De-obfuscate Javascript code to make it readable again

Question

I hate to bring this here, while doing the learning of obfuscating the JS code, I encoded my code and then over wrote the orginal one without any backup :) Following is my obfuscated code.

var _0xf17f=["\x28","\x29","\x64\x69\x76","\x63\x72\x65\x61\x74\x65\x45\x6C\x65\x6D\x65\x6E\x74","\x69\x64","\x53\x74\x75\x64\x65\x6E\x74\x5F\x6E\x61\x6D\x65","\x73\x74\x75\x64\x65\x6E\x74\x5F\x64\x6F\x62","\x3C\x62\x3E\x49\x44\x3A\x3C\x2F\x62\x3E","\x3C\x61\x20\x68\x72\x65\x66\x3D\x22\x2F\x6C\x65\x61\x72\x6E\x69\x6E\x67\x79\x69\x69\x2F\x69\x6E\x64\x65\x78\x2E\x70\x68\x70\x3F\x72\x3D\x73\x74\x75\x64\x65\x6E\x74\x2F\x76\x69\x65\x77\x26\x61\x6D\x70\x3B\x20\x69\x64\x3D","\x22\x3E","\x3C\x2F\x61\x3E","\x3C\x62\x72\x2F\x3E","\x3C\x62\x3E\x53\x74\x75\x64\x65\x6E\x74\x20\x4E\x61\x6D\x65\x3A\x3C\x2F\x62\x3E","\x3C\x62\x3E\x53\x74\x75\x64\x65\x6E\x74\x20\x44\x4F\x42\x3A\x3C\x2F\x62\x3E","\x69\x6E\x6E\x65\x72\x48\x54\x4D\x4C","\x63\x6C\x61\x73\x73","\x76\x69\x65\x77","\x73\x65\x74\x41\x74\x74\x72\x69\x62\x75\x74\x65","\x70\x72\x65\x70\x65\x6E\x64","\x2E\x69\x74\x65\x6D\x73","\x66\x69\x6E\x64","\x23\x53\x74\x75\x64\x65\x6E\x74\x47\x72\x69\x64\x56\x69\x65\x77\x49\x64"];function call_func(_0x41dcx2){var _0x41dcx3=eval(_0xf17f[0]+_0x41dcx2+_0xf17f[1]);var _0x41dcx4=document[_0xf17f[3]](_0xf17f[2]);var _0x41dcx5=_0x41dcx3[_0xf17f[4]];var _0x41dcx6=_0x41dcx3[_0xf17f[5]];var _0x41dcx7=_0x41dcx3[_0xf17f[6]];var _0x41dcx8=_0xf17f[7];_0x41dcx8+=_0xf17f[8]+_0x41dcx5+_0xf17f[9]+_0x41dcx5+_0xf17f[10];_0x41dcx8+=_0xf17f[11];_0x41dcx8+=_0xf17f[12];_0x41dcx8+=_0x41dcx6;_0x41dcx8+=_0xf17f[11];_0x41dcx8+=_0xf17f[13];_0x41dcx8+=_0x41dcx7;_0x41dcx8+=_0xf17f[11];_0x41dcx4[_0xf17f[14]]=_0x41dcx8;_0x41dcx4[_0xf17f[17]](_0xf17f[15],_0xf17f[16]);$(_0xf17f[21])[_0xf17f[20]](_0xf17f[19])[_0xf17f[18]](_0x41dcx4);} ; 

Can anyone guide me the URL or any method to make it readable. I did this from this website and they seemingly provide on one way obfuscation services available on their website...this was my test code during a learning so would be greatful if anyone could help me out.

Answer 1

Here's a new automated tool, JSNice, to try to deobfuscate/deminify it. The tool even tries to guess the variable names, which is unbelievably cool. (It mines Javascript on github for this purpose.)

I tested with your code and worked as good as possible. =D
