Ngokutsho kweW3C, impawu zobunikazi kwi-HTML yile:
ikhonkco ekhethekileyo yento
Le ngcaciso elula yenkalo enamandla kakhulu. Isalathisi se-ID singenza amanyathelo amaninzi kumakhasi ewebhu:
- Umkhethi wefayile yesitayela - Lo ngumsebenzi uninzi lwabantu basebenzisa isalathisi se-ID. Ngenxa yokuba zihlukile, unokuqiniseka ukuba uya kubhala into enye kwiWebhu yekhasi lakho xa usitayela usebenzisa isakhiwo se-ID. Ingcambu ekusebenziseni i-ID ekujoliswe kuyo kubonisa ukuba inqanaba eliphezulu kakhulu lobume, oko kungenza kube ngumngeni kakhulu ukuba ufuna ukugqithisa isitadi ngesizathu esithile emva kweefayile. Ngenxa yoko, iikhowudi zeWebhu zangoku zixhomekeke ekusebenziseni iiklasi kunye nabakhethi beklasi endaweni yee-ID kunye nabakhethi be-ID ukwenzela injongo yokucwangcisa jikelele.
- Iinqwelo ezibizwa ngokuba zidibanisa kwi-Web browsers zivumela ukuba ujolise kwiindawo ezichanekileyo kumaphepha akho eWebhu ngokukhomba i-ID ekupheleni kwe-URL. Uvele wongeze i-id ekupheleni kwe-URL yekhasi, elandelwe ngumqondiso wepounds (#). Unokudibanisa nalawa mahange ngekhasi ngokwayo ngokufaka uphawu lwepound (#) kunye negama le-ID kwi-attribute ye-href yento. Ngokomzekelo, ukuba unesahlulo kunye ne-ID yothintana naye, unokudibanisa nayo kwiphepha ngale ndlela:
Le yilekisi yekhonkco - Isalathiso seempendulo-Ukuba ubhala nayiphi na imisebenzi yeJavascript, uya kufuna ukusebenzisa impawu ye-ID ukwenzela ukuba wenze utshintsho kwindawo echanekileyo kwiphepha ngeempendulo zakho.
- Olunye usebenze - I-id ikuvumela ukuba usebenzise amaxwebhu akho eWebhu nangayiphi indlela oyifunayo. Ngokomzekelo, unokukhipha i-HTML kwisiseko sedata, kwaye uphawu lwe-ID luchonga amasimi.
Imigaqo yokusebenzisa i-ID ye-ID
Kukho imigaqo embalwa omele uyilandele ukuba ube nomqulu ochanekileyo osebenzisa isalathisi se-id naphina kwidokhumenti:
- Izazisi kufuneka ziqale ngeleta (az okanye AZ)
- Zonke iilwimi ezilandelelanayo zingabhala iileta, iinombolo (0-9), i-hyphens (-), igxininisa (_), iikholoni (:), kunye namaxesha (.).
- I-ID nganye kufuneka ibe yodwa kwixwebhu. Ngoba?
Ukusebenzisa i-ID ye-ID
Emva kokuba ufumene into ekhethekileyo kwiWebhsayithi yakho, ungasebenzisa iifayile zesitayela kwisitayela nje kuphela.
Qhagamshelana nathi
Kukho okubhaliweyo kwimixholo apha
div # kwicandelo loqhagamshelwano {imvelaphi: # 0cf;}
- okanye nje
# kwicandelo loqhagamshelwano {imvelaphi: # 0cf;}
Eminye yababini abakhethi bayeza kusebenza. Iyokuqala (i-div # ye-section-contact) iya kujolisa ukwahlula nge-ID yempawu ye "candelo-xhumana". Inxalenye yesibini (i-# yecandelo loqhagamshelwano) iya kujolisa i-element kunye ne-ID ye "candelo-nxu lumene", ayikwazi ukuba into ekhangeleyo yiyohlulo. Isiphumo sokuphela kwesimboli siza kufana.
Unokudibanisa naloo nto ethile ngaphandle kokungena nayiphi na ithegi:
Qhagamshelana nolwazi lokuqhagamshelana
Ukubhekisela kwimihlathi kwiempendulo zakho kunye ne "GetElementById" indlela yeJavaScript:
uxwebhu.getElementById ("icandelo loqhagamshelwano")
Iimpawu zobunikazi zisasebenziseka kakhulu kwi-HTML, nangona abakhethi beklasi baye bathatha indawo yabo kwiinjongo eziqhelekileyo zokucwangcisa. Ikhono lokusebenzisa impawu ze-ID njengentambo yezitayela, ngelixa zisebenzise njengama-anchors kwiziqulatho okanye iithagethi zeempendulo, kuthetha ukuba basenendawo ebalulekileyo kwi-Web design namhlanje.
