Impela, ake siqale ngesihloko. Ngizogxila emaphuzwini achazwe esakhiweni:
Wake wazibuza ukuthi isetshenziswa kanjani i-JavaScript ukuvula ingxoxo yokufaka ifayela ngokuchofoza inkinobho? Lona umbuzo ojwayelekile oza konjiniyela, ikakhulukazi uma udala izixhumanisi ezisebenziseka kalula ezidinga ukulayishwa kwamafayela. Kulesi sihloko, sizohlola isisombululo esilula sale nkinga, esibandakanya isici 'sokufaka' se-HTML, i-CSS ethile, kanye nomlingo omncane we-JavaScript.
I-CORS, eyaziwa nangokuthi Ukwabelana Ngezinsizakusebenza Kwe-Cross-Origin, iyiphrothokholi ye-HTTP ebeka ukuthi amafayela abiwa kanjani phakathi kwezizinda. I-CORS idlala indima ebalulekile ekuvikelekeni kwewebhu ngokulawula ukuthi yiziphi izikripthi ezingafinyelela izinsiza ekhasini, ukuze kuvinjelwe ukufinyelela kwedatha okungagunyaziwe noma ukwephulwa kokuphepha okungenzeka. Kodwa-ke, i-CORS kwesinye isikhathi ingaletha izinkinga, ikakhulukazi lapho izama ukulanda izinsiza kwesinye isizinda. Uma kuvela inkinga, uzobona iphutha le-CORS. Ukuqonda ukuthi yini ebangela leli phutha nokuthi lilungiswa kanjani kungakwenza ube umthuthukisi we-JavaScript osebenza kahle kakhulu.
Impela, nakhu ukubheka okujulile kokuthi ungayifaka kanjani i-Flexbox:
I-Flexbox, emfushane ye-Flexible Box Module, iyimodeli yesakhiwo ku-CSS3 ehlinzeka ngesixazululo esilula nesidingeka kakhulu sokuklama izakhiwo eziphendulayo eziguquguqukayo ngaphandle kokusebenzisa ukuntanta noma ukuma.
I-Angular Flex Layout inikeza igridi eguquguqukayo nesabelayo. Isebenzisa imodeli ye-flexbox ye-CSS3 ukuze kube nokuguquguquka okuphezulu kwesakhiwo. Iphinde inikeze abathuthukisi be-Angular nge-API ehlelwe kahle yokuklama amakhasi ewebhu ngaphandle kokusebenzisa i-bootstrap noma ezinye izixazululo ezisekelwe ku-CSS.
I-Angular Flex Layout iyithuluzi lesakhiwo elinamandla ngoba lisiza ukuphatha usayizi wezakhi kanye nesikhala phakathi kwazo, okwenza kube lula ukudala isixhumi esibonakalayo somsebenzisi esiphendulayo.
Nakuba lokhu kungase kubonakale kuyinkimbinkimbi ekuqaleni, lesi sihloko sizokuqondisa kunqubo, sichaze isinyathelo ngasinye ukuze sikusize usiqonde kangcono. Amathegi, amakhodi, nezixazululo konke kuzochazwa ngokuningiliziwe.
Impela, nasi isihloko:
Ukuqonda indida yokusetha ububanzi besikrini kuyinkinga evamile onjiniyela abahlangabezana nayo. Kungakhathaliseki ukuthi udala imiklamo esabelayo noma ubhekana nezinkinga zokufinyeleleka, kubalulekile ukuqonda ngokuqondile ukuthi ungalawula kanjani ububanzi besikrini ngendlela efanele. Ku-JavaScript, kulula ukuthola ububanzi besikrini sesibukeli. Into yewindi.isikrini ingasetshenziswa ukufunda ububanzi besikrini. Manje, ake sicwilise ukuze sikuchaze kangcono lokhu ezigabeni ezilandelayo.
Enkathini yanamuhla eqhutshwa ubuchwepheshe, ukuhlela okuphambili futhi ikakhulukazi ukusebenza ku-JavaScript sekuphenduke umsebenzi oyinselele kodwa othokozisayo. Ngokuhamba kwesikhathi nezinhlaka ezintsha, kuyasiza futhi kuyashesha ukuthuthukisa izinhlelo zokusebenza zewebhu. Isici esisodwa esinjalo sohlelo lwe-frontend ukuthuthukisa izingxenye kuhlelo lokusebenza. Nokho, ngezinye izikhathi, sifisa ukukhiqiza ingxenye ngaphandle kwefayela lokucaciswa (spec). Kulapho isihloko sethu esikhulu sihlala khona namuhla. Ngaphakathi kwalesi sihloko, sizongena ekuxazululeni le nkinga eyingqayizivele ngempumelelo.
Isingeniso
Ukuba unjiniyela ezikhathini zanamuhla kusho okungaphezu kokwazi nje ukuhlela; futhi ikhombisa izinga lokushelela kwezobuciko nesayensi ye-Search Engine Optimization (SEO). Lokhu kuphinde kubambezeleke emkhakheni wedijithali wemboni yezemfashini, lapho amathrendi nezitayela zilokhu zishintsha futhi kuhlanganiswe. Kulesi sihloko, uzohlola ubudlelwano obuyindida phakathi kwezinhlelo ze-JavaScript, ukwenza i-SEO kahle, nokuhambisana nemboni yemfashini esheshayo.
Udaba Oluseduze
Ukuqonda izwe eliyinkimbinkimbi lemfashini, ikakhulukazi uma kuziwa emibukisweni esezingeni eliphezulu eyimibukiso yemfashini, kungaba umsebenzi onzima. Ukuhlangana kwezitayela, imibala, umlando kanye nobuhle bomuntu siqu kungabonakala kungaphezu kwamandla, kodwa ngobungcweti obuncane umuntu angakwazi ukuchaza ulimi lwendwangu nokuklama.
Imfashini, ifana nezilimi zokuhlela zekhompyutha ezifana i-JavaScript, inenqwaba yezitayela nezindlela ezahlukene ezingasetshenziswa ukubhekana nenkinga. Kunezitayela ezingenakubalwa, ngasinye sinemithetho nemihlahlandlela yaso, njengemitapo yolwazi ehlukene noma izinhlaka umuntu angase asebenze ngazo ku-JavaScript.
Isibonelo, isitayela se-Bohemian, esivame ukubizwa ngokuthi 'i-boho', isitayela esagqugquzelwa iminyaka yo-1960 kanye no-1970 ukunyakaza kwenkululeko. Ihlanganisa izici ze-whimsy, i-eclecticism kanye nobuhle obuthile obuhelezayo, obunomoya wamahhala. Izikimu zemibala ngokuvamile zinomhlaba, ziqukethe okunsundu okujulile, okuluhlaza okotshani, namathoni ayigugu.
Ngokuphambene, isitayela se-Minimalist sihlanzekile, sihlanzekile, futhi sigxile embonweni wokuthi 'okuncane kuningi'. Kuyisitayela esingafaniswa nocezu oluhlanzekile, olusebenzayo lwekhodi ye-JavaScript engamoshi imijikelezo ekusebenzeni okungadingekile.
Imibukiso yemfashini, njengemijikelezo yokuthuthukisa isofthiwe, iyashintshashintsha futhi ihambisana namathrendi namazinga ashintshashintshayo. Umzila wezindiza uyinkundla yokuthi abaklami bangagcini nje ngokubonisa imigqa yabo yakamuva, kodwa futhi baveze ubuhle babo ngendlela enobuhlakani kakhulu nengaxutshiwe.
I-AngularJS, uhlaka lomthombo ovulekile we-JavaScript, iyithuluzi elisebenzayo elakhiwe i-Google. Inhloso yakhona ukukhulisa izinhlelo zokusebenza ezisuselwe kusiphequluli ngamandla we-MVC (Model View Controller), okwenza kube lula kokubili ukuthuthukiswa kanye nenqubo yokuhlola. Lokhu kuthuthukiswa kwesofthiwe kusiza ekudaleni Izicelo Zekhasi Elilodwa (SPA) ngendlela ehlanzekile nelondolozekayo.
