I am looking for the right pattern allowing to validate french numbers (positive integers) in an HTML input.

i.e. thousand separator is a "space".

Ex. of correct values:

  • 1
  • 12 345
  • 1 234 567

    • Ex. of incorrect:

  • 12x
  • 2x1
  • 1237

    • I have tried the pattern bellow, but it does not work

    <input pattern="([0-9]*[ ]*)*"/>

    Thanks for your help

    try this -

    <input pattern="[0-9 ]+"/>

    Note: there is a space before ]

    in javascript you can get actual number by replacing all " "(spaces) with "" and converting the string to integer
