How to allow user only japanese numbers input for mobile field?
disabled other input.
This SO thread has almost exactly what you need.
In short, you use Regex to validate that only Japanese characters were used. You can use jquery.validate.js or write it all out yourself.
I'm using Spring MVC and dojo in my project.
We need to have an input for phone number by given format like: (###) ###-####
The phone number should automatically format as it's being typed.
The validation should be inside the text field it self with placeholder per each digit separated by '-'.
I tried to look over the web for an exist solution but I couldn't find any.
Can you try this library for phone number format?

I need to build multiple business forms with basic validations.
Example field types:
required field
date (datepicker)
time (timepicker)
email
money
integer number (+ optional min/max value)
decimal number (specify precision)
phone number
social security number
zip code
credit card number
masked text (+ optional regex validation)
field with server side validation
etc.
Is there a lightweight library or framework that provides some or most of those field types out of the box as well as the ability to create custom fields with validations?
You can these. I would think that a server-side validation is good too in addition to front-end validation
Use HTML5 (frontend) native validation

PHP some people have created their own class they shared Easiest Form validation library for PHP?
JQuery validation https://jqueryvalidation.org/
I recommand you to use vuito, since it's template-based and isomorphic you can share your validations between front and back-end super easily. The package weight less than 1.3kB.
I have a field called price, now how to validate this field by java script? It will take only integer value and dot. It may take decimal point or not.
e.g 200,200.00 both are valid.
How shall I do that?
There are many ways to achieve this.
Without the use of any 3rd party libraries i would recommend using regular expressions.
A possible pattern used to validate price would be
\d[\d\,\.]+
here is a tutorial on using regular expressions to validate fields in java-script

Hope this helps
I have this C# regex:
^\s?((?<qty>\d+)\s?/)?\s?[$]?\s?(?<price>\d{0,2}(?:\.\d{1,2})?)\s?$
and use MVC's data validation at the client. JavaScript says this regex is invalid, although C# works perfectly fine. Any idea how to get it to work for both C# and JavaScript, since it doesn't seem possible to provide a separate JavaScript Regex in the Data Validation annotations?
The regex validates a quantity and price. 4/$2.69 for example.
Javascript does not support named reference (?<…>…). You need to use
^\s?((\d+)\s?/)?\s?[$]?\s?(\d{0,2}(?:\.\d{1,2})?)\s?$
and refer qty and price as 1 and 2 instead.
Remove the group names (<qty>).
