When to Use Document Ready and When Window Load in jQuery

$(window).load()

Use $(window).load(), when you want the code inside it to run only once the entire page is ready (not only DOM).  It executes when the page is fully loaded, including frames, objects and images

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()

Use the  $(document).ready() method when you want the code inside it to run once the page DOM is ready to execute JavaScript code.
