Ingxaki ephambili ngeGot to URL kukuba ayisebenzi njengoko ipapashiwe. Iwebhusayithi ithembisa abasebenzisi ukuba banokufikelela ngokulula kwindawo yangoku yesikhangeli sewebhu ngokufaka idilesi kwibar yedilesi, kodwa oku akunjalo. Endaweni yoko, abasebenzisi bathunyelwa kwiphepha elibacela ukuba bafake ulwazi lwabo lokungena ukuze bafikelele kwiakhawunti yabo. Oku kukuphazamiseka okukhulu kubasebenzisi abazama ukufikelela kumaphepha ewebhu okanye ukukhangela ulwazi kwi-intanethi.

Lo mgca wekhowudi uza kuqondisa kwakhona ifestile yangoku kwiphepha lasekhaya likaGoogle.
_sub_
KwiJavaScript, i-subroutine yibhloko yekhowudi engabizwa kwenye ibhloko yekhowudi.
ngokwakho ezinye iingxoxo
Kukho iindlela ezimbalwa ezahlukeneyo zokwenza iingxoxo malunga nawe kunye nezinye kwiJavaScript.
Indlela yokuqala kukusebenzisa igama elingundoqo elithi "self" elilandelwa ligama okanye inkcazo. Umzekelo, i-self.name iyakubuyisela ixabiso lepropati yegama kwinto yangoku.
Indlela yesibini kukusebenzisa igama elingundoqo elithi "enye" lilandelwa libinzana. Umzekelo, elinye.igama lingabuyisela ixabiso lepropati yegama kwinto engeyiyo into yangoku.
Iimeko zeKlasi
KwiJavaScript, iiklasi ziyimizekelo yohlobo oluthile. Zifana neenguqu ezinokuthi zibambe idatha, kodwa zineempawu ezizodwa.
Okokuqala, iklasi ingaba neepropati ezithe ngqo kwiklasi ngokwayo. Umzekelo, iklasi inokuba nepropathi ebizwa ngokuba “yigama” eligcina igama leklasi.
Okwesibini, iiklasi zinokuba neendlela. Indlela ifana nomsebenzi, kodwa iyeyeklasi endaweni yokuba incanyathiselwe kumzekelo ngamnye weklasi. Iindlela zingasetyenziswa ukwenza izinto ezinjengokudala iimeko ezintsha zeklasi okanye ukufikelela kumalungu eklasi ngaphandle kwendlela ngokwayo.
Ekugqibeleni, iiklasi zinokuba neepropati kunye neendlela ezabelwana ngazo zonke iimeko zeklasi. Oku kubizwa ngokuba "yipropathi yomzekelo." Ipropathi yeprototype ifana noguquko kuba ibamba idatha ekwabelwana ngayo ngazo zonke iimeko zeklasi. Nangona kunjalo, ngokungafaniyo nezinto eziguquguqukayo, ezinokubamba naluphi na uhlobo lwedatha, iprototype yepropathi ihlala ibamba ireferensi yento. Oku kuthetha ukuba xa usenza umzekelo weklasi usebenzisa entsha (), ufumana ireferensi yento ekhomba umzekelo weNgcaciso yento (kunokuba nje into endala ecacileyo). Ungafikelela kumalungu ale nto usebenzisa ubhalo lwamachaphaza (njengoko: Class.prototype).
Indlela yomlingo
Akukho mpendulo iqinisekileyo kulo mbuzo. Abanye abantu bakhetha ukusebenzisa iilayibrari zomthonyama zeJavaScript ezinje ngejQuery, ngelixa abanye benokukhetha ukusebenzisa iindlela "zesintu" zokucwangcisa ezinje ngeelophu kunye neengxelo ezinemiqathango. Ekugqibeleni, oko kusebenza kakuhle kumntu othile kuxhomekeke kwizinto abazithandayo kunye namava.
