jQuery validate and the comma decimal separator
Oh this is such a simple and good solution that I must put it on my blog at least for my own future reference. Big THANKS to Lenard Gunda for writing this blog post

If you live outside the US and have problems with getting client side validation accepting comma decimal separator in input fields - just overwrite jQuery validation range and number methods with these javascript lines in the end of all your javascript loading.
$.validator.methods.range = function (value, element, param) { var globalizedValue = value.replace(",", "."); return this.optional(element) || (globalizedValue >= param[0] && globalizedValue <= param[1]);}$.validator.methods.number = function (value, element) { return this.optional(element) || /^-?(?:\d+|\d{1,3}(?:[\s\.,]\d{3})+)(?:[\.,]\d+)?$/.test(value);}
