Question

var patt = path.match(/P[0-9][0-9][0-9]/);
patt = patt.substr(1);  //Remove P

while(patt.charAt(0) === '0') {   //Remove 0
    patt = patt.substr(1);
}

alert(patt);

patt is fixed to this format:
eg. P001 to P999

What I would like to do is very basic, just remove P and the leading 0 (if any). However, the code above is not working. Thanks for helping

Please use it like this:

var str = patt.join(”);
str = str.replace(/P0*/, ”);
