This article uses jQuery to call a function after a page is loaded.
Table of contents:
P.S Tested with jQuery 3.7.1
1. $(document).ready()
In jQuery, the code inside the $(document).ready() method will run once when the Document Object Model (DOM) is ready, equivalent to the DOMContentLoaded event in plain JavaScript.
$(document).ready(function() {
console.log('The page has loaded!');
// Your jQuery code goes here
});
Or, using the shorthand for .ready():
$(function() {
console.log('The page has loaded!');
// Your jQuery code goes here
});
2. jQuery call a function after page loaded
Below is a complete jQuery example to call a function to replace the text after loading the page (DOM ready).
