26 lip 2024 · The load event is fired when the whole page has loaded, including all dependent resources such as stylesheets, scripts, iframes, and images, except those that are loaded lazily. This is in contrast to DOMContentLoaded , which is fired as soon as the page DOM has been loaded, without waiting for resources to finish loading.

The onload event can be used to check the visitor's browser type and browser version, and load the proper version of the web page based on the information. The onload event can also be used to deal with cookies (see "More Examples" below).
window.onload just runs when the browser gets to it. window.addEventListener waits for the window to be loaded before running it. In general you should do the second, but you should attach an event listener to it instead of defining the function.
26 lip 2024 · The load event fires for elements containing a resource when the resource has successfully loaded. Currently, the list of supported HTML elements are: <body> , <embed> , <iframe> , <img> , <link> , <object> , <script> , <style> , and <track> .
The onload attribute fires when an object has been loaded. onload is most often used within the <body> element to execute a script once a web page has completely loaded all content (including images, script files, CSS files, etc.).
The load event occurs when the document has been completely loaded, including dependent resources like JavaScript files, CSS files, and images. The <img> and <script> elements also support the load event. Use the addEventListener() method to register an onload event handler.
To execute code when a user clicks on an element, add JavaScript code to an HTML event attribute: onclick= JavaScript. Examples of HTML events: When a user clicks the mouse. When a web page has loaded. When an image has been loaded.
