Regex Javascript Numbers Comma Separated | > | >= <=

Question

I'm using this Regex to validate numbers with decimals (comma separated)

/(^\d*\,?\d*[1-9]+\d*$)|(^[1-9]+\d*\,\d*$)/

but i need to change it so that it can also validate numbers higher than 5000 and between 3000 and 1000000

I'm not a Regex expert even though i have read several tutorials i'm still unable to find a solution...any help is appreciated. thanks in advance.

Answer 1

This will match numbers between 3000 and 1000000, inclusive, allowing an optional fractional part separated by a coma:

 /^([3-9][0-9]{3}(,[0-9]+)?|[1-9][0-9]{4,5}(,[0-9]+)?|1000000)$/

You can test it here .

This will match numbers greater or equal to 5000, allowing an optional fractional part separated by a coma:

 /^([5-9][0-9]{3}|[1-9][0-9]{4,})(,[0-9]+)?$/

You can test it here .
