Question

I need a regular expression that matches currency values similar to here: Regex for Money

i.e. ‘1000’, ‘1000,0’ and ‘1000,00’

but I need it to work using javascript:

 var RE = /^-{0,1}\d*\.{0,1}\d+$/; //validates decimal format such as 1000.50
    if (locale == "fr") {
        RE = \d+(?:,\d{1,2})? //this line fails when validated using the javascript below
    }
    return (RE.test(valueToValidate));

Answer 1

Literal regex in javascript should be defined with / around the pattern

var RE = /^-{0,1}\d*\.{0,1}\d+$/; //validates decimal format such as 1000.50
if (locale == "fr") {
    RE = /\d+(?:,\d{1,2})?/ //this line fails when validated using the javascript below
}
return (RE.test(valueToValidate));
