🚦 Design Philosophy & Limitations
-
No R-side validation:
- Schema validation and error handling is performed in the browser by SurveyJS itself.
-
Custom widgets/plugins:
- Official support for registering new question types from R is not included.
- Power users can inject JavaScript via
pre_render_hookand related arguments.
See the Advanced JS Hooks & Events vignette.
- Official support for registering new question types from R is not included.
-
File uploads, Survey Creator, PDF export:
- Not included, but see the vignettes and SurveyJS docs for guidance and alternatives.
Advanced: Custom JavaScript and Custom Widgets
- rsurveyjs allows you to inject any JavaScript code via
pre_render_hook,post_render_hook, andcomplete_hook.- Advanced users can use these hooks to register SurveyJS custom widgets or plugins, add event listeners, or extend survey logic—provided you are familiar with the SurveyJS JavaScript API.
- Note: There is currently no high-level R API for defining or registering new question types from R code alone.
Custom widget support is available for power users only, via JavaScript hooks.
- For real-world JS examples, see the Advanced JS Hooks & Events vignette.
Note on Custom JavaScript Hooks
Custom JavaScript hooks (pre_render_hook, post_render_hook, complete_hook) allow you to inject JavaScript code into the SurveyJS widget from R.
This is standard for trusted/internal use, but please be aware that any code supplied will be executed in the user’s browser.
If your app is public or multi-user, only use this feature for users you fully trust.
