Lag luam Scenario:
Muab txoj kev enables rau cov neeg siv yuav sau purchase yog requisitions ceev ceev.
Cov teeb meem ua lag ua luam:
Tus neeg twg ua lag ua luam nrog rau ntau pua neeg muag khoom.
Neeg muag khoom yog "hom" meej. Qhov no txhais tau hais tias ib tug vendor sells lub computer khoom (e.g. Dell) los sis khoom siv hauv chaw ua hauj lwm (e.g. Staples).
Peb yuav pab cov neeg siv tag leej twg rhawv purchase requisitions xaiv ib vendor uas koj siv tau li cas?
Kev hais haum ua lag ua luam:
Qha cov neeg muag khoom nyob rau hauv lub cev ntawm "hom".
Pab kom cov neeg siv kom xaiv "hom" ntawm cov khoom thiab muab ib txheej uas tsim nyog cov neeg muag khoom.
Kev tov:
Ib cov ntawv InfoPath twb tau tsim cov neeg enables sau hauv internet muas requisitions.
Ob tug InfoPath xaiv npe tswj vendor xaiv. Ua ntej, tus neeg siv ntawv twg xaiv ib tus "purchase yam". Qhov no txwv thib ob uas sau kom muaj xwb neeg muag khoom muag rau ntawd purchase hom. Qhov no nws yog ib tug classic cascading nco-down.
Neeg muag khoom muab cia rau hauv NTXHUAB kev cai sau kev cai txhua rau vendor pas xws li lub npe nrog rau, qhov chaw nyob thiab tshwj xeeb tshaj yog "yam".
Qhov Web site rau ib tug neeg InfoPath yuav haus cov dej uas siv los ntawm daim ntawv kev cai vendor iterates, rov qab xwb neeg muag khoom txuam ib supplied "yam".
Ua tau rau tus cov qhov Web site ntawm daim InfoPath.
Cov tshooj lus kawm:
- Ua ntej, nkawd yuav mus no lawv. Kuv yuav muaj tau najnpawb mus ua tus filtering nkaus li cov InfoPath thiab tsis tsim tej Web site rau functionality no. Txawm li cas los, cov neeg rau zaub mov yuav tsis muaj qhov yuav tsum tau filtering muaj rab peev xwm. Peb yuav muab txoj cai rau ib "hom" daim ntawv xaiv nyob rau hauv daim ntawv tsawm tsawv thiab rov qhib rau cov lus nug vendor, tab sis peb tsis tau mus ua hauj lwm kom zoo. Yog li no, yog yuav siv tau cov Web site qhov.
- Classic "cascading xaiv yuav sau li no" qhov teeb meem nyob rau hauv cov InfoPath tas li neeg rau zaub mov qab ntuj thiab muaj ntau yam zoo qauv muaj sia uas piav seb yuav kom daws tau qhov no li cas.
- Ib tug nqi rau ib sab nyob rau hauv daim ntawv vendor dawb paug tsis xa ib khoob hlua thaum hais los zoo li no: initItem["Vendor npe"]. Xwb, nws rov ib null.
Ib co sau ntawv:
- Kuv xa ib array[] cov neeg muag khoom vim kuv tau tej teeb meem uas rov qab ua ArrayList. InfoPath tau complaining txog nws thiab kuv tsis muaj sij hawm los yog tus inclination mus tua dua nws. Qhov no, tau mas, txo nws hwj ib co txwv rau tag nrho cov neeg muag khoom. Nws kuj compelled kuv siv ib trim() qauv rau cov array vim kuv ntxub cov tswv yim uas rov qaum 100 tus uas thov tus neeg muag khoom. InfoPath tsis tu, tab sis nws nagged rau kuv. (Dua, qhov no yooj yim dua ntaus InfoPath nyob ArrayLists).
- Kuv DVR ib GetSpecificVendorByName() ua kom zoo li, uas tej zaum yuav instructive.
