Protocol: // igama lesizinda / indlela wefayela
Isibonelo ikheli kusandile e Melika enjini: https://aol.com - ngokuphelele, ngoba iqukethe igama lesizinda Play.
hyperlink Ingabe Ohulumeni Banalo Lonke asetshenziswa ukuya emakhasini amanye amasayithi noma ukufinyelela imithombo etholakala kwenye iseva. Inguquko wenziwa ngokusebenzisa lasesizindeni se-intanethi. Izivumelwano - lokhu akulona isihloko lesi sihloko, kodwa njengoba iqhaza ukudalwa hyperlink, kumelwe okungenani kafushane kubo:
- http kanye https - okuvame kakhulu; ngabo ukuze ushintshe phakathi amakhasi ewebhu kumasayithi wakwa ezahlukene;
- FTP - uphrothokholi nokulayisha amafayela kwiseva noma okulandwayo umsebenzisi ukusuka kusayithi;

hyperlink isihlobo
Nge isihlobo ekhuluma, ukusetshenziswa hyperlink le-HTML esetshenziselwa ushintsho ekuphileni futhi aliholeli ukudlula lokho. Uma ikhasi le-likhulu eyehlayo scrollbar mpo, ngezinye izikhathi eside kakhulu, ezifana kusichazamazwi, kulula kakhulu futhi kuyafaneleka ukusebenzisa izixhumanisi isihlobo sifinyelele uhlamvu olufunayo.
Ukudala isichazamazwi inthanethi, Unicode ekuqaleni ikhasi has zamagama, kuthi uma hhayi ukusetshenziswa link, umsebenzisi obekungaba isikhathi eside kakhulu ukuze ujike isondo igundane ukuya incwadi "Mina".
Ukuze udale isixhumanisi isihlobo usebenzisa ithegi igama lemfanelo :
lapho ya ngokuthi ihange, kuyilapho Emuva incwadi mina - ihange uya khona. Ukuze isibonisi efanele amahange kunconywa ukusebenzisa izinhlamvu nezinombolo, ngakho ungabhali "Mina", nakuba kwakuyoba kuyaqondakala.
Manje njengoba aphuma zamagama ekuqaleni ikhasi incwadi "Mina", kubalulekile ukwenza isikhonkwane ihange le-HTML-mbhalo, oqala ngohlamvu "Mina":
phambi ihange imele uphawu lwenombolo, ngaphandle kwalokho kwathatha incwadi ngeke zisebenze.
Isihlobo ekhuluma lapho ekwakheni iwebhusayithi
Kalula futhi algorithm ezivamile ngokudala indawo software:
- Dala ifolda kukhompyutha yakho bese indawo yayo endaweni yokukhuleka ukuze kube lula ukufinyelela okusheshayo;

- ukudalwa ikhasi lewebhu yesibili (index.html / page2);
- Dala ifolda bese uyibeka ku amafayela image;
- Dala ifolda bese uyibeka nezinye izinto (amafayela thwebula, isibonelo);
- ukugcwaliswa okuqukethwe indawo;

| _top | usebenzisa ozimele khansela kubo bonke futhi ivula ikhasi lamanje isiphequluli iwindi |
I-syntax sokusebenzisa izimfanelo ukukhomba:
Ikhaya "Google" izovula ewindini elisha.
Qaphela: ukuvula ikhasi ithebhu entsha, akukho ukubaluleka yalesi sibaluli, kanti lihlelwe ngumsebenzisi izilungiselelo isiphequluli.
Umbala izixhumanisi

Ukukhokhela izingcingo ezenziwe kwamaloli nezimoto uma zidlula. Ngakho-ke, uma-Inthanethi akanamkhawulo, izingcingo mahhala.
Yokuziphatha ukudala izixhumanisi
Ngokubeka indawo kuyi-Internet, wewebhusayithi kufanele wazi ukuthi iziphi izinhlobo kukhona izixhumanisi ku-HTML, hhayi kuphela ilungelo lokusebenzisa kubo efanele, kodwa futhi banamathele iinjamiso ezilandelako:
- I oxhumano kumelwe kubonakale kalula, sihluke umbhalo kwalo. Umsebenzisi kumele azi ukuthi it is - isixhumanisi.
- Umsebenzisi kumele kube sobala lapho uzothola ngokuchofoza ilinki. Ukuze wenze lokhu, kungcono ukusebenzisa ngemfanelo isihloko kabanzi, okuyinto ngamafuphi ichaza ikhasi ukuguqulwa. Syntax kwesicelo imfanelo kuyinto:
- Umsebenzisi kumele bathole ulwazi olunembile mayelana nefayela ezizolandwa uma uchofoze isixhumanisi.
Uma akulona ikhasi olulindelekile noma ukulanda ifayela okungalungile, umsebenzisi 99% of the ngokushesha ukushiya indawo futhi ungalokothi kuso akehlelanga esikhathini esizayo.
Anti-seo ukudala izixhumanisi
Ngaphezu ohlangothini lwezobuchwepheshe umbuzo kanjani ukufaka isixhumanisi ku-HTML, kufanele egqanyisiwe ingcenye nangokokuziphatha. Kukhona amawebhusayithi amaningi elidingekayo abasebenzisi isofthiwe yakho yezokuvikela (Antivirus), noma ngisho isimo ivinjiwe. Lawa amasayithi adaliwe ku ongcolileyo program web isandla.
Omunye namaqhinga lapho they resort - kuyinto ukufaka "esingabonakali" oxhumano ekhasini leWeb. Imikhonyovu ukwazi indlela ukudala oxhumano e-HTML, bese usebenzisa imfanelo kugcizelelani ukuze ususe izixhumanisi bese babela ke umbala indaba elizungezile ukuze umsebenzisi isilinganiso akaboni wakhe.

Uma umsebenzisi kunesithembiso isikhombisi isixhumanisi engabonakali, uthola emakhasini wokukhangisa kwamanye amasayithi. Noma nakakhulu, lapho kukhona isixhumanisi engabonakali ifayela kukhompyutha yakhe bese iyaqala futhi sifakwe isofthiwe ezingadingeki. Ngokuvamile, igciwane ukuthi ushintshe isiphequluli kwekhasi eliyisiqalo, udoti disk hard nezinye izinhlelo mass.
Ngokushesha izingosi ezinjalo ukuwela "uhlu black" database igciwane, ukuphepha kanye imvelo abasebenzisi Inthanethi. amasayithi enjalo ayihlali isikhathi eside, futhi kufanele bashintsha amagama abo ukuze uthuthe bangaphezi ku-intanethi, ukushintsha umhlinzeki aphethe.
