Iwindo re-pop-up riri [rakabviswa]. Mhando dzayo uye zvinangwa zvekusika

Zvinonyatsozivikanwa kuti mapeji eIndaneti anoshandiswa mu hypertext markup language, iyo iyo browser inoshuma mashoko ezvinyorwa pamusoro pezvimwe zvikamu zvepeji yakadaro: nzvimbo yavo nechekushandura chewindo uye mumwe nomumwe, ukuru, kurongeka. Kuti "rutsidze" peji yepaiti uye uuye nayo kune mavara akasiyana-siyana, mavara emashizha anoshandiswa anoshandiswa, anowanzotorwa kubva muhombe huru ye peji - html-code. Kushandiswa kwe html ne css kunoita kuti zvive nyore kuona pfungwa dzakaoma zvikuru dzewebhu web designer. Zvisinei, peji yakadaro, zvisinei nokuti yakave yakaisvonaka, haisi kupindirana, kureva kuti, haikwanise kutaurirana nemunhu ari kugara pamberi pekombiyuta.

Nzvimbo ipi neipi yemazuva ano yakashandiswa uchishandisa mapurogiramu akawanda emitauro, iyo JavaScript inowanikwa.

JavaScript (JS) iri chirongwa chekushandiswa chekushandura mapeji e-interactive. Pakarepo zvinodiwa kukuyeuchidza, kuti JavaScript uye Java chete - mitauro miviri yakasiyana, kuita mabasa akasiyana. Nheyo dzeJS ndezvinyorwa - mapurogiramu maduku ane zvigadziro zvemirairo yakatarwa inofanira kushandiswa panzvimbo iyi pane imwe nguva. Aya mapurogiramu anogona kuiswa zvakananga mumuviri we html-document huru ye peji kana kutorwa kubva mumiganhu yayo mune imwe faira uye akabatanidzwa nayo achishandisa chiitiko chakanaka chinoratidza nzvimbo yefaira iyi. Nekubatsirwa kwaJS, iwe unogona nyore nyore "kumutsidzira" peji yepaiti nekugadzira pop-up welcome window, kadhigiramu inoshanda kana awa, fomu yekunyora uye kutumira mameseji, nezvimwewo.

Ngatitaurire mune mamwe mashoko pamusoro pemapurogiramu ep-up akanyorwa mumutauro weJavaScript mutauro, uyo kazhinji kechikwangwani chiduku chinowanzooneka pamusoro peji main browser window apo mushumiri anoita chero manipulations (somuenzaniso, paunosangana pane rimwe shoko kana mufananidzo). Mune zvimwe zviitiko, festi yepup-up inowanikwa pachikanda chekuona pakarepo mushure mekuvhara peji yepaiti. MuJS, mitatu yemahwindo akadaro anoshandiswa:

- Chiratidzo chinoshandiswa mumatambudziko iwayo apo ruzivo rwakaratidzwa mairi runofanirwa kuve rwakavimbiswa kuendeswa kunoshanyi wepaiti. Zvimwe zviito panzvimbo iyi munyaya ino zvinogoneka chete mushure mekutora bhodhi "OK" nemushandi pachake.

- Mushumo wekududzira-firimu unoshandiswa apo zvakakosha kuve nechokwadi chokuti mushandisi anopinda pane zvimwe zvinhu asati apinda peji yewebsite.

- Iwindo rekusimbisa rinogona kushandiswa kuve nechokwadi chokuti musikana anobvumirana nechinhu. Muchiitiko ichi, zvichave zvakakosha kudhura kukosha "Ok" kana "Cancel".

Zviri nyore kunyora pop-up script. Kuti uite izvi, unofanira kunge uine ruzivo rwepakutanga rwemaJavaScript. Kuti uone kana iri kushanda yakanyorwa kana kwete, unotanga kutanga chero upi zvake weIndaneti. Somuenzaniso, script: ziso ("Hello") icharatidzwa muInternet Explorer sehwindo rine shoko rokuti "Hello" pamusoro pehwindo rayo guru. Kushandisa JS, unogona kuchinja window ye-pop-up (yakafara, kureba, nzvimbo), ita kuti irege kuonekwa mushure mekunge mushanyi ashanyira peji yesaiti, uye mushure mokunge aita zvimwe zvayo.

Kune mavara akawanda mukugadzirwa kwenzvimbo. Iko kunofanira kunzwisiswa kuti kushamwaridzana kwezvinyorwa, zvechokwadi, kunokwezva kutarisa kwayo uye kunoisa kune iyo pachayo. Zvisinei, iwe haufaniri kuve uchibatanidzwa mune zvinyorwa zvinyorwa, kunyanya, mawindo ep-up. Vanowanzogumbura vashandi vakawanda. Mazuva ano browsers inopa kubviswa kwezvinhu zvakadaro zvepaji yepaiti, zvichikubvumira kuti ubvise mawindo ekuputika nekudzivisa basa rinowirirana mumenyu yavo. Kana zvichidikanwa, unofanirwa kudzokera kumenyu uye unodzorera kukwanisa kuratidza shanduro yedhesi zvinyorwa.
