求荐SurveyJS、Form.io之外满足特定需求的开源JavaScript问卷构建库

Absolutely, there are several reliable open-source JavaScript survey-building libraries that check all your boxes. Since you’ve already looked at SurveyJS and Form.io, here are solid alternatives tailored to your needs:

1. JSON Forms #

• Multiple question types: Supports text inputs, radio buttons, checkboxes, rating scales, dropdowns, date pickers, and more—plus you can build custom components if needed.
• Conditional logic: Use schema dependencies and UI configuration rules to create dynamic branching (like showing a follow-up question only if a specific option is selected).
• JSON-based configuration: Fully driven by JSON Schema and UI Schema, making it easy to define, store, and modify survey structures programmatically.
• Documentation & maintenance: As an Eclipse Foundation project, it has comprehensive official docs, an active community, and consistent updates.
• Framework integration: Works with vanilla JavaScript, and offers official bindings for Angular, React, and Vue—so it fits right into your tech stack.

2. FormKit #

• Multiple question types: Comes with dozens of built-in controls (text, radio, checkbox, rating, file upload, etc.) and makes custom component creation straightforward.
• Conditional logic: Uses simple condition rules in your configuration to show/hide or enable/disable fields based on user input.
• JSON-based configuration: You can define surveys using either JSON Schema or FormKit’s own intuitive JSON syntax, supporting dynamic survey generation.
• Documentation & maintenance: Boasts detailed docs with tons of examples, an active community, and regular updates to add new features.
• Framework integration: Works with vanilla JavaScript, has deep Vue 3 integration, and can be adapted for Angular or React with a bit of custom wrapping.

3. Formily #

• Multiple question types: Covers all standard survey components (text, radio, checkbox, rating, cascading selects) and supports flexible custom component extensions.
• Conditional logic: Features a powerful expression engine to handle complex branching scenarios, like dynamic field validation or conditional rendering based on multiple inputs.
• JSON-based configuration: Supports both JSON Schema and its native JSON configuration format, letting you define surveys dynamically or load them from external sources.
• Documentation & maintenance: Has thorough official docs, an active community (backed by Alibaba), and ongoing updates to improve functionality.
• Framework integration: Offers first-class support for React and Vue, and can be used with vanilla JavaScript—Angular integration is possible via custom wrappers.

Each of these libraries is free, open-source, and aligns with your core requirements. You can choose based on your preferred framework and how much customization you need for your survey flows.
