Naomba msaada kodi hizi za javascript

Wakuu habari zenu. Nahitaji msaada katika javascript. Ndio kwanza beginner but nina idea kidogo. Najua css na html.

Nimetengeza page with fields.

Sasa kuna sehemu nimeweka ivi:


Sasa mimi nnachotaka, kwa mfano user akichagua Blah blah katika option ua mwanzo, kisha katika option ya pili akichagua 123 basi itoe majibu lets say "umepata".

Vipi ntaweza kutumia javascript kuiambia browser kuwa kama kachagua blah blah na 123 jibu liwe umepata?

Nawasilisha

Weka options

Javascript hutumika ku verify correct user input..kama ungetaka app hyo user ndo aingize data ndo ingekua na maana kutumia javascript kuverify..

Sasa tayar ww unainput unazotaka user aweke..mi naona simplest way n kutumia server side language kama PHP o JSP o whatever unayoimaster..

Fanya kuzipokea hzo data af umrudishie user ujumbe uutkao.

Logic ya solution duuuuh.

1. Assign unique ID kwa hizo select tag
2. Register change event handler kwa hizo select tag, on document ready event
3. Tumia if control logic ku evaluate hiyo condition ukianza na first selection then second selection
4. ...

Kwanza inabidi uzipe id hizo select fields zako ili upate urahisi wakati unaita values. Halafu pia kwenye options inabidi uweke property ya value badala ya id.

Umemaliza kila kitu hapo mkuu, ila huyu ndugu yetu ni beginner utamtesa ukimpa maelekezo matupu

deejaywillzz,

Mkuu asante sana nashkuru kwa msaada wako. Imekubali, lakini kuna kitu kimoja samahani kama ntakusumbua, nlikuwa nimeweka <td> </td> sasa nataka hio "umepata" to appear katika hiyo table data.

Alert inakuja browser popup, document.write inaleta results lakini tatizo haikai katika iyo table data cell, inafanya kama inaingia another page na kuweka iyo result.

Mkuu kwa uelewa wangu javascript ni clientside scripting language, sasa izo action za kuselect option haziwi submitted action ni apo kwa apo tu within browser, ingekuwa form inakuwa submitted ndo ingehitajika serverside scripting language.

Kwanza inabidi hiyo <td> yako uipe unique id, kwa mfano <td id="mfanoResults"></td> kisha replace mstari wa alert kwenye java script yako na hii code document.getElementById("mfanoResults").innerHTML = "umepata";

Nawashkuru kwa msaada wenu hasa hasa software engineer na deejaywillz.
