Momwe mungapangire WordPress yaulesi kutsegula JavaScript kuti ifulumizitse kutulutsa masamba?

WordPressKutsitsa kwaulesi kwa JavaScript kuti mufulumizitse njira zoperekera masamba.

Kodi katundu wa JavaScript's Defer ndi chiyani?

Aliyense ayenera kuti anakumanapo ndi izi:

Pali zolemba za N m'mutu, ndipo zolembedwazo zikatsitsidwa, zolemba zamasamba zimatsekedwa, zomwe nthawi zambiri zimakhala zopanda kanthu.

Zachidziwikire, titha kuzungulira izi poyika script mu code source m'munsimu.

Komabe, malo ena otukuka ovuta angapangitse kuti ntchitoyi ikhale yovuta kwambiri.

Pakadali pano titha kugwiritsa ntchito Defer katundu, yomwe ndi malo osowa kwambiri mu JavaScript.

Mwina simungagwiritse ntchito, koma mutawerenga mawu oyambawa, ndikukhulupirira kuti simudzawasiya.

Ntchito yake yayikulu ndikulola kuti script idutse tsamba lonse litatsitsidwa, m'malo moligawanitsa, lomwe limapereka liwiro lathunthu lazolemba zomwe zimangokhala ndi JavaScript yoyambitsa zochitika.

Inde, ngati script tag ili ndi defer defer, idzachitidwa pambuyo polemba tsamba la HTML ngakhale itayikidwa pamutu, zomwe ziri zofanana ndi kuika script pansi pa tsamba.

Zachidziwikire, kugwiritsa ntchito kuchedwa kulinso kochepa, nthawi zambiri samalani mfundo za 2:

1) Musayimbire lamulo la document.write mumtundu wa deferred defer script block;

• Chifukwa document.write idzatulutsa zotsatira zachindunji.

2) Osagwiritsa ntchito zosintha zapadziko lonse lapansi kapena ntchito mu Defer scripts, kuphatikiza zolemba zilizonse zomwe zachitika posachedwa.

Onjezani mawonekedwe a Defer ku script yomwe imagwiritsidwa ntchito mu WordPress

Mu WordPress, tingawonjezere bwanji mawonekedwe a Defer ku zolemba zomwe zimagwiritsidwa ntchito ndi WordPress?

Titha kuwonjezera kachidindo kotsatira ku fayilo ya mutu wapano wa function.php ▼

add_filter( 'clean_url', 'wpcwl_defer_script',11,1);
function wpcwl_defer_script( $url ){
if(strpos($url, '.js') === false){
return $url;
}

return "$url' defer='defer";
};

• Khodi yomwe ili pamwambapa imagwira ntchito, molingana ndiJavaScript code yoyambitsidwa ndi WordPresszidzakhala zogwira mtima.

Njira zopewera

Live Preview Management ikhoza kuwonetsa opanda kanthu:

Ngati mugwiritsa ntchito nambala yomwe ili pamwambapa, mutsegula kasamalidwe ka nthawi yeniyeni (Mawonekedwe → Sinthani Mwamakonda Anu), ikhoza kuwonetsa kuti ilibe kanthu, kotero chonde igwiritseni ntchito moyenera.

Mukayang'anira zowonera zenizeni nthawi yeniyeni ikufunika, perekani ndemanga pa code yomwe ili pamwambapa, ndikuchotsani kachidindo komwe mwafotokozera mukamaliza makonda.
