partials in innerHTML ?

I have a set of javascript functions that are reading json data
periodically to create innerHTML in a view.

Within that innerHTML, I need to put form(s) based on the structure
and content of a row in a table. I am thinking I will just have to
somehow hard-code this in html. Perhaps there is a better way?

I'm hoping someone here has a suggestion....I'm thinking maybe
partials (?) but the entire innerhtml is exactly that, just pure html.
Surely there has to be a way to accomodate this. Thanks Rvince
