(document).ready vs. $(window).load

Note that ready lies with jQuery not raw javascript so I assume you know that and that way comparison seems logical.
