Can I automatically switch user input method from fullwidth hiragana to halfwidth katakana when I focus in an input using javascript or PHP?

(1) I have a form of html inputs, some of which are allowed to type in halfwidth hiragana, the others are allowed to type in fullwidth katakana.

(2) Now, I need a way to automatically switch user keyboard input method between halfwidth hiragana and fullwidth katakana when user focus in the input in (1)

Is this possible or not?

This is a question that I don't have the expertise to answer, but I still like to make a few remarks.

First you had tagged the question this way:

Also, you may confused the Japanese scripts. There is a set of halfwidth characters for Katakana in Unicode, but not for Hiragana.

@Erland Sommarskog Thank you for your reply, I have edited my question, sorry for the mistake because I do not quite get used to Japanese

That's alright. I know pitiful little Japanese myself. But I happened to know this titbit.
