Input Fields as part of MathJax

From https://groups.google.com/d/msg/mathjax-users/ueAqvvR1F1g/doNggSQgJSoJ

Is it possible to insert an input field into a given equation display by mathjax so that the user can make an input there?

See the forminput extension in the repository of user-contributed extensions for something that may do what you want, but note that this may not work in all output modes.
