🗃ī¸ Properties​

🏷ī¸ attachments​

Specifies the attachments handler used by blocks that support file uploads. If your form does not need file upload support, you can omit this property.

Type​

[IClassicController | undefined]

Example​

import { ClassicRunner, IClassicController } from "tripetto-runner-classic";
import ReactDOM from "react-dom";

// Create a new l10n namespace for the runner
const l10nNamespace = L10n.Namespace.create(namespace);

// Do stuff with it, like loading translations
l10nNamespace.load(/* Translation data here */);

// Use the gettext functions to retrieve translations
l10nNamespace._("Text to be translated");
l10nNamespace._n("1 car", "%1 cars", 10);

tip

If you only need updates on data changes, use the onData event.

Signature​

(instance: Instance) => void

Parameters​

NameTypeOptionalDescription
instanceInstanceNoReference to the runner instance.

🔔 onComplete​

Specifies a function that is invoked when the runner is completed (after the data is submitted).

tip

Have a look at the Collecting response data guide to learn how to feed an identifier or reference associated with the submitted response data back to the runner.

Signature​

(instance: Instance, id?: string) => void

Parameters​

NameTypeOptionalDescription
instanceInstanceNoReference to the runner instance.
idstringYesContains an optional identifier or reference returned by the server.

🔔 onData​

Parameters​

NameTypeOptionalDescription
instanceInstanceNoReference to the runner instance.

🔔 onDestroy​

Specifies a function that is invoked when the component unmounts.

Signature​

() => void

🔔 onEdit​

Specifies a function that is invoked when an edit action is requested. This event is useful in a live preview setup where the builder can open the properties panel of the referenced item.

tip

Read the Live form preview guide for an example.

Signature​

(type: "prologue" | "epilogue" | "styles" | "l10n" | "block", id?: string) => void

Parameters​

NameTypeOptionalDescription
type"prologue" | "epilogue" | "styles" | "l10n" | "block"NoSpecifies the type of item being edited.
idstringYesSpecifies the item identifier.

🔔 onImport​

Specifies a function that is invoked when data can be imported into the instance. To import form data, you need to use one of the Import functions from the Runner Foundation package as shown in the Prefilling forms guide.

tip

Have a look at the Prefilling forms guide to learn more about importing data.

Signature​

(instance: Instance) => void

Parameters​

NameTypeOptionalDescription
instanceInstanceNoReference to the runner instance.

🔔 onL10n​

Specifies a function that is invoked when the runner needs a locale or translation. This event is useful for dynamic loading of locale information and translations.

tip

Have a look at the Localization guide to learn how to use this event.

Signature​

(l10n: IL10n) => Promise<void>

Parameters​

NameTypeOptionalDescription
l10nIL10nNoReference to the l10n object.

Return value​

Returns a Promise that resolves when the loading is completed.

🔔 onPause​

Specifies a function or recipe that is invoked when the runner wants to pause. The recipe email can be used if you want to collect the email address of the respondent before pausing the form. Read the Pause and resume guide for more information about this feature.

Once you implement the onPause event, a pause button will appear in the runner's UI. When the respondent clicks this button, the pause event fires. When the email recipe is used, the runner will first ask for the respondent's email address and then invoke the event.

tip

Have a look at the Pause and resume guide to learn more about this feature.

Signature​

{
    recipe: "email";
    onPause: (
      emailAddress: string,
      snapshot: ISnapshot,
      language: string,
      locale: string,
      namespace: string
    ) => Promise<void> | boolean | void;
  } | ((snapshot: ISnapshot, language: string, locale: string, namespace: string) => Promise<void> | boolean | void)

Parameters​

NameTypeOptionalDescription
emailAddressstringNoContains the email address when the email recipe is used.
snapshotISnapshotNoContains the snapshot data.
languagestringNoContains the language used in the runner (default is en).
localestringNoContains the locale identifier used in the runner (default is en).
namespacestringNoContains the namespace identifier for the runner.

Return value​

Returns true when the pause succeeded, false if it failed or a Promise that resolves in case the pause succeeded or rejects in case of an error.

🔔 onReady​

Specifies a function that is invoked when the runner is ready.

info

The onReady event is invoked after all the resources (form definition, styles, locales, and translations) are loaded.

Signature​

(instance: Instance | undefined) => void

Parameters​

NameTypeOptionalDescription
instanceInstance | undefinedNoReference to the runner instance or undefined if no form has started.

🔔 onReload​

Specifies a function that is invoked when the runner wants to reload the definition. The definition returned by this event handler is loaded, preserving the data already entered by the user.

info

This event will be automatically invoked when data is submitted to an endpoint, but the endpoint indicates the form is outdated. To indicate this, the onSubmit event can reject with status outdated. See the Collecting response data guide for more information about this feature.

Signature​

() => IDefinition | Promise<IDefinition>

Return value​

Returns the reloaded IDefinition or a Promise that resolves with the IDefinition.

🔔 onSubmit​

Specifies a function that is invoked when the runner submits data. This event is the one to use to submit the form data to an endpoint. To retrieve the form data, you need to use one of the Export functions from the Runner Foundation package as shown in the Collecting response data guide.

This event supports different return types. First of all, you can return a boolean value to indicate if the submission was successful or not. That's only useful for synchronous operations. If you need async operation, you can return a Promise which resolves in case of a successful operation or rejects when the submission fails.

tip

Have a look at the Collecting response data guide to learn more about submitting data, async operation, and handling errors. To learn more about validating the response data, read the Validating response data guide. If you need spam protection for your forms, the Prevent form spamming guide is of interest to you.

  Promise<string | undefined> | boolean | void
NameTypeOptionalDescription
instanceInstanceNoReference to the runner instance.
languagestringNoContains the language used in the runner (default is en).
localestringNoContains the locale identifier used in the runner (default is en).
namespacestringNoContains the namespace identifier for the runner.

Return value​

Returns true when the submission succeeded, false if it failed or a Promise that resolves with an optional reference string (in case it succeeds) or rejects (in case of an error).

🔔 onTouch​

Specifies a function that is invoked when the runner is "touched" by a user. This is an interaction by the user with the runner by either the mouse, touch input, or keyboard.

Signature​

() => void
