在html输入字段中使用哪种模式来验证法语数字格式？

Question

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

ie 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

Answer 1

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
