A iwindi pop-up in the [isuswe]. imibono yakhe kanye umgomo

Kuyaziwa ukuthi emakhasini izingosi ze-Internet enziwe ulimi lwemibhalo yewebhu ngawo isiphequluli ixhumana ulwazi oluyisisekelo mayelana izakhi abamelwe bekhasi ezinjalo indawo yabo isihlobo ukuba kwefasitela lesiphequluli, bahloniphane nabo bodvwana, ubukhulu oda. Ngoba "imvuselelo" isayithi alilethe umbono ezimibalabala isebenzisa Cascading Style Sheets zithathwa phandle, njengoba umthetho, ngaphandle umzimba omkhulu ikhasi - html-ikhodi. Ukusetshenziswa html futhi CSS ikuvumela ukuba uqaphele newukuhlakanipha kakhulu imibono web umklami. Nokho, ikhasi enjalo, kungakhathaliseki ukuthi ezimibalabala kunjalo, ayisebenzi, okungukuthi, alikwazi ukuxhumana umsebenzisi ehlezi phambi qapha ikhompyutha.

Noma iyiphi indawo yesimanje wadala ngokusebenzisa izilimi izinhlelo eziningi, esikhundleni sakhe phakathi kwabo kungokwalabo i-JavaScript.

I-JavaScript (JS) - ulimi lokwakha izinhlelo esetshenziswa ukudala amakhasi ewebhu interactive. Ngokushesha kufanele wakhumbula ukuthi i-JavaScript kanye Java - Ulimi ezimbili ezihlukene ukuthi imisebenzi ehlukene. JS isisekelo kuze izikripthi - izinhlelo ezincane eziqukethe iqoqo imiyalo eqondile yokuba kwenziwe esakhiweni nganoma isiphi isikhathi. Lezi zinhlelo zingafakwa ngqo emzimbeni ekhasini eliyinhloko html-mbhalo noma yakhipha angaphezu efayelini ehlukile futhi ukuxhuma kuyo c usebenzisa imfanelo ekhethekile, okubonisa indawo ifayela. Nge JS kalula "avuselele" ikhasi isayithi, ukudala-pop-up screen wamukelekile, ikhalenda wamanje noma iwashi, ifomu lokubhala ukuthumela umbhalo, njll

Sizobe ukukhuluma okuningi mayelana nezikhangiso pop-up, abhalwe JavaScript kanye okuyizinto isikwele ngokuvamile encane okuyinto kuphakama ngokuzenzakalelayo phezu isiphequluli kuwindo uma umsebenzisi bophezela phi zokukhwabanisa (isibonelo, uma uhamba phezu izwi letsite, isithombe). Kwezinye izimo, iwindi pop-up kuvela esibukweni ngokushesha emva ikhasi ukuvulwa isayithi. I JS isetshenziswa ezintathu izinhlobo zalezi amawindi:

- Isignali isetshenziswa Ezimweni lapho yonke imininingwane kufanele yibhange lidluliselwe isivakashi indawo. Isinyathelo esithuthukile esayithini Kulezo zimo kungenzeka kuphela ngemuva ngokucindezela inkinobho "OK", umsebenzisi ngokwakhe.

- A ngokushesha pop-up isetshenziswa uma ufuna ukuqinisekisa ukuthi umsebenzisi ngaphambi kokungena ikhasi, owethulwa idatha ethile.

- A iwindi isiqinisekiso singasebenza nasekunakekelweni umsebenzisi avume ukwenza noma yini. Kulokhu, uzodinga ukuba uchofoze "KULUNGILE" Inani noma "Khansela".

Bhala iskripthi-pop-up window nje ngokwanele. Ukuze wenze lokhu, kumele ube nolwazi oluyisisekelo-JavaScript. Ukuze uhlole imisebenti lebhalwako noma cha, kudingeka ukusebenzisa isiphi isiphequluli Inthanethi. Ngokwesibonelo, iskripthi: isexwayiso ( «Sawubona") izoboniswa isiphequluli Internet Explorer ewindini ethi "Sawubona" phezulu efasiteleni zako ezisemqoka. Lapho JS ukusiza ungakwazi ukushintsha Kwiwindi (ububanzi, ukuphakama, indawo), qiniseka ukuthi aliveli ngokushesha ngemva izivakashi zahamba ikhasi, futhi ngemva kokuba enziwe wakhe ezinye izinto.

Ekuthuthukiseni amasayithi kufanele bacabangele eziningi umehluko wemisindo nemiqondo yamagama. Kuyaqondakala ukuthi izinsiza inthanethi Yiqiniso, ikhanga izivakashi zayo kanye inikeza kona. Kodwa kungafanele futhi wathumba ngokubhala imibhalo, ikakhulukazi, izigelekeqe. Abasebenzisi abaningi bathi ezivame ukukucasula. iziphequluli Modern ahlinzeke uvimba izakhi ezifana amakhasi kusayithi yakho, ukuvumela ukuba asuse izigelekeqe ngokuvala option ezifanele kumamenyu zabo. Uma kudingekile, udinga ukufaka kabusha imenyu bese ukubuyisela ikhono ukubonisa idatha by scripts lesiphequluli.
