WordPressUkulayisha ukonqena kweJavaScript ukukhawulezisa unikezelo lwephepha.

Yintoni uphawu lweJavaScript's Defer?

Wonke umntu usenokuba ukhe wadibana nale meko:

Kukho imibhalo ye-N entloko, eya kuvala unikezelo lwephepha xa ulayisha izikripti, ezidla ngokungabi nanto.

Ngokuqinisekileyo, sinokuyicombulula le ngxaki ngokubeka iskripthi kwikhowudi yomthombo kwindawo esezantsi.

Nangona kunjalo, ezinye iimeko zophuhliso ezintsonkothileyo zinokwenza lo msebenzi ulula ube nzima kakhulu.

Kweli nqanaba sinokusebenzisa uphawu lwe-Defer, oluluphawu olunqabileyo olunqabileyo kwiJavaScript.

Awunakuze uyisebenzise, ​​kodwa ndiqinisekile ukuba awuyi kuyishiya emva kokufunda le ntshayelelo.

Owona msebenzi wayo kukuvumela iscript sicazulule lonke iphepha emva kokuba lilayishile, kunokuba licazulule ngexesha lokulayisha, elibonelela ngesantya somthwalo wephepha elipheleleyo kwizikripthi eziqulathe kuphela iJavaScript enesiganeko.

Ewe, ukuba ithegi yeSikripthi inophawu lwe-defer, nokuba ibekwe entloko, iya kuphunyezwa emva kokwahlulahlula iphepha le-HTML, elifana nokubeka i-Script ezantsi kwephepha.

Kakade ke, ukusetyenziswa kokulibaziseka nako kulinganiselwe. Ngokubanzi, amanqaku amabini kufuneka aqatshelwe:

1) Musa ukubiza umyalelo we-document.write kwibhloko yeskripthi sohlobo lwe-defer;

• Kuba i-document.write izakuvelisa iziphumo ezithe ngqo zemveliso.

2) Ungabandakanyi naziphi na izikripthi zokwenziwa ngokukhawuleza eziza kusebenzisa iinguqu zehlabathi okanye imisebenzi kwi-Defer scripts.

Yongeza uphawu lweDefer kwiscript esisetyenziswe kwiWordPress

Kwi-WordPress, sinokongeza njani ngokuzenzekelayo iimpawu ze-Defer kwizikripthi ezisetyenziswe yi-WordPress?

Singongeza le khowudi ilandelayo kumxholo wangoku wefayile 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";
};

• Le khowudi ingentla isebenza kuphela, ngokusekelwe kwiIkhowudi yeJavaScript yaziswa ngeWordPressiya kusebenza.

Ukuba usebenzisa le khowudi ingasentla, isenokungabi nanto xa uvula ulawulo lomboniso wexesha lokwenyani (Imbonakalo → Lungiselela), ngoko nceda uyisebenzise ngokufanelekileyo.

Xa ulawulo lokujonga kwangaphambili lufuneka, phawula ngale khowudi ingentla, kwaye ucime ikhowudi yezimvo emva kokuba kwenziwe ngokwezifiso.
