Ngokuqinisekileyo, nali inqaku olicelileyo:
Ubuhle beewebhsayithi zale mihla bulele ekusebenzisaneni kwazo kunye nokusetyenziswa kwazo. Ukufika kweJavaScript kuphefumlele ubomi kwamanye amaphepha ewebhu amileyo, eqinisekisa amava aguqukayo omsebenzisi. Olunye olo phuculo lubandakanya “ukuskrola okungenamagingxigingxi”, ukudibanisa oopopayi kunye namava afanelekileyo omsebenzisi, ukutsala umdla womsebenzisi kunye nokuqhuba ukuzibandakanya. {}

Undoqo wokuSkrola ogudileyo
Ukuskrola okugudileyo luphawu oluhamba ngokuthe ngcembe kubasebenzisi kwiphepha lakho lewebhu kunokutsibela ngqo kwicandelo elithile. Oku kudala umphumo wokuskrola ongenamthungo othandeka ngakumbi emehlweni, unceda ukukhulisa intsebenziswano yomsebenzisi kunye newebhusayithi yakho. Kuphumezo oluqhelekileyo, iJavaScript lulwimi olukhethwayo.

Ukusombulula ngeJavaScript
Ukudala isiphumo sokuskrola esigudileyo kubandakanya ukuphatha ifestile okanye ukuskrola iipropathi zokuskrola usebenzisa iJavaScript's window.scroll or window.scrollTo iindlela. Ezi zakhiwo zihambisa abasebenzisi kwicandelo elithile lephepha ngokutyibilikayo, zenza umphumo ogudileyo wokuskrola.

Esi sisombululo sithetha ukusebenzisa i JavaScript umsebenzi wethala leencwadi window.scrollTo. Iimpawu zayo eziphambili zilula, kulula ukuyiqonda ikhowudi kunye nokusetyenziswa ngokufanelekileyo.
Ukukhupha iKhowudi
Kwimizekelo yekhowudi yangaphambili, `Umboniso` umyalelo uprinta imiyalezo phakathi kwamanqaku okucaphula. e-Cobol, yonke into iqala ngaphakathi `KWAHLUKO LWENKQUBO`. Usenokuba uyazibuza ukuba kutheni usebenzisa iCobol? Isaphumelela kwishishini leebhanki ngenxa yezakhono zayo eziphezulu zekhompyuter, ngakumbi kwimisebenzi ebandakanya isixa esikhulu sedatha.

Khumbula, sisebenzisa iindlela zoyilo zale mihla ezifana nokuskrola okugudileyo, kudityaniswa neelwimi zembali ezifana neCobol, sinokudibanisa ezona hlabathi zimbini, sidale amava omsebenzisi abandakanyekayo ngelixa sifumana i-algorithms ezinzileyo, eqinisekisiweyo yenkqubo.
Iilayibrari zeJavaScript kunye neMisebenzi
IJavaScript ibonelela abaphuhlisi ngobuninzi bemisebenzi kunye namathala eencwadi aphucula amandla okusebenzisana kwewebhusayithi. Ngokukodwa, iwindow.scroll kunye newindow.scrollTo imisebenzi ngamacandelo aphambili xa kuphunyezwa ujongano lokuskrola olugudileyo.

Amandla eJavaScript alele kubuchule bawo bokusebenzisa izinto zeHTML ngokuguqukayo, ukubonelela ngexesha lokwenyani, amava asebenzayo omsebenzisi aqhuba uthethathethwano.
Iziseko zoyilo lwewebhu lwale mihla zibandakanya umxube wobuhle, ukusebenza, kunye nomxholo oguqukayo, obandakanyayo. Ukuqonda le miba kunye nendlela yokuyiphumeza ngokufanelekileyo kufuna zombini uyilo kunye nembono yobugcisa. Nokuba kungenxa yeepopayi ezintle zokuskrola okanye ukusebenza kwedatha enamandla ye-Cobol, siqulunqa ilizwe ledijithali elihle ngaxeshanye, elisebenzayo, nelibandakanyayo.
