A zenera Pop-mmwamba mu [kuchotsedwa]. maganizo ake ndi cholinga cha

Amadziwika kuti tsamba la pa Intaneti analengedwa pa chinenero hypertext chizindikiro patsambali amene osatsegula amalankhulira zokhuza zinthu constituent tsamba chotero malo awo wachibale osatsegula zenera, ndi mzake, kukula kwa dongosolo la. Pakuti "chitsitsimutso" malo ndi kulowa view zokongola amagwiritsa cascading kalembedwe mapepala atengedwa, monga ulamuliro, kunja kwa thupi waukulu tsamba - HTML-code. Ntchito HTML ndi css limakupatsani kuzindikira mwaluso kwambiri maganizo ukonde mlengi. Komabe, tsamba chotero, ziribe kanthu momwe zokongola ndi, si zokambirana, Izi zitanthauza kulankhula ndi wosuta atakhala pamaso pa polojekiti kompyuta.

malo ano analengedwa ntchito zinenero angapo mapulogalamu, malo ake pakati pawo limabweretsa JavaScript.

JavaScript (JS) - chinenero mapulogalamu ntchito kulenga masamba zokambirana intaneti. Mwakucimbidza ayenera kukumbukira kuti JavaScript ndi Java - chinenero awiri osiyana kuti ntchito zosiyanasiyana. JS maziko mpaka zolembedwa - mapulogalamu yaing'ono kuti muli mndandanda wa malamulo kuti zizichitidwa pa malo pa nthawi iliyonse. Pulogalamu imeneyi adzaikidwa mwachindunji mu thupi la waukulu tsamba HTML-chikalata kapena munaupereka kupitirira mu file osiyana ndi kulumikiza izo m'ma ntchito lingaliro wapadera, kusonyeza malo wapamwamba. Ndi JS mosavuta "kutsitsimutsa" tsamba malo, kupanga Pop-mmwamba olandiridwa nsalu yotchinga, kalendala panopa kapena koloko, mawonekedwe kuti kulemba ndi kutumiza malemba, etc.

Ife kulankhula za malonda Pop-mmwamba, zinalembedwa JavaScript ndi amene nthawi zambiri yaing'ono rectangle lomwe likutuluka basi pamwamba pa waukulu osatsegula zenera pamene wosuta kuchita mpheto iliyonse (mwachitsanzo, pamene inu fungatirani pamwamba pa mawu enieni, chithunzi). Mu zina, Pop-zenera limapezeka pa zenera yomweyo pambuyo kutsegula tsamba malo. The JS ntchito mitundu itatu ya mawindo awa:

- mbendera ya ntchito pa nthawi imene onse mudziwe ayenera kungakupatseni ankasonyeza kuti malo mlendo. kanthu Komanso pa malo mu Zikatero n'chotheka pambuyo kukanikiza "Chabwino" batani, wosuta yekha.

- A Pop-mmwamba mwamsanga ntchito pamene mukufuna onetsetsani kuti wosuta asanalowe tsambali, anayambitsa deta zina.

- A zenera chitsimikiziro angagwiritsidwe ntchito kwa wogwiritsa wa anavomera chilichonse. Pankhaniyi, iye ayenera dinani "Chabwino" mtengo kapena "Kuletsa".

Lembani script Pop-zenera zokwanira basi. Kuti tichite zimenezi, muyenera kukhala Kudziŵako za JavaScript. Pofuna kuchepetsa ntchito zolembedwa kapena ayi, muyenera kuthamanga osatsegula aliyense Internet. Mwachitsanzo, script: tcheru ( «Hello") adzakhala kuwonetsedwa osatsegula Internet Explorer pa zenera limene limati "Hello" pamwamba pa zenera waukulu. Pamene JS kuthandiza mungathe kusintha Pop-zenera (m'lifupi, kutalika, malo), onetsetsani kuti si nthawi yomweyo pambuyo alendo anapita tsamba, ndi pambuyo anapanga ake ena mpheto.

Kukhala malo ayenera kuganizira kwambiri za mokoma. Iwo ankadziwa kuti chuma online, ndithudi, amakopa chidwi cha alendo ake ndipo amapereka kwa mkaziyo. Koma tiyenera sangathe kwambiri adatengedwa zolembedwa kulemba, makamaka kwa Pop akuluakulu. Ambiri owerenga iwo amakonda kukwiyitsa. asakatuli zamakono zimene kutsekereza zinthu ngati masamba pa malo anu, kulola kuchotsa Pop akuluakulu ndi kuzimitsa njira yoyenera mu mindandanda yazakudya awo. Ngati ndi kotheka, muyenera kuti adzathe kulowa menyu ndi kubwezeretsa mphamvu kusonyeza deta ndi zolembedwa osatsegula.
