javascript run after page load code example

Example 1: JavaScript that executes after page load

//two ways of executing JS code after page is loaded, use "DOMContentLoaded" when able

document.addEventListener("DOMContentLoaded", function(){
    //dom is fully loaded, but maybe waiting on images & css files
});

window.addEventListener("load", function(){
    //everything is fully loaded, don't use me if you can use DOMContentLoaded
});

Example 2: call javascript function after page load complete

//for jquery
//after document load
$(document).ready(function() {   //same as: $(function() { 
     alert("hi 1");
});
//after full window load including image src css file
$(window).load(function() {
     alert("hi 2");
});
