- Inline styles in moderation.
What happens after DOMContentLoaded?
DOMContentLoaded – the browser fully loaded HTML, and the DOM tree is built, but external resources like pictures and stylesheets may not yet have loaded. load – not only HTML is loaded, but also all the external resources: images, styles etc. beforeunload/unload – the user is leaving the page.
What is the difference between DOMContentLoaded and load?
Differences. The DOMContentLoaded event fires when all the nodes in the page have been constructed in the DOM tree. The load event fires when all resources such as images and sub-frames are loaded completely.
How do I know if I am DOMContentLoaded?
If you want to know “exactly” if DOMContentLoaded was fired, you could use a boolean flag like this: var loaded=false; document. addEventListener(‘DOMContentLoaded’,function(){ loaded=true; }
Does DOMContentLoaded wait for CSS?
DOMContentLoaded doesn’t wait for stylesheets to load provided that no scripts are placed after the stylesheet reference, . This is valid for all browsers supporting DOMContentLoaded.
What is the difference between OnLoad event and DOMContentLoaded event?
The load event is fired when the whole page has loaded, including all dependent resources such as stylesheets and images. 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.
On what event target should we listen for the DOMContentLoaded event?
The original target for this event is the Document that has loaded. You can listen for this event on the Window interface to handle it in the capture or bubbling phases.
Is there an event before DOMContentLoaded?
The DOMContentLoaded event is fired once Gecko finishes downloading the contents of the document, that’s the earlies point where you can access the complete DOM.
Is DOM ready?
DOM ready means that all the HTML has been received and parsed by the browser into the DOM tree which can now be manipulated. It occurs before the page has been fully rendered (as external resources may have not yet fully downloaded – including images, CSS, JavaScript and any other linked resources).
