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.
i-JavaScript
Ngemva kokudalwa kwewebhu nge-HTML kanye nesakhiwo sayo nge-CSS, i-JavaScript isiwulimi esingaxhumana ngalo nomsebenzisi esipheqululini.
Kodwa uma lokhu kungezwakali njengokukhulu kuwe, umsebenzi weJavaScript wedlulele, waba ulimi lwabo bobabili abathuthukisi be-FrontEnd kanye ne-BackEnd.
Izinhlaka eziningi zidaliwe ngokusekelwe ku-JavaScripts.
Singathuthukisa noma yini kuhlanganise ne-AppWeb edumile.
Ngaphandle kokungabaza, i-JavaScript iwulimi wonke umklami okufanele alwazi kahle namuhla.
Kulesi sigaba sikusiza ngokungabaza okuvamile kanye nezinkinga zansuku zonke.
Kuxazululiwe: setha ububanzi besikrini
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.
Kuxazululiwe: kugijima kanjani
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.
Ukuqonda Izitayela Zemfashini
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.
Ukuqonda Amathrendi we-Runway
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.

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
Kuxazululiwe: ukukhiqiza ingxenye nge-angular ngaphandle kwefayela elicacisiwe
Emhlabeni we-Angular, uhlaka oluhlonishwayo ngenxa yokuguquguquka, ukukhiqiza kanye nokukala, ngezinye izikhathi sihlangabezana nemisebenzi engalandeli inkambiso evamile. Umsebenzi owodwa onjalo uhilela ukudala ingxenye ngaphandle kokukhiqiza ifayela elicacisiwe (noma elithi 'spec'). Ifayela elicacisiwe yifayela lokuhlola elihlotshaniswa nengxenye ye-Angular.
Nakuba inqubo ngokuvamile iqondile, ngokuvamile ingavusa umbuzo: senza kanjani mayelana nokukhiqiza ingxenye nge-Angular ngaphandle kwefayela elicacisiwe? Asiluqale ndawonye lolu hambo futhi sithole.
Ixazululiwe: angularjs cdn
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.
Kuxazululiwe: ikilasi lengeza le-angular yendabuko
I-Angular iwuhlaka olungaphambili olwakhiwe i-Google lokudala izinhlelo zokusebenza zewebhu eziguqukayo, zesimanjemanje. Esinye sezici ezibalulekile ezinikeza ukuguquguquka namandla ku-Angular ukusebenzisana ne-HTML DOM (Imodeli Yento Yedokhumenti). Ingxenye ebalulekile yalokhu kuhlanganyela ihlanganisa ukungeza noma ukususa amakilasi ngokushintshashintshayo ezintweni ze-HTML. Nge-Angular, i-NativeElement iyangena ukuze isebenzise lo msebenzi. I-NativeElement ihlanganisa i-API yesiphequluli somdabu evumela ukukhohliswa kwezinto ze-HTML. Kulesi sihloko, sizocubungula ukusetshenziswa kwe-NativeElement ekwengezeni iklasi entweni ye-HTML.
Kuxazululiwe: inkambu yokufaka yefomu ifundeka kuphela
Izinkambu zokufaka zefomu, ingxenye etholakala yonke indawo ekuthuthukisweni kwewebhu, inezakhiwo eziningi. Enye yalezi yisibaluli 'sokufunda kuphela' esisetha inkambu yefomu njengeyokufunda kuphela. Lokhu kuwusizo ikakhulukazi ezimeni lapho ufisa ukubonisa idatha okungadingeki ukuthi ihlelwe umsebenzisi. Inikeza onjiniyela ukulawula okwengeziwe phezu kwezakhi zefomu emakhasini ewebhu, ukuthuthukisa umuzwa wokusebenzelana wabasebenzisi. Lesi sihloko siwukuhlaziya okujulile kanye nomhlahlandlela osebenzayo wokuthi ungasebenzisa kanjani isibaluli "sokufunda kuphela" ku-JavaScript ngempumelelo.
Kuxazululiwe: engeza umzila enkinobho
Impela! Nansi indatshana oyicelile:
Umhlaba wokuthuthukiswa kwewebhu uwulwandle olukhulu lwamathuba futhi ngokufika kweJavaScript, lolu lwandle seluthakase kakhulu. Ulimi lwe-JavaScript lusivumela ukuthi senze inqwaba yemisebenzi ehlanganisa nokwengeza imizila enkinobho ezinhlelweni zethu zokusebenza. Kulesi sihloko, sizohlola lesi sici se-JavaScript, ikakhulukazi, indlela yokwengeza umzila enkinobho, ngomhlahlandlela wesinyathelo nesinyathelo.
