mascherare codice js

[luisa227]

cè possibilità di "mascherare" il codice js in qualche modo? cioè fare in modo che non sia immediatamente accessibile? grazie

No. Puoi solamente criptarlo (rallentandone il funzionamento), ma come è in grado di decriptarlo il browser del visitatore sono in grado di decriptarlo anch'io. Quindi la risposta è no. Javascript è un linguaggio aperto.

ok grazie

... tanto poi se qualcuno chiede di decriptare il tuo codice lo aiutiamo uguale

bene! ci ho ragionato dopo... quindi un codice criptato come faccio a decriptarlo? esistono programmi utili?

ho trovato questo codice js ad esempio che credo sia criptato: ho provato un decript da questa pagina http://www.w3facile.com/html/come-de...avascript.html ma nulla...

Non so a cosa ti possa servire, comunque:

<script type="text/javascript">window.fbAsyncInit = function() {FB.init({appId: , status: true, cookie: true, xfbml: true});	FB.Event.subscribe('edge.create', function(href, widget) { if (fblike_redirect) {document.location.href=fblike_redirect;} else {document.getElementById('likediv').style.display = 'none';document.getElementById('afterlike').style.display = 'block'; }});};(function() {var e = document.createElement('script'); e.async = true;e.src = document.location.protocol +'//connect.facebook.net/en_US/all.js';document.getElementById('fb-root').appendChild(e); }());</script><fb:like href="" send="false" width="450" show_faces="true" font=""></fb:like>

Senza troppi sforzi... installati il componente aggiuntivo di firefox "Web Developers", dopodiché cerca Visualizza -> "Sorgente generato" e ti troverai col codice in chiaro...

[luisa227]

perfetto!!! non ho capito la formula per arrivare (a parte l'uso di firefox) al codice originale, ma ringrazio tutti quanti!

altra domanda: cè modo di ri-criptare lo stesso codice, ma in modo "diverso"? cioè non mi interessa che sia poi facilmente decriptato, ma mi interessa che non sia uguale al js che già ho. Spero di essermi spiegata bene, grazie ancora.
