Can you list the difference between onload() and $(document).ready(function(){..}) functions in the using jQuery?

load() event is that the code included inside onload function will run once the entire page(images, iframes, stylesheets,etc) are loaded whereas the $(document). ready() event fires before all images,iframes etc.
There is no difference in functionality between your examples - they both bind to DOM ready. For reference, there are two points at which you can bind your jQuery code. The first will execute when the DOM is ready (both are equivalent): // full example $(document).
The ready() method is used to make a function available after the document is loaded. Whatever code you write inside the $(document ). ready() method will run once the page DOM is ready to execute JavaScript code.
Definition and Usage. The onload event occurs when an object has been loaded. onload is most often used within the <body> element to execute a script once a web page has completely loaded all content (including images, script files, CSS files, etc.).
the load event (a.k.a "onload") on the window and/or body element will fire once all the content of the page has been loaded -- this includes all images, scripts, etc... everything.
In contrast, jquery's $(document).ready(...) function will use a browser-specific mechanism to ensure that your handler is called as soon as possible after the HTML/XML dom is loaded and accessible. This is the earliest point in the page load process where you can safely run script that intends to access elements in the page's html dom. This point arrives earlier (often much earlier) than the final load event, because of the additional time required to load secondary resources (like images, and such).
