Answers for "javascript function call after page load"


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

call javascript function after page load complete

document.addEventListener('readystatechange', event => { 

    // When HTML/DOM elements are ready:
    if ( === "interactive") {   //does same as:  ..addEventListener("DOMContentLoaded"..
        alert("hi 1");

    // When window loaded ( external resources are loaded too- `css`,`src`, etc...) 
    if ( === "complete") {
        alert("hi 2");
