DocumentService (jQuery.ready substitute)¶
The module TYPO3/CMS/Core/DocumentService
provides native JavaScript
functions to detect DOM ready-state returning a Promise<Document>
.
Internally the Promise is resolved when native DOMContentLoaded
event has
been emitted or when document.readyState
is defined already. It means
the initial HTML document has been completely loaded and parsed, without
waiting for stylesheets, images, and sub-frames to finish loading.
$(document).ready(() => {
// your application code
});
Above jQuery code can be transformed into the following using DocumentService
:
require(['TYPO3/CMS/Core/DocumentService'], function (DocumentService) {
DocumentService.ready().then(() => {
// your application code
});
});
