Question

I need to create a regex to match this format: B001169875

Can someone help me?

Trying to make it work using jQuery Validate custom method:

  jQuery.validator.addMethod("brandnumber", function(value, element) {
       return  /B\d{9}/m.test(value);
  }, "Account number must start with B and be followed by 9 numbers.");

Answer 1

If it always starts with a B and is followed by 9 numbers then this will do it:

^B\d{9}$

And you could use it like this (depending on how you want to use it):

jQuery.validator.addMethod("brandnumber", 
    function(value, element) { 
        return /^B\d{9}$/m.test(value); 
    }, 
    "Account number must start with B and be followed by 9 numbers."
);
