Currency validation

Question

Please help with me writing a JavaScript Validation for currency/money field.

So please provide any regular expressions if u have :)

Answer 1

/[1-9]\d*(?:\.\d{0,2})?/

[1-9] - must start with 1 to 9
\d* - any number of other digits
(?: )? - non capturing optional group
\. - a decimal point
\d{0,2} - 0 to 2 digits

does that work for you? or maybe parseFloat:

var float = parseFloat( input );
