You can always pick up the fields by their ID, the fact that they are not wrapped in a form makes no difference:

$('#businessname')

It is not valid HTML, however, and you really should use a <form> around form elements.

Why are you not using one?

For semantic and valid markup, you do need a <form> tag. No question of its not being there.
