JavaScript RegEx expresssion -


i need compose expression allow number or decimal point, 1 decimal.

allowed formats

100.00, 100

but not

'100d.00, a100, -100, 100.000.000.00'

for goal, far have this:

/[^0-9$.]/g

any community appreciated.

i think /^\d+(\.\d{2})?$/ should work. if need more 2 digits after decimal point /^\d+(\.\d+)?$/.
