Ngokuqinisekileyo, masiqale ngenqaku. Ndiza kugxila kumanqaku achazwe kwisakhiwo:
Ngaba ukhe wazibuza ukuba isetyenziswa njani iJavaScript ukuvula ifayile yencoko yababini ngokucofa iqhosha? Lo ngumbuzo oqhelekileyo oza kubaphuhlisi, ngakumbi xa usenza ujongano olusebenziseka lula olufuna ukufakwa kweefayile. Kweli nqaku, siza kuvavanya isisombululo esilula kule ngxaki, esibandakanya i-HTML 'yegalelo' element, enye i-CSS, kunye nentwana yomlingo weJavaScript.
I-CORS, ngenye indlela eyaziwa ngokuba yi-Cross-Origin Resource Sharing, yi-HTTP protocol echaza indlela iifayile ezabelana ngayo phakathi kweendawo. I-CORS idlala indima ebalulekileyo kukhuseleko lwewebhu ngokulawula ukuba zeziphi izikripthi ezinokufikelela kwimithombo kwiphepha, ukuze kuthintelwe ukufikelela kwedatha okungagunyaziswanga okanye ukwaphulwa kokhuseleko olunokwenzeka. Nangona kunjalo, i-CORS ngamanye amaxesha inokubonisa imiba, ngakumbi xa izama ukulanda izixhobo ukusuka kwindawo eyahlukileyo. Xa kukho ingxaki, uya kubona impazamo ye-CORS. Ukuqonda ukuba yintoni ebangela le mpazamo kunye nendlela yokuyilungisa kunokukwenza ube ngumphuhlisi osebenzayo weJavaScript.
Ngokuqinisekileyo, nantsi ukujonga nzulu kwindlela yokufaka iFlexbox:
I-Flexbox, imfutshane kwi-Flexible Box Module, yimodeli yoyilo kwi-CSS3 ebonelela ngesisombululo esilula nesifuneka kakhulu sokuyila izakhiwo eziphendulayo eziguqukayo ngaphandle kokusebenzisa ukudada okanye ukubeka.
I-Angular Flex Layout inikeza igridi eguquguqukayo kunye nempendulo. Isebenzisa imodeli ye-flexbox ye-CSS3 yokuguquguquka okuphezulu. Ikwabonelela abaphuhlisi be-Angular nge-API eyakhiwe kakuhle ukuyila amaphepha ewebhu ngaphandle kokusebenzisa i-bootstrap okanye naziphi na ezinye izisombululo ezisekelwe kwi-CSS.
I-Angular Flex Layout sisixhobo esinamandla sokwakheka kuba inceda ukulawula ubungakanani bezinto kunye nesithuba phakathi kwabo, okwenza kube lula ukwenza ujongano lomsebenzisi ophendulayo.
Nangona oku kunokubonakala kunzima ekuqaleni, eli nqaku liza kukukhokela kwinkqubo, lichaza inyathelo ngalinye ukukunceda ukuba uliqonde ngcono. Iithegi, iikhowudi, kunye nezisombululo zonke ziya kuchazwa ngokweenkcukacha.
Ngokuqinisekileyo, nali inqaku:
Ukuqonda i-enigma yokuseta ububanzi besikrini yingxaki eqhelekileyo abadibana nayo abaphuhlisi. Nokuba wenza uyilo oluphendulayo okanye ujongana nemiba yofikelelo, kubalulekile ukuqonda ngqo ukuba ungabusebenzisa njani ububanzi besikrini ngokuchanekileyo. KwiJavaScript, kulula ukufumana ububanzi besikrini sombukeli. Into yewindow.screen ingasetyenziselwa ukufunda ububanzi beskrini. Ngoku, masingene sijule ukuze sikuchaze ngcono oku kwimihlathi elandelayo.
Kweli xesha lanamhlanje eliqhutywa yitekhnoloji, inkqubo ye-frontend kwaye ngakumbi ukusebenza kwiJavaScript ibe ngumsebenzi onzima kodwa onomdla. Ngexesha kunye nezikhokelo ezitsha, kuya kuba luncedo kwaye kuyakhawuleza ukuphuhlisa usetyenziso lwewebhu. Enye inkalo enjalo yeprogram ye-frontend kukuphuhlisa amacandelo kwisicelo. Nangona kunjalo, ngamanye amaxesha, sinqwenela ukuvelisa icandelo ngaphandle kwefayile yenkcazo (spec). Kulapho umxholo wethu ophambili uhlala khona namhlanje. Kweli nqaku, siza kuphonononga ukusombulula le ngxaki ikhethekileyo ngokufanelekileyo.
intshayelelo
Ukuba ngumphuhlisi kumaxesha anamhlanje kuthetha okungakumbi kunokwazi nje ukwenza inkqubo; ikwabonisa iqondo lobuchule bobugcisa kunye nesayensi ye-Search Engine Optimization (SEO). Oku kukwayinyani nakwindawo yedijithali yeshishini lefashoni, apho iintsingiselo kunye nezimbo zihlala ziguquka kwaye zidibanisa. Kweli nqaku, uya kuphonononga ubudlelwane obuntsonkothileyo phakathi kwenkqubo kwiJavaScript, ukubamba i-SEO, kunye nokuhambisana neshishini lefashoni elikhawulezayo.
Umba osondeleyo
Ukuqonda ihlabathi elintsonkothileyo lefashoni, ngakumbi xa kufikwa kwimiboniso yefashoni ephezulu, inokuba ngumsebenzi onzima. Ukudityaniswa kwezitayile, imibala, imbali kunye nobuhle bomntu kunokubonakala kunzima, kodwa ngobuchwephesha obuncinci umntu unokucacisa ulwimi lwelaphu kunye noyilo.
Ifashoni, ifana neelwimi zenkqubo yekhompyuter JavaScript, inentaphane yeendlela ezahlukeneyo kunye neendlela ezinokusetyenziswa ukulungisa ingxaki. Kukho izitayile ezingenakubalwa, nganye inemithetho kunye nezikhokelo zayo, ngakumbi njengamathala eencwadi ahlukeneyo okanye isakhelo esinokusebenza ngaso kwiJavaScript.
Umzekelo, isimbo se-Bohemian, esisoloko sibizwa ngokuba 'yi-boho', sisimbo esiphenjelelwe yintshukumo yenkululeko yoo-1960s kunye noo-1970. Ibandakanya izinto ezithandekayo, i-eclecticism kunye nempepho ethile, ubuhle obungenamoya. Izikimu zombala ziqhelekile emhlabeni, zineentsundu ezinzulu, eziluhlaza, kunye neetoni zejewel.
Ngokwahlukileyo, isitayile seMinimalist sicocekile, sikrwada, kwaye sigxile kumbono 'wokuncinci kungaphezulu'. Sisitayile esinokunxulunyaniswa nococeko, olusebenzayo lwekhowudi yeJavaScript engachithi imijikelo kwimisebenzi engafunekiyo.
Imiboniso yefashoni, efana nomjikelo wophuhliso lwesoftware, iyaguquka kwaye ithobela intsingiselo kunye nemigangatho. Umgaqo weenqwelo-moya liqonga labayili ukuba bangabonisi imigca yabo yamva nje kuphela, kodwa baphinde baveze ubuhle babo ngeyona ndlela iyilayo nengangxengwanga.
I-AngularJS, isakhelo seJavaScript esivulelekileyo, sisixhobo esisebenzayo esiphuhliswe nguGoogle. Injongo yalo kukwandisa izicelo ezisekelwe kwisikhangeli kunye ne-MVC (iModel View Controller) ikhono, ukwenza lula zombini uphuhliso kunye nenkqubo yokuvavanya. Olu phuhliso lwesoftware lunceda ekudaleni ii-Single Page Applications (SPA) ngendlela ecocekileyo negcinekayo.
