Some encoded Javascript that I need in plain text

Question

Hey,

I'm having some issues trying to decode some javascript.. I have no idea what kind of encoding this is.. i tried base 64 decoders etc. If you can please help me out with this, here's a fragment of the code:

\x69\x6E\x6E\x65\x72\x48\x54\x4D\x4C","\x61\x70\x70\x34\x39\x34\x39\x3

Any ways I can get plain text from that?

Thanks!

Answer 1

The escape() function encodes a string.

This function makes a string portable, so it can be transmitted across any network to any computer that supports ASCII characters.

This function encodes special characters, with the exception of: * @ - _ + . /

The reverse of escape() is the unescape() function.

Try this:

alert(unescape("\x69\x6E\x6E\x65\x72\x48\x54\x4D\x4C\x61\x70\x70\x34\x39\x34\x39\x3"));

Edit: As J-P mentioned unescape isn't really needed here after all.

Answer 2

These are simply hex-values of symbols.

\x69 = i, etc. First several letters: "innerHTML", "ap…"

Answer 3

I think you should use window.unescape(), or unescape()

Answer 4

\xNN is an escape sequence. NN is a hexidecimal number (00 to FF) that represents a Latin-1 character.

Escape sequences are interpreted literally within a string. So:

"\x69" === "i" // true
