Is there any free Javascript Obsfucator available?
Actually I just want the obsfucator to do two things...
1. Remove Comments
2. Rename Functions and Variables

You may find JSMin useful (at least for the first objective).

I downloaded the PHP code and made a php file to upload the required js file.
Like this:
[PHP]<?php
//file name: minify.php
if (!isset($_POST['Submit']))
{
?>
<html>
<form action=minify.php method=post enctype="multipart/form-data">
<input type=file name=js></input>
<input type=submit name=Submit value=Minify>
</form>
</html>
<?php
}
else
{
include('jsmin-1.1.0.php');
if ($_FILES['js']['error']>0)
die ('Error Uploading File');
$file_js = fopen($_FILES['js']['tmp_name'],"r");
$js = fread($file_js,$_FILES['js']['size']);
//echo $js;
$min = new JSMin;
$minified = $min->minify($js);
//echo $minified;
}
?>[/PHP]
But it gives this warning... Missing argument 1 for JSMin::__construct()
What to do...
PS: I don't understand OOP Concepts :(
I suggest you ask in the PHP forum.

Yeah, you are right!!
My fault!!
I use firefox to compress it.
wrap your code in a function, then compress by using the .toSource() method on the function.
Example: -
function BS(){
-
-
-
function el2(tid) {
-
return document.getElementById(tid);
-
}
-
-
function tags(elm, tid) {
-
if (tid) {
-
if (elm.isString) {
-
elm = el(elm);
-
}
-
return obValsl(elm.getElementsByTagName(tid));
-
}
-
return obValsl(document.getElementsByTagName(elm));
-
}
-
-
}
-
-
-
alert(BS.toSource())
-
/* returns:
-
function BS() {
-
function el2(tid) {return document.getElementById(tid);}
-
-
function tags(elm, tid) {if (tid) {if (elm.isString) {elm = el(elm);}return obValsl(elm.getElementsByTagName(tid));}return obValsl(document.getElementsByTagName(elm));}
-
} */
-
remember to remove the first and last line of the resulting text, the function wrapper.

Nice tip (for compression, at least)!

By the way, is this just to cut down on the size of the script? This is what minification is for.
@acoder
Yeah, coz I ended up making at least 10 js files of all approx 25 kb. So I wanted to cut down the size. And I know the actual code size (w/o comments and spaces) is approx 15 kb, may be less than that.
@rnd me
Cool!! Thanks... :)

So, did you manage to cut it down in size?

I didn't do it yet...
Will do after testing.
Will tell you how much file size reduces...
remember that in javascript, variable names are case-sensitive, so performing global replaces on compressed code could be an easy way to obfuscate names.
if you have a funciton or prototype for doing mulitple replaces, you could feed it a an array of function names, and have it substitute a serial number for each.
continuing above, -
-
String.prototype.substitute = function (r) {
-
O = this;
-
for (z = 0; z < r.length; z++) {
-
tre = new RegExp(r[z][0], "gm");
-
O = O.replace(tre, r[z][1]);
-
}
-
return O;
-
}
-
-
-
function serial(dig) {
-
var bb = "";
-
if(!dig){ dig=5; }
-
for (var q = 0; q < dig; q = q + 1) {
-
bb = bb + String.fromCharCode(Math.round(Math.random() * 25 + 65));
-
}
-
return bb;
-
}
-
-
var subs=[
-
["el2",serial()],
-
[ "tags", serial()]
-
] //end sub array
-
alert(BS.toSource().substitute(subs) )
-
-
So, did you manage to cut it down in size?
Yeah, quite a lot.
A 32kb well commented JS was reduced to 19 kb.
And a 15 kb, non-commented JS reduced to 14 kb (not too much tho :p)

Every little helps, eh?
If you're using long names for variables, functions, etc. you may want to replace those too.

Yeah, I wanted to, but the thing you referred to didn't do that :p
And I don't want to do the find replace thing. B'coz with that, when I would do any change, after doing that with the original (commented) file, I would need to do the whole find-replace thing again.
So I wanted a one-click-solution, so that after making any change, I can get the minified* version quickly and upload it to server again. * term used by that guy who made that program.

Try YUI Compressor, Packer or ShrinkSafe (Dojo).
