Question

I tried a regular expression to validate a number with or without decimal with maximum 2 places.
I did this

var patt=  /(^\d+[.]?\d{1,2}+$)/g;

It is working in RegExr application.

but in chrome there is an error

SyntaxError: Invalid regular expression: /(^\d+[.]?\d{1,2}+$)/: Nothing to repeat

what wrong am I doing in this? Please help.Thanks.

Answer 1

Try this regexp:

var patt =  /^\d+(\.\d{1,2})?$/g;

What made your regexp incorrect is + sign after {1,2}.
