Eerder was deze modus al ge\u00efmplementeerd in Chrome 76 en Firefox 75 voor afbeeldingen. Nu hebben de ontwikkelaars van Chrome een nieuwe stap gezet en de mogelijkheid voor het uitstellen van het laden van iframe-blokken toegevoegd.<\/p>\n<p>Voor het beheer van uitgestelde pagina-inlading in de &lt;iframe&gt;-tag is de attribuut &lt;loading&gt; toegevoegd, dat waarden kan aannemen zoals &lt;lazy&gt; (uitgestelde inlading), &lt;eager&gt; (direct inladen) en &lt;auto&gt; (uitgestelde inlading naar keuze van de browser wanneer de modus is ingeschakeld <noindex><a rel=\"nofollow\" href=\"https:\/\/blog.chromium.org\/2019\/04\/data-saver-is-now-lite-mode.html\">Lite<\/a><\/noindex>). Het wordt verwacht dat het uitstellen van het laden het geheugengebruik kan verminderen, het dataverbruik kan verlagen en de snelheid van het initi\u00eble openen van pagina's kan verhogen. Bijvoorbeeld, met de inschakeling van deze nieuwe modus zullen blokken met advertenties en widgets van Twitter, Facebook en YouTube niet direct worden geladen als ze niet zichtbaar zijn voor de gebruiker, totdat de gebruiker de pagina scrolt naar de positie v\u00f3\u00f3r deze blokken. <\/p>\n<p> <center><noindex><a rel=\"nofollow\" href=\"https:\/\/webdev.imgix.net\/iframe-lazy-loading\/iframe-lazyloading.png\"><img decoding=\"async\" alt=\"In Chrome is ondersteuning voor het uitstellen van het laden van iframe-blokken toegevoegd.\" src=\"\/wp-content\/uploads\/2020\/07\/455b9a18794d16782578f36a5be4025b.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/a><\/noindex><\/center><\/p>\n<p>Volgens de ontwikkelaars zal het uitstellen van het laden gemiddeld 2-3% van het dataverbruik besparen en het aantal <noindex><a rel=\"nofollow\" href=\"https:\/\/web.dev\/fcp\/\">initi\u00eble weergaven<\/a><\/noindex> met 1-2% verminderen en de <noindex><a rel=\"nofollow\" href=\"https:\/\/web.dev\/fid\/\">vertraging voor invoer beschikbaarheid<\/a><\/noindex> met 2%. Voor specifieke websites zijn de wijzigingen meer zichtbaar. Bijvoorbeeld, het inschakelen van uitgestelde inlading van het YouTube-blok leidt tot een vermindering van de te laden gegevens met ongeveer 500KB, Instagram \u2014 met 100KB, Spotify \u2014 met 500KB, Facebook \u2014 met 400KB. In het bijzonder heeft het toepassen van uitgestelde inlading van YouTube-blokken op de website Chrome.com de laadtijd op mobiele apparaten met tot 10 seconden verminderd, waardoor de beschikbaarheid van pagina's voor interactie en het initi\u00eble geladen JavaScript-grootte met 511KB is verkort. <\/p>\n<p><center><noindex><a rel=\"nofollow\"
