client validation using jQuery validate for curren

问题:

I have a problem using jquery.validate on my asp.net mvc 3 app.

At least in Spain we use the "," to split a number from its decimals. Ok, using server side validation, if I put something like:

12.55 when the server validate it, it says that the value is not valid. If I put: 12,55 it works.

So far so good, but if I use jQuery validate, it says that 12,55 is invalid and 12.55 is the valid one. So, the client pass the validation but the server not, or the client doesnt pass but the server would.

So... can I change the locale for that kind of validation?

Thank you.

PS: How the server knows that I want to validate using "," and not "."? I don't remember if I specified that somewhere.

Probably you should include localization files:

http://ajax.aspnetcdn.com/ajax/jQuery.Validate/1.7/localization/messages_es.js

http://ajax.aspnetcdn.com/ajax/jQuery.Validate/1.7/localization/methods_de.js

In Germany one uses the same rules for numbers, so you can use methods_de.js or just include

jQuery.extend(jQuery.validator.methods, {
    number: function(value, element) {
        return this.optional(element) ||
               /^-?(?:\d+|\d{1,3}(?:\.\d{3})+)(?:,\d+)?$/.test(value);
    }
});

Here the list of files hosted by Microsoft CDN for the version of 1.6. The version 1.7 has the same files.

UPDATED: See demo here.

You could try configuring your web application to use the locale of the client web browser:

<system.web>
    <globalization requestEncoding="utf-8" 
                   responseEncoding="utf-8"
                   culture="auto" 
                   uiCulture="auto" />
    ...
</system.web>

This will use the browser culture for server side validation. As far as the client side validation is concerned it already uses the browser culture. So this ensures that both match.
