org.brutusin:json-forms is a javascript library that generates HTML forms from JSON Schemas.
I am currently not having time to maintain this project, so first of all my apologies if some issues have been unresponded. Branch v2 contains a completely new rearchitecture of the project, that I started several months ago but left unfinished. If someone is interested in continuing my work I will be happy to guide them
Table of Contents:
- Dynamic schemas support
- Extensible and customizable
- No external libraries needed
- Validation
- Multiple forms per document supported
Include the main library dependencies:
<link rel="stylesheet" href='dist/css/brutusin-json-forms.min.css'/>
<script src="dist/js/brutusin-json-forms.min.js"></script>Optionally, include the bootstrap extension (requires bootstrap):
<script src="dist/js/brutusin-json-forms-bootstrap.min.js"></script>Create the javascript BrutusinForms instance, schema being a javascript object representing the schema structure:
var schema = {"type": "boolean"}
var BrutusinForms = brutusin["json-forms"];
var bf = BrutusinForms.create(schema);And finally render the form inside a container with optional preloaded JSON initial data, data:
var container = document.getElementById('container');
bf.render(container, data);
This library supports dynamic schemas, that is, subschemas that can change depending on the value of other parts of the data.
This lets creating dynamic forms that vary their shape depending on the values entered by the user. This is extremely useful for big autogenerated schemas, that aggregates lots of subschemas and have functional bindings, given that it allows to show the user a simpler, non-error-prone form, also avoiding asking for unneeded data.
Dynamic schemas are built upon two main blocks:
- Custom (non-standard) schema property called
dependsOn, to build the subschemas dependency graph - Brutusin DSL for path expressions, for identifying subschemas.
