<Form /> props

acceptcharset

The value of this prop will be passed to the accept-charset HTML attribute on the form.

action

The value of this prop will be passed to the action HTML attribute on the form.

Note that this just renders the action attribute in the HTML markup. There is no real network request being sent to this action on submit. Instead, react-jsonschema-form catches the submit event with event.preventDefault() and then calls the onSubmit function, where you could send a request programmatically with fetch or similar.

additionalMetaSchemas

This prop allows you to validate the form data against another JSON Schema meta schema, for example, JSON Schema draft-04. See Validation for more information.

ArrayFieldTemplate

React component used to customize how alls arrays are rendered on the form. See Custom Templates for more information.

autoComplete

The value of this prop will be passed to the autocomplete HTML attribute on the form.

autocomplete

Deprecated, same functionality as autoComplete

className

The value of this prop will be passed to the class HTML attribute on the form.

children

You can provide custom buttons to your form via the Form component's children. Otherwise a default submit button will be rendered.

const schema = {
  type: "string"
};

render((
  <Form schema={schema}>
    <div>
      <button type="submit">Submit</button>
      <button type="button">Cancel</button>
    </div>
  </Form>
), document.getElementById("app"));

Warning: There needs to be a button or an input with type="submit" to trigger the form submission (and then the form validation).

customFormats

This prop allows you to define custom formats for validation. See Validation for more information.

disabled

It's possible to disable the whole form by setting the disabled prop. The disabled prop is then forwarded down to each field of the form.

const schema = {
  type: "string"
};

render((
  <Form schema={schema}
        disabled />
), document.getElementById("app"));

If you just want to disable some of the fields, see the ui:disabled parameter in uiSchema.

enctype

The value of this prop will be passed to the enctype HTML attribute on the form.

extraErrors

This prop allows passing in custom errors that are augmented with the existing JSON Schema errors on the form; it can be used to implement asynchronous validation. See Validation for more information.

ErrorList

You can pass a React component to this prop to customize how form errors are displayed. See Validation for more information.

fields

Dictionary of registered fields in the form. See Custom Widgets and Fields for more information.

FieldTemplate

React component used to customize each field of the form. See Custom Templates for more information.

formContext

You can provide a formContext object to the Form, which is passed down to all fields and widgets. Useful for implementing context aware fields and widgets.

formData

Often you'll want to prefill a form with existing data; this is done by passing a formData prop object matching the schema.

id

The value of this prop will be passed to the id HTML attribute on the form.

idPrefix

To avoid collisions with existing ids in the DOM, it is possible to change the prefix used for ids (the default is root).

const schema = {
  type: "string"
};

render((
  <Form schema={schema}
        idPrefix={"rjsf_prefix"}/>
), document.getElementById("app"));

This will render <input id="rjsf_prefix_key"> instead of <input id="root_key">

liveOmit

If omitExtraData and liveOmit are both set to true, then extra form data values that are not in any form field will be removed whenever onChange is called. Set to false by default.

liveValidate

If set to true, the form will perform validation and show any validation errors whenever the form data is changed, rather than just on submit.

method

The value of this prop will be passed to the method HTML attribute on the form.

name

The value of this prop will be passed to the name HTML attribute on the form.

noHtml5Validate

If set to true, turns off HTML5 validation on the form. Set to false on default.

noValidate

If set to true, turns off all validation. Set to false by default.

ObjectFieldTemplate

React component used to customize how all objects are rendered in the form. See Custom Templates for more information.

omitExtraData

If set to true, then extra form data values that are not in any form field will be removed whenever onSubmit is called. Set to false by default.

onBlur

Sometimes you may want to trigger events or modify external state when a field has been touched, so you can pass an onBlur handler, which will receive the id of the input that was blurred and the field value.

onChange

If you plan on being notified every time the form data are updated, you can pass an onChange handler, which will receive the same args as onSubmit any time a value is updated in the form.

onError

To react when submitted form data are invalid, pass an onError handler. It will be passed the list of encountered errors:

const schema = {
  type: "string"
};
const onError = (errors) => console.log("I have", errors.length, "errors to fix");

render((
  <Form schema={schema}
        onError={onError} />
), document.getElementById("app"));

onFocus

Sometimes you may want to trigger events or modify external state when a field has been focused, so you can pass an onFocus handler, which will receive the id of the input that is focused and the field value.

onSubmit

You can pass a function as the onSubmit prop of your Form component to listen to when the form is submitted and its data are valid. It will be passed a result object having a formData attribute, which is the valid form data you're usually after. The original event will also be passed as a second parameter:

const schema = {
  type: "string"
};
const onSubmit = ({formData}, e) => console.log("Data submitted: ",  formData);

render((
  <Form schema={schema}
        onSubmit={onSubmit} />
), document.getElementById("app"));

Note: If there are fields in the formData that are not represented in the schema, they will be retained by default. If you would like to remove those extra values on form submission, you may need to set the omitExtraData and/or liveOmit props.

schema

Form schema. We support JSON schema draft-07 by default. See [Schema Reference]((https://json-schema.org/draft-07/json-schema-release-notes.html) for more information.

showErrorList

When this prop is set to true, a list of errors (or the custom error list defined in the ErrorList) will also show. When set to false, only inline input validation errors will be shown. Set to true by default. See Validation for more information.

tagName

It's possible to change the default form tag name to a different HTML tag, which can be helpful if you are nesting forms. However, native browser form behaviour, such as submitting when the Enter key is pressed, may no longer work.

<Form
  tagName="div"
/>

You can also provide a class/function component.

const CustomForm = props => <form {...props} style={...} className={...} />
// ...
<Form
  tagName={CustomForm}
/>

target

The value of this prop will be passed to the target HTML attribute on the form.

transformErrors

A function can be passed to this prop in order to make modifications to the default errors resulting from JSON Schema validation. See Validation for more information.

uiSchema

Form uiSchema. See uiSchema Reference for more information.

validate

The validate prop requires a function that specifies custom validation rules for the form. See Validation for more information.

widgets

Dictionary of registered widgets in the form. See Custom Widgets and Fields for more information.
