$( document ).ready()

A page can’t be manipulated safely until the document is «ready.» jQuery detects this state of readiness for you. Code included inside $( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute. Code included inside $( window ).on( «load», function() < . >) will run once the entire page (images or iframes), not just the DOM, is ready.

// A $( document ).ready() block.
$( document ).ready(function( )
console.log( "ready!" );
>);

Experienced developers sometimes use the shorthand $() for $( document ).ready() . If you are writing code that people who aren't experienced with jQuery may see, it's best to use the long form.

// Shorthand for $( document ).ready()
$(function( )
console.log( "ready!" );
>);

You can also pass a named function to $( document ).ready() instead of passing an anonymous function.

// Passing a named function instead of an anonymous function.
function readyFn( jQuery )
// Code to run when the document is ready.
>
$( document ).ready( readyFn );
// or:
$( window ).on( "load", readyFn );

The example below shows $( document ).ready() and $( window ).on( "load" ) in action. The code tries to load a website URL in an and checks for both events:

html>
head>
script src="https://code.jquery.com/jquery-1.9.1.min.js"> script>
script>
$( document ).ready(function( )
console.log( "document loaded" );
>);
$( window ).on( "load", function( )
console.log( "window loaded" );
>);
script>

JavaScript DOM Ready

JavaScript DOM Ready

  1. Use the jQuery ready() Function to Call Functions When DOM Is Ready
  2. Vanilla JavaScript Approach to Call Functions When DOM Is Ready

The loading of a website starts from downloading the HTML document. Once the HTML doc is downloaded, the HTML is parsed, and required assets are downloaded. After the HTML is parsed, the DOM and CSS are rendered in parallel. After this, the browser takes care of the JavaScript onload functions. This is the timeframe we want to call functions because HTML, CSS, DOM are correctly rendered. This tutorial teaches how to call a function when the DOM is ready.

Use the jQuery ready() Function to Call Functions When DOM Is Ready

The ready() function in jQuery executes the code when the DOM is ready. It waits for all the elements to be fully loaded and then tries to access and manipulate them. We can select the document element, an empty element to call a function, or even directly call a function.

$(document).ready(function()   // callback function / handler  >); 

It is a full cross-browser compliant method and can be called from anywhere in the HTML code.

Vanilla JavaScript Approach to Call Functions When DOM Is Ready

We can create the JavaScript equivalent of jQuery’s ready() function by using the DOMContentLoaded event. We can add an event listener for DOMContentLoaded and call our desired function with that event listener. But there is one catch, the callback will not be triggered if the event has already occurred. So, we take care of this condition by checking the ready state of the document object.

const callback = function() >;  if (document.readyState === "complete" || document.readyState === "interactive")   setTimeout(callback, 1); > else   document.addEventListener("DOMContentLoaded", callback); > 
  • Use the window’s onload attribute to call the JavaScript function.
  • Use the body’s onload attribute to call the JavaScript function. This method can be terribly slow as it waits for every single element to be loaded.
  • We can call the function to be executed from the end of the body. At the end of the body, DOM is appropriately rendered and ready. So, there are no issues with function calls related to any element. It works much faster than the body onload handler because it does not wait for the images to be loaded completely.
