Json schema configuration

The form is configured according to json schema, json schema attribute reference http://json-schema.org/draft-07/json-schema-validation.html.

You can use form generation and form preview function replaces the work of a part of the handwritten json schema.

Attributes

Since the properties of the json schema do not fully satisfy the generation of the form, some custom properties have been added. The custom property name convention begins with $.

• id: string: The id of the current attribute. The general convention begins with $root and is separated by /. For example, $root/key1/key2, the id and json key names must correspond. When type is object, you need to add /properties, for example:

  {
    "id": "$root",
    "type": "object",
    "properties": {
      "key": {
        "id": "$root/properties/key",
        "type": "string"
      }
    }
  }

  When type is array, items need to add /items, for example:

  {
    "id": "$root",
    "type": "array",
    "items": {
      "id": "$root/items",
      "type": "string"
    }
  }

type="number" or type="integer":

The component renders the numeric input box by default (InputNumber). Configuration properties:
