Opomba urednika: Imamo prednost Prims.
   

1) Prizma

Označevalnik lahek in razširljivega sintakso, izdelani v skladu s sodobnimi spletnimi standardi. Uporablja se v več tisoč spletnih strani, tudi nekateri od tistih, ki jih obiščete vsak dan.

Kako namestiti?

Izberite in prenos predmetov želene konfiguracije na kraju samem. 2 Datoteke so prejeli, da Javascripts za CSS. Shranjene na strežniku v vašo spletno stran mapi.   za JavaScript, navedeno v vašo spletno stran med <head> in </head> način ali najti kodo.

Kako, da si ogledate kodo?

Ugotovi, da je jezik, ki ga želite prikazati s spremembo razred vrstico kode 1 (To spreminja barve odtenke glede na izbrano kodo): class=”language-js class=”language-php class=”language-html
<pre class="line-numbers"><code class="language-html">
Le code ici à déposer que vous souhaitez montrez aux internautes...!
</code></pre>
Prikaz entitées Mala Negativna stran Prism: Zaslon kode n & rsquo; ni nativne. Vi ste prisiljeni uporabljati znake ASII (subjekti HTML) Za prikaz kodo pravilno. najti ena stran opredelitev posameznega subjekta. Ponavljajoče uporaba obljublja težko nalogo. praktični nasveti: Za preprosto, uporabite urejevalnik za ogled besedila za urejanje hitreje z računalniško sintakso. primer : z Dreamweaver Prilepite besedilo v ustvarjanju del. V kode delu uredite svoje besedilo prikaže isto besedilo z subjekti HTML
 
   

2) Codemirror

Še ena najbolj naprednih deluje v obliko, ki se lahko spremeni s strani uporabnika. Koda prikaza teme se lahko spremeni za boljše branje. Nekatere težave za začetnike namestiti. Smo podrobno pojasnite, kako to storiti. 3 ukrepi, potrebni za prikaz 1) Vnesite pot od CSS teme. 2) Ustvarite spustni gumb. 3) Prilepi JavaScript za prikaz. 4) Prilepite kodo, ki jo želite prikazati. POMEMBNO : Za vsako novo kodo zaslonu boste morali spremeniti ID vsaki sliki v scenariju ne zamenja čas nalaganja strani in branje scenarijev. Glej razlago spodaj. Opomba urednika: da bi premagali samodejno ponovno natovarjanje, dodamo dogodek na Onchange do spremembe vseh sredstev naenkrat. >>Onchange =”javascript:location.reload()”<<

2 misli o „Pogled na računalniško kodo

  1. May I simply say what a relief to discover someone that
    really understands what they are discussing over the internet.
    You certainly understand how to bring an issue to light and make it important.
    A lot more people ought to read this and understand this side of your story.
    It’s surprising you are not more popular given that you most
    certainly possess the gift.

  2. Oh my goodness! an amazing article dude. Thanks Nevertheless I’m experiencing issue with ur rss . Don’t know why Unable to subscribe to it. Is there anyone getting an identical rss drawback? Anybody who knows kindly respond. Thnkx
