Tab sis ib tug yooj yim qhov chaw yuav ua tau tej xov tooj nyob rau hauv tej kab, thiab nws muaj ib tug yuav tsum numeric code. Chaw - qhov no yog tsis yog ib tug qhov chaw dawb paug tej code, tej nqi ntawm lub nce mus nce los. Qhov no yog ib qho tseem ceeb heev lub cim. Yog li ntawd, tus nqi muaj NBSP. Yuav ua li cas yog nws? Tam sim no xav txog.

Tsis-tawg qhov chaw glued ob uas nyob ib sab lus, thiab nws tsis yog tsim nyog hais tias lawv ob qho tib si lawm. Thiab nyob rau hauv cov ntaub ntawv ntawm cov npe thaum lub caij tus xov tooj yog tsis muaj nyob rau hauv lub pawg lus cov ntsiab lus, tsevneeg yog ua mus rau lub sab saum toj kab.

Nyob rau hauv cov hnub, thaum lub MS Txojlus twb enjoyed zoo zoo, hypertext lus tsis tau tsim, tab sis lub xub ntiag ntawm ib tug tshwj xeeb cim yog Ameslikas npaj. Ib qho ntxiv uas yog & NBSP - dab tsi yog nws thiab yog vim li cas yog nws tsim nyog, nws tsis yog sai li sai tau tseeb.

Siv lub Npe

Qhov tseeb title yog tsis tau tawg, thiab cov lus nyob rau hauv nws tsis kis. Nws lub los yog mus raws li ib tug sab los yog lwm. Tsis muaj tus siv uas tsis yog-tawg qhov chaw yog ib qhov nyuaj rau ua.

Lub hypertext lus yuav zoo li no:

7. & NBSP; 5. & NBSP; ntawm FreeBSD Installation Guide

Nyob rau hauv HTML-nplooj nyob rau hauv lub browser title tooj yuav zoo li no: "7 5." thiab tag nrho, yog li dai kom zoo nkauj headers yuav nruj me ntsis zoo tib yam.

Muaj yog ib tug taw tes rau qhov twg koj yuav tsum tau them nyiaj mloog, yog hais tias koj siv cov ntawv nyeem thiab cov duab nyob rau hauv cov header. Qhov browser qhia tag nrho li qhia siv kuj raws nraim li tau hais tseg tuaj khiav. IMG tag yog nyob rau ntawm thaum pib ntawm lub kab, tab sis cov ntawv nyeem nyob tam sim ntawd tom qab hauv daim duab, nws yog tsim nyog los xav txog nws dav.

Cov kev siv ntawm ib daim ntawv lub ntsiab lus

Tsis muab los tso rau hauv cov ntawv nyeem, nyob rau hauv uas tsis tshua muaj mob, yuav pab tau. Feem ntau, headers thiab cov ntawv nyeem yog ib tug xov, tiam sis muaj ntau cim npe, xws li h2 thiab p.

Txav cov ntawv nyeem rau sab xis ntawm daim duab, nws yog heev yooj yim mus siv ntau yam & NBSP;.

Nyob rau hauv cov nram no piv txwv, koj xav kom tso saib icons hom ntawm cov ntaub ntawv, sau ntawv tom ntej no mus rau cov extensions ntawv nyeem.

Encoding ua nyob rau hauv PHP siv NBSP. Yuav ua li cas yog nws thiab yuav ua li cas siv tau? Nws tam sim no yuav ntshiab. Ib yam li ntawd, cov cim uas tsis yog-tawg qhov chaw no yog siv nyob rau hauv JavaScript.

Daim ntawv thov & NBSP; nyob rau hauv kab

Thaum ua kab (raws li nyob rau hauv lub neeg rau zaub mov, thiab nyob rau hauv lub browser) non-tawg qhov chaw tsis siv - heev kim yuav tsum tau siv es tsis txhob ntawm ib tug tseem ceeb cim "", raws li muaj ntau yam li rau "& NBSP;". Txawm li cas los, thaum cov hlua yog xa mus rau cov qhov tso zis kwj nyob rau hauv ib tug browser, koj yuav tau rov-encode txhua qhov chaw cim nyob rau hauv cov nyiaj uas tsis yog-tawg rau tej qhov chaw.

Tso zis nyob rau hauv ncha los yog print_r ib theem zuj zus ntawm ntau tshaj ib qhov chaw yuav tsis muaj lub Desired nyhuv thiab cov ntsiab lus "nkag". Piv txwv li (PHP):

1. ECHO "2 ____ Nyob zoo!"; // no "_" nruab nrab yog ib lub cim "."
2. ECHO "2 & NBSP; nyob zoo!"

Yuav muaj ib tug txawv nyhuv yog hais tias tus tag muaj ib tug leveling pov thawj. Nyob rau hauv thawj cov ntaub ntawv, cov xov tooj 2 yuav tsum sau rau ntawm sab laug ntug ntawm lub thaiv nyob rau hauv uas nws tau xaus lus, thiab cov ntawv nyeem "Nyob zoo!" - los ntawm txoj cai.

NBSP - dab tsi nws yog ib thiab yuav ua li cas thov li cas? ntaub ntawv tseem ceeb

Meanwhile, qhov teeb meem yog tsis nyob rau hauv qhov khoob. Tsis-xav luam cim yog ua tau heev npaum li cas, thiab lawv yuav tsis yeej ib txwm siv kom yog yog. Nws yog ib nqi nco ntsoov yuav ua li cas ua kom tawm cov ntaub ntawv MS Word cov neeg siv. Thaum koj yuav tau sau lo lus "thawj coj" nyob rau sab laug, tab sis nws lub npe txoj cai, feem coob ntawm cov pwm sib law liag ntau tabs - sai sai thiab nraaj.

Es tsis txhob raug teem tus nqi ntawm ib tug tab cim thiab leveling nws, tus neeg siv presses lub tab ib tug ob peb lub sij hawm thiab tau txais lub Desired nyhuv.

Ib tug zoo xws li cov teeb meem no nyob rau hauv lub markup lus HTML. "Привет, Мир, я 3-й раз ошибся..." - будет растянут по всей ширине блока, в которую эта строка была выведена. Muaj ntau developers tsis txhob siv tus cim tshwj xeeb kom raug, tsis txhob siv lub yeej raws li nws yuav tsum ua li cas, thiab cov no: "Nyob zoo lub ntiaj teb no, kuv yog tus thib peb lub sij hawm ua ib tug yuam kev ..." - yuav muab ncav us txog nyob rau hauv lub dav ntawm lub thaiv, nyob rau hauv uas cov hlua tej zaum yuav tso tawm kom pom.

Yog hais tias koj encode txoj hlua nyob rau hauv lub "Nyob & NBSP; ntiaj teb no, & NBSP; kuv & NBSP; peb & NBSP; lub sij hawm & NBSP; ua ib tug yuam kev ..." - cov yuav raws nraim txoj kev uas nws yuav tsum tau.

Paub thiab siv cov cim tshwj xeeb - ib tug heev zoo lub tswv yim. Tshwj xeeb tshaj yog yog tias koj muaj ib lub siab xav mus ua ib qho zoo thiab high-zoo cov nplooj ntawv uas cov ntsiab lus yog zoo thiab meej heev.
