VistasHow to generate QuestionnaireResponse using LHC-Forms (LForms)
I'm working through the capabilities of LHC-Forms (LForms) in github here:
https://github.com/lhncbc/lforms-fhir-app
Looking at the example here:
https://lhcforms.nlm.nih.gov/sdc
There is a button that lets the user see a FHIR QuestionnaireResponse based on the form and the data entered in the form. Using the debugging/Elements tool in my browser, the button has a javascript:void(0) method for href. What does LForms use to generate the QuestionnaireResponse from the form displayed on the page? Is this documented somewhere?

Documentation for LHC-Forms is at http://lhncbc.github.io/lforms/. Following the "Exporting FHIR" link on the left (http://lhncbc.github.io/lforms/#retrieving-fhir-data), you will see it provides this API call for getting back a FHIR Resource:
LForms.Util.getFormFHIRData(resourceType, fhirVersion, formDataSource, options)
So, for an R4 QuestionnaireResponse, one could write:
LForms.Util.getFormFHIRData("QuestionnaireResponse", "R4")
Incidentally, questions about LHC-Forms are more likely to get noticed on the "questionnaire" stream at chat.fhir.org, or by posting an issue on the GitHub package (though sometimes I miss the notice about those).
