You could use the data-parsley-pattern attribute, and use a regular expression to match numbers to 2 decimal places or zero.

^[0-9]{1,}\.?[0-9]{0,2}$

for example:

  • If the value is 1.00 then it will valid
  • If the value is 123.00 then it will valid
  • If the value is .00 then it will not valid
  • If the value is 1.000 then it will not valid

data-parsley-pattern="^[0-9]*\.[0-9]{2}$"

Also, remember to add a required attribute to your tag.
