Run jquery after page is loaded

Eg:

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


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

Query 3.0 version

Breaking change: .load(), .unload(), and .error() removed

These methods are shortcuts for event operations, but had several API limitations. The event .load() method conflicted with the ajax .load() method. The .error() method could not be used with window.onerror because of the way the DOM method is defined. If you need to attach events by these names, use the .on() method, e.g. change $("img").load(fn) to $(img).on("load", fn).

$(window).load(function() {});

Should be changed to

$(window).on('load', function (e) {})

These are all equivalent:

$(function(){
}); 

jQuery(document).ready(function(){
});

$(document).ready(function(){
});

$(document).on('ready', function(){
})
