Hauv cov ntaub ntawv thev naus laus zis thiab kev tshawb fawb hauv computer, tus qauv ntawm kev siv ib txoj kev hloov pauv ntawm cov ntaub ntawv tsis hloov pauv tau hu ua Unidirectional Data Flow.
Vim li cas hnov qab siv cov ntaub ntawv unidirectional ntws?
React tsis txhawb nqa ob txoj kev khi kom paub tseeb tias koj ua raws li cov ntaub ntawv huv si ntws. Qhov txiaj ntsig tseem ceeb ntawm txoj hauv kev no yogcov ntaub ntawv ntws thoob plaws koj lub app hauv ib qho kev taw qhia, muab koj tswj tau zoo dua. Nyob rau hauv cov nqe lus ntawm React nws txhais tau tias: lub xeev tau dhau mus rau qhov pom thiab rau cov khoom me me.
Dab tsi yog unidirectional thiab bidirectional cov ntaub ntawv ntws?
Bidirectional thiab unidirectional dataflow hais txog ciam teb, thaj chaw, thiab cov ntaub ntawv qhia txav ntawm cov kev pabcuam thiab kev pom. Kev khi yog hais txog kev sib raug zoo ib leeg-ib-ib qho, thaum bidirection thiab unidirection hais txog kev sib raug zoo ntawm cov khoom.
Vim li cas unidirectional flow tseem ceeb?
Yog tias cov txheej txheem tsis ua raws li qhov raug thaum muab cov ntaub ntawv rau hauv DOM, nws ua rau muaj teeb meem loj xws li kev ua haujlwm nyiaj siv ua haujlwm thiab lwm yam. Qhov no yog vim li cas peb xav tau cov ntaub ntawv unidirectional ndlwg mechanism, uas xyuas kom meej tias cov ntaub ntawv yog txav los ntawm sab saum toj mus rau hauv qab thiab cov kev hloov no yog propagated los ntawm lub system.
unidirectional architecture yog dab tsi?
Nyob rau hauv ib qho unidirectional daim ntawv thov architecture, hloov pauv hauv daim ntawv thov saib txheej ua rauua nyob rau hauv cov ntaub ntawv txheej. Cov kev hloov no ces propagated rov qab mus rau qhov pom. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ntawm no tias qhov kev pom tsis cuam tshuam ncaj qha rau cov ntaub ntawv thov.
