using PHP id in Javascript

You're creating multiple SELECT elements in this code, not one select element with <option>'s, which is what I think you are supposed to be doing.

You need to read about what the HTML for a proper SELECT looks like.

Then read about accessing options in a SELECT from JavaScript (preferably with a library, like jQuery).

This should give you enough knowledge to achieve what you want.
