Indian Currency Validation using JavaScript

Thanks in Advance Radhika

maybe you should better describe what is a valid format, using just a few example is not always sufficient to behave correctly in the border cases — Eineki, May 12 '11 at 11:36

"it is very urgent" is considered [very rude](http://www.catb.org/~esr/faqs/smart-questions.html#urgent). Also: if you want good answers, format your question to be readable: your examples are hardly readable. — Joachim Sauer, May 12 '11 at 11:43
I agree they are not understandable. Something like this works better: http://stackoverflow.com/questions/5379231/displaying-currency-in-indian-numbering-format — mplungjan, May 12 '11 at 11:51

Here is a function that returns true if it is given a decimal number or a string representing a decimal number, and false otherwise.

I hope that is what you wanted.


function validate(s){
    return /\d+(.\d+)/.test(s)&&!/^0\d+/.test(s);
}

If you want the function also accepts natural numbers like "2", "0", or "10" then use this instead:


function validate(s){
    return /\d+(\.\d+)?/.test(s)&&!/^0\d+/.test(s);
}
