Okay whats this part? and how do i decode this?

 

<script>
var _0x4b77=["\x73\x72\x63","\x6F\x66\x66\x65\x72\x66\x72\x61\x6D\x65","\x67\x65\x74\x45\x6C\x65\x6D\x65\x6E\x74\x42\x79\x49\x64"];function check_gm(){if(document[_0x4b77[2]](_0x4b77[1])[_0x4b77[0]]!=_0x4b77[3]);setTimeout(_0x4b77[6],1000);} ;
</script>

 

Can someone tell me how i can decode this? and how did they encode it in the first place? Thanks!

 

If not can someone tell me how i can encode my js like this?!

function check_gm(){
  if(document.getElementById('offerframe')!=_0x4b77[3]);
  setTimeout(_0x4b77[6],1000);
};

 

But _0x4b77[3] and _0x4b77[6] isn't defined in your code snippet.
