I have a bookmarklet, and i want to hide/encode the JavaScript code within, something like a compiled code, so that the original code wont be available for the users of the bookmarklet;
Can i do this, and if yes, how ?

Not really - you can obfuscate it, though. But why is this tagged `php`? – Pekka Jan 12 '13 at 17:57

the bookmarklet was developed under yii mvc, and it uses php, html, js – Ionut Flavius Pogacian Jan 12 '13 at 17:58

this is what i mean, obfuscate ... and is this the only method ? – Ionut Flavius Pogacian Jan 12 '13 at 17:59

yes. You can't really compile JavaScript code. You'd have to build a browser extension to have a compiled executable. Re obfuscating, look for `javascript obfuscation` – Pekka Jan 12 '13 at 18:02

See e.g. [What is the best javascript obfuscator?](http://stackoverflow.com/q/522064) – Pekka Jan 12 '13 at 18:03

Maybe this site can help you: http://www.javascriptobfuscator.com/
About it:
Free Javascript Obfuscator is a professional tool for obfuscation of javascript. It Converts JavaScript source code into scrambled and completely unreadable form, preventing it from analysing and theft.
I gave it this input test:
alert("Hello World")
Output:
var _0x7d3e=["\x48\x65\x6C\x6C\x6F\x20\x57\x6F\x72\x6C\x64"];alert(_0x7d3e[0]);
You can test it in your Firefox Scratchpad (Shift + F4) or in Google Chrome console (F12).

This is from [About Page](http://www.javascriptobfuscator.com/Javascript-Obfuscator.aspx). I don't understand what you mean. – Ionică Bizău Jan 12 '13 at 18:58

Meaning that would take someone about 2 seconds to decode. As obfuscatiors go, (and this is a fools errand anyway) it's not a very good one. – steveax Jan 12 '13 at 19:04
