Kuv tsis xav tias cov web browsers yuav ploj mus nrog cov loj loj tom ntej ntawm lub vas sab, tab sis kuv yuav tsis xav tsis thoob yog tias browsers yog rov ua dua ntawm qee qhov taw tes kom haum zoo dua li cas peb surf hauv Internet.
Tsis yog tias web browsers tsis tau hloov txij li thaum lawv tau tshwm sim. Lawv tau dhau los ntawm kev hloov loj heev, tab sis nws tau ua cov txheej txheem tshiab xws li Java, Javascript, ActiveX, Flash, thiab lwm yam ntxiv-hauv lub creeping mus rau hauv qhov browser.
Ib yam uas kuv tau kawm los ua ib tug programmer yog tias thaum ib daim ntawv thov evolves nyob rau hauv txoj kev uas nws tsis yog pib tsim rau, nws pib tau txais clunky. Txij ntawm no mus, nws yog qhov zoo tshaj plaws los pib ntawm kos thiab tsim ib yam dab tsi uas yuav siv rau txhua yam koj xav kom nws ua.
Thiab nws lub sijhawm siab kawg rau qhov no. Qhov tseeb, thaum kuv nyuam qhuav pib programming web daim ntaub ntawv rov qab rau hauv lub lig 90's, Kuv xav tias nws yog lub sij hawm siab rov qab los ua ib qho web browser tshiab. Thiab lub vas sab tau txais ntau ntau dua txij thaum ntawd los.
Web Browsers Muaj Mob Tsis Muaj Mob Ua Txhua Yam Ua Peb Xav Tau
Nws yog qhov tseeb. Web browsers yog horribly tsim thaum koj xav txog dab tsi peb thov kom lawv ua hnub no. Yuav kom nkag siab qhov no, koj yuav tsum xub nkag siab tias cov web browsers tau pib tsim, qhov tseem ceeb, lo lus processor rau lub vas sab. Cov cim lus ntawm lub vev xaib yog zoo tib yam rau cov hom lus cim rau cov lus hais. Thaum Microsoft Word siv cov cim tshwj xeeb los xaiv cov bold ntau cov ntawv nyeem lossis hloov nws cov ntawv, nws tabtom ua qhov qub tshaj plaws: Pib Bold. Cov ntawv nyeem. Kawg Bold. Uas yog tib yam peb ua nrog HTML.
Dab tsi tau tshwm sim hauv nees nkaum xyoo tas los no yog qhov no lo lus processor rau lub vas sab tau raug hloov kho rau txhua yam peb xav kom nws ua. Nws zoo li ib lub tsev uas peb tau muab lub tsev rau hauv qhov chaw nres tsheb, thiab lub qab nthab rau hauv chav pw, thiab hauv qab daus rau hauv ib chav ua noj, thiab tam sim no peb xav kom xa chav cia rov qab thiab muab tso rau hauv ib chav tshiab lub tsev - tab sis, peb tab tom khiav mus rau txhua yam teeb meem hluav taws xob thiab cov kav dej vim hais tias tag nrho peb cov xov hlau thiab cov kav dej tau txais li ntawd vwm nrog tag nrho lwm yam ntxiv uas peb tau ua.
Tias yog dab tsi tau tshwm sim rau cov web browsers. Niaj hnub no, peb xav siv peb lub web browsers raws li ib tug neeg rau ib daim ntawv thov nkag web site, tab sis lawv yeej tsis tau meant ua li ntawd.
Qhov teeb meem tseem ceeb kuv tau nrog web programming, thiab ib qho ntawm lub ntsiab yog vim li cas browsers ua neeg pluag cov neeg siv rau hauv web daim ntaub ntawv, yog tias muaj tsis muaj txoj kev zoo rau kev sib txuas lus nrog lub web server. Nyob rau hauv qhov tseeb, rov qab ces, tib txoj kev koj yuav tau txais cov ntaub ntawv los ntawm tus neeg siv yog rau lawv mus nias ib yam dab tsi. Yeej tseem zoo, cov ntaub ntawv tsuas siv tau thaum twg ib nplooj ntawv tshiab tau los.
Thaum koj xav li cas, qhov no ua rau nws nyuaj rau daim ntawv sib tham sib hais tiag tiag. Koj tsis tuaj yeem muaj leej twg ntaus ntawv rau hauv ib lub thawv ntawv thiab tshawb xyuas cov ntaub ntawv ntawm tus neeg rau zaub mov thaum lawv ntaus. Koj yuav tau tos lawv kom nias lub khawm.
Cov tshuaj: Ajax.
Ajax stands rau Asynchronous JavaScript thiab XML. Yeej tseem zoo, nws yog ib txoj kev ua yam uas cov laus hauv web browsers ua tsis tau: sib txuas lus nrog cov neeg siv qhov web site tsis tau hu cov neeg tau txais kev pab rov tuaj rau nplooj ntawv. Qhov no yog ua tiav los ntawm XMLHTTP ActiveX khoom hauv Internet Explorer lossis XMLHttpRequest hauv yuav luag txhua qhov browser.
Yeej, qhov no yog qhov tso cai rau lub web programmer ua yog pauv cov ntaub ntawv ntawm tus neeg thiab cov neeg rau zaub mov li yog hais tias tus neeg siv tau rov qab nplooj ntawv tsis muaj tus neeg siv puas tau ua dua los ua qhov nplooj ntawv.
Suab zoo heev, puas yog? Nws yog ib kauj ruam loj rau pem hauv ntej, thiab nws yog qhov tseem ceeb vim li cas qhov kev siv Web 2.0 yog cov kev sib tham sib ntau thiab yooj yim dua-siv-tshaj li qhov dhau los ntawm qhov web applications. Tab sis, nws yog ib qho tseem ceeb heev. Yeej, tus neeg yuav xa cov neeg tuaj tawm rau qee cov ntaub ntawv, thiab nws xa ib ntu ntawm phau ntawv rov qab, tawm hauv tus neeg mob nrog txoj haujlwm txhais cov ntawv nyeem. Thiab tom qab ntawd, tus neeg siv cov khoom siv hu ua Dynamic HTML ua rau nplooj ntawv zoo li sib tham.
Qhov no yog qhov txawv me ntsis li qhov tus neeg ua haujlwm thov kev pab-neeg ua hauj lwm ua haujlwm zoo li cas. Tsis muaj kev txwv ntawm cov ntaub ntawv rov qab mus, thiab nrog tag nrho cov duab tsim nrog lub qhov muag ntawm cia tus neeg muab lub vijtsam rau ntawm yoov, siv Ajax cov tswv yim ua kom tiav hauv lub vas sab yog zoo li dhia dhau ntawm hoops mus txog tod.
Web Browsers yog Cov Kev Siv Haujlwm ntawm Lub Ntiaj Teb
Microsoft paub nws rov qab rau hauv 90's. Tias yog vim li cas lawv tau mus ua tsov rog nrog Netscape, thiab yog vim li cas Microsoft rub tsis muaj punches hauv winning ntawd tsov rog. Hmoov tsis - tsawg kawg rau Microsoft - qhov kev ua tsov ua rog tshiab muaj nyob, thiab nws tabtom tawm tsam ntau hom platforms. Mozilla Firefox yog tam sim no tau siv li ntawm 30% ntawm cov neeg siv Internet, txawm tias Internet Explorer tau pom qhov sib txawv ntawm cov lag luam los ntawm ntau tshaj li 80% mus tshaj 50% hauv tsib xyoos dhau los.
Nrog rau lub vas sab tam sim no zoo li Web 2.0 thiab Office 2.0 nqa dab tsi yog cov qauv siv duab rau lub vas sab, muaj kev ywj siab ntau tshaj nyob rau hauv kev xaiv ntawm kev khiav hauj lwm lub tshuab, thiab ntau qhov tseem ceeb ntawm kev txhim kho browsers. Ob qho tib si uas tsis yog xov zoo rau Microsoft uas nws Internet Explorer browser nyhav ua yam txawv dua li cas txhua qhov browser ntau tshaj plaws. Ntxiv dua thiab, tsis yog xov xwm zoo heev rau Microsoft.
Tab sis ib qho zoo tshaj plaws txog txoj kev siv cuab yeej ntawm kev khiav hauj lwm yog tias koj tuaj yeem siv cov khoom siv los tsim koj qhov kev sib txuas. Koj kuj muaj kev tswj ntau npaum li cas koj nkag tau nrog cov khoom ntawd, thiab muaj peev xwm txawm tsim koj tus kheej hloov chaw. Nrog lub web programming, nws yog qhov nyuaj rau qhov theem ntawm kev tswj, mas vim tias cov web browsers tsis tau pib npaj los ua cov neeg tau ntsej muag rau ib daim ntawv thov loj - tsis tshua muaj kev khiav hauj lwm rau yav tom ntej.
Tab sis, ntau thiab ntau dua, uas yog yam lawv ua. Google Docs twb muab ib lo lus processor, spreadsheet, thiab kev nthuav qhia software. Muab qhov no nrog Google tus xa ntawv tuaj, thiab koj muaj koj qhov chaw ua hauj lwm software tsim lag luam. Peb yog qeeb, tab sis qhov tseeb, tau txais qhov qhab nia uas feem ntau peb cov ntawv thov yuav muaj nyob hauv online.
Qhov muaj npe nrov ntawm Smartphones thiab PocketPCs yog tsim kom muaj tag nrho lub hauv paus tshiab rau hauv Internet. Thiab, thaum lub sijhawm tam sim no rau Txawb Internet mus koom nrog lub 'tiag' Internet , qhov no tsis txo tus neeg toj roob hauv pes los ua ib tus neeg tseem ceeb hauv kev sib tham ua li cas "Internet of the Future" yuav saib.
Ib qho tseem ceeb yog tias nws tsim lub hauv paus tshiab hauv cov qhov web browser wars. Yog tias Microsoft tseem nyob nrog rau nws lub Internet Explorer browser, nws yuav tsum tau mus cuag dominance ntawm mobile devices nrog "Pocket IE," Microsoft lub Internet Explorer rau Mobile browser.
Ib qho ntxiv nthuav txog kev txawb xov tooj li cas yog nkag mus rau hauv Internet yog siv cov kev siv Java hloov cov kev cai ntawm cov web portals. Tsis txhob mus rau Microsoft Live lossis Yahoo, cov neeg siv khoom siv mobile download tau Java versions ntawm cov websites. Qhov no tsim ib qho kev sib tham sib uas yog tib yam li txhua tus thov kev pabcuam-neeg rau zaubmov tsis tagnrho cov kev pitfalls ntsib los ntawm cov web browsers.
Nws tseem qhia tau hais tias cov vev xaib loj yog txaus siab los tsim lawv qhov chaw rau ib daim ntawv thov kev txhim kho tshiab.
Tus Browser ntawm lub neej yav tom ntej
Kuv wouldn 't tso cov bets uas peb' dhau pom ib qho kev hloov loj hauv qhov web browsers yog tsim txhua sij hawm ze yav tom ntej. Seb puas los yog tsis Web 3.0 yuav qhib rau hom tshiab ntawm tus browser los yog mus hauv ib qho kev qhia txawv kiag li yog leej twg xav twv ntawm qhov no.
Tab sis, tib lub sijhawm, Kuv tsis xav ua kom pom ib hom tshiab tshiab ntawm qhov browser kiag sau dua tshiab nrog cov kev siv web site hauv hlwb tig lub web. Nws yuav siv ib tug neeg tseem ceeb uas tsim nws, thiab cov players loj xws li Google thiab Yahoo thiab lwm tus neeg tom qab nws, uas tsis yog qhov yooj yim tshaj plaws los ua kom tiav, tiam sis nws ua tau.
Dab tsi yuav qhov browser ntawm lub neej yav tom ntej yuav zoo li? Kuv xav tias nws yuav zoo li peb cov browsers tam sim no, ActiveX, thiab Java los tsim ib yam dab tsi uas yuav ua tau ob qho tib si mini-operating system thiab ib txoj kev loj hlob.
Rau koj thiab kuv, nws yuav zoo li kev ntsaws los ntawm peb qhov chaw ua hauj lwm daim ntawv thov, seamlessly switching ntawm ib lo lus processor thiab spreadsheet, thiab cia li raws li seamlessly hloov mus rau ib qho kev ua multiplayer hauv online roleplaying.
Yeej tseem zoo, txhua lub vas sab yuav yog daim ntawv thov ntawm nws tus kheej, thiab peb yuav yooj yim mus ntawm ib lub website / daim ntawv thov mus ntxiv.
Dab tsi koj xav tias qhov Web 3.0 yuav coj?
