The result is everything but the first character. (The first line changes to "MCP01") This is my code:
function check() {
var c=$("#c").value;
c=c.replace(/[^A-Fa-f0-9]/, "");
return c;
}

it should be
$("#c").val(), and this logic won't work becauseDeactivatorhas bunch of valid hex characters in it – Esailija Commented Dec 23, 2012 at 11:30

Reset to default 8You should use /g flag to perform global replacement: -
c=c.replace(/[^A-Fa-f0-9]/g, "");
Note that, this approach may fail, because in "ABRET", it will only replace R and T, but ABE is not a valid hex digit.
If you want to keep just hex digit, then you should probably change your regex to: -
/\b[0-9a-fA-F]{6}\b/g
The above regex will only match Hex digit. So, just replace every substring, that doesn't matches the above pattern. Rest I leave to you to implement.
You can also modify the above regex to: -
/\b[0-9A-F]{6}\b/gi
With /i flag, the regex does case-insensitive matches. So, A is same as a.
These codes did not work enough good but they are great. Here is the code I ended up using:
var c=$("c").val();
var newc="";
var counter=0;
var newcstack="";
for (var i=0; i<c.length; i++) {
if (c.charAt(i).match(/[A-Fa-f0-9]/)) {
newcstack+=c.charAt(i);
counter++;
if (counter==8) {
newc+=newcstack;
counter=0;
newcstack="";
}
}
else {
counter=0;
newcstack="";
}
}
return newc;
