What is the difference between $(window).load() and $(document).ready() functions in jQuery?

jQueryWeb DevelopmentFront End Technology

Both the methods are used in jQuery. Let’s see what purpose they fulfill.

$(window).load()

The code which gets included inside $( window ).on( "load", function() { ... }) runs only once the entire page is ready (not only DOM).

Note: The load() method deprecated in jQuery version 1.8. It was completely removed in version 3.0. To see its working, add jQuery version for CDN before 3.0.

$(document).ready()

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.
