What is the difference between $(window).load() and $(document).ready() functions in jQuery?
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.
You can try to run the following code to learn how to use to use $(document).ready() in jQuery:
<html> <head> <title>jQuery Function</title> <script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script> $(document).ready(function() { $("div").click(function() { alert("Hi!"); }); }); </script> </head> <body> <div id = "mydiv"> Click on this to see a dialogue box. </div> </body> </html>
You can try to run the following code to learn how to use $(window).load() in jQuery:
<!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("img").load(function(){ alert("Image successfully loaded."); }); }); </script> </head> <body> <img src="/videotutorials/images/tutor_connect_home.jpg" alt="Tutor Connect" width="310" height="220"> <p><strong>Note:</strong> The load() method deprecated in jQuery version 1.8.
