[Javascript] Number validation with digit grouping

[Dan Costea]

I wrote a function for you:

   function floatTest (sNr)
   {
    var reFloatF1 = /^((\d+(\.\d*)?)|((\d*\.)?\d+))$/; // format 1
    var reFloatF2 = /^((\d+(\,\d*)?)|((\d*\,)?\d+))$/; // format 2

    return (reFloatF1.test (sNr) || reFloatF2.test (sNr));
   }

This should solve your problem.

Dan.
