- The readyevent occurs after the HTML document has been loaded, while theonloadevent occurs later, when all content (e.g. images) also has been loaded.
- The onloadevent is a standard event in the DOM, while thereadyevent is specific to jQuery. The purpose of thereadyevent is that it should occur as early as possible after the document has loaded, so that code that adds functionality to the elements in the page doesn’t have to wait for all content to load.
