これは私にとって本当にうまくいっているので、試してみてください。

// start and end in a digit and require 8 digits inbetween (so total of 10 digits required).
// allow a single space between any digit (so this is valid "0 1 2 3 4 5 6 7 8 9" ... 19 characters ... but our minLength and maxLength validation protects us from this)
// minLength 10 means "0123456789" is the shortest valid input.
// maxLength 14 means "01 23 45 67 89" is the most spaced we can be (i.e. max 4 spaces allowed... they could be anywhere in the string e.g. "12 123 123 1 1")
