Knowing the language used in a form

Question

I'm working on a site with forms that require a certain language to be used. (Something like a dictionary). I want to know if there is a way in JavaScript/HTML to check the language. For example, if I need the input in Japanese and the user gives me an English word, it is detected as an error.

Answer 1

You could take a look at the Google AJAX Language API and there's an example of language detection.

Answer 2

No, there is not a way to do this with straight java/html. The best you could do is hope that UTF-8 is the encoding, and then you check the character class. But that still doesn't really tell you which language is used.

Answer 3

No, you need to implement a function or use a specific library.
