Inkinga enkulu nge-Got to URL ukuthi ayisebenzi njengoba ikhangisiwe. Iwebhusayithi ithembisa abasebenzisi ukuthi bangakwazi ukufinyelela kalula indawo yamanje yesiphequluli sabo ngokufaka ikheli kubha yamakheli, kodwa akunjalo. Kunalokho, abasebenzisi baqondiswa kabusha ekhasini elibacela ukuthi bafake imininingwane yabo yokungena ukuze bafinyelele i-akhawunti yabo. Lokhu kuphazamisa okukhulu kubasebenzisi abazama ukufinyelela amakhasi ewebhu noma ukusesha ulwazi ku-inthanethi.

Lo mugqa wekhodi uzoqondisa kabusha iwindi lamanje ekhasini lasekhaya le-Google.
_sub_
Ku-JavaScript, i-subroutine iyibhulokhi yekhodi engabizwa kwenye ibhulokhi yekhodi.
ngokwakho ezinye izingxabano
Kunezindlela ezimbalwa ezihlukile zokwenza izimpikiswano mayelana nawe kanye nokunye ku-JavaScript.
Indlela yokuqala iwukusebenzisa igama elingukhiye elithi “self” elilandelwa yigama noma isisho. Isibonelo, i-self.name izobuyisela inani lempahla yegama entweni yamanje.
Indlela yesibili iwukusebenzisa igama elingukhiye elithi “okunye” kulandelwe isisho. Isibonelo, enye.name izobuyisela inani lesakhiwo segama entweni okungeyona into yamanje.
Izimo zekilasi
Ku-JavaScript, amakilasi ayizibonelo zohlobo oluthile. Ziyafana neziguquguqukayo ngoba zingabamba idatha, kodwa zinezici ezithile ezikhethekile.
Okokuqala, ikilasi lingaba nezakhiwo eziqondene nekilasi ngokwalo. Isibonelo, ikilasi lingase libe nendawo ebizwa ngokuthi “igama” eliphethe igama lekilasi.
Okwesibili, amakilasi angaba nezindlela. Indlela ifana nomsebenzi, kodwa ingeyekilasi esikhundleni sokunamathiselwa esimweni ngasinye sekilasi. Izindlela zingasetshenziswa ukwenza izinto ezifana nokudala izimo ezintsha zekilasi noma ukufinyelela amalungu ekilasi ngaphandle kwendlela ngokwayo.
Okokugcina, amakilasi angaba nezakhiwo nezindlela ezabiwa yizo zonke izimo zekilasi. Lokhu kubizwa ngokuthi "iprototype property." Isici se-prototype sifana nokuhluka ngoba sibamba idatha eyabiwa yizo zonke izimo zekilasi. Kodwa-ke, ngokungafani nokuhluka, okungabamba noma yiluphi uhlobo lwedatha, isici se-prototype sihlala siphethe ireferensi yento. Lokhu kusho ukuthi uma udala isibonelo sekilasi usebenzisa okusha(), uthola inkomba yento ekhomba isenzakalo sento Yekilasi (kunokuba nje into endala engenalutho). Ungakwazi ke ukufinyelela amalungu ale nto usebenzisa ichashazi notation (njengalokhu: Class.prototype).
Indlela yomlingo
Ayikho impendulo eqondile yalo mbuzo. Abanye abantu bancamela ukusetshenziswa kwemitapo yolwazi ye-JavaScript efana ne-jQuery, kanti abanye bangase bancamele ukusebenzisa izindlela eziningi zokuhlela “ezivamile” njengamaluphu nezitatimende ezinemibandela. Ekugcineni, lokho okusebenza kangcono kumuntu othile kuncike kulokho akuthandayo kanye nolwazi lwakhe.
