jQuery - What are differences between $(document).ready and $(window).load?

Question

What are differences between

$(document).ready(function(){
 //my code here
});

and

$(window).load(function(){
  //my code here
});

---

And I want to make sure that:

$(document).ready(function(){

}) 

and

$(function(){

}); 

and

jQuery(document).ready(function(){

});

are the same.

Can you tell me what differences and similarities between them?

Answer 1

$(document).ready(function() {
  // executes when HTML-Document is loaded and DOM is ready
  console.log("document is ready");
});


$(window).load(function() {
  // executes when complete page is fully loaded, including all frames, objects and images
  console.log("window is loaded");
});
