data-*
props
The component forwards all data
attribute props. It further adds a -${language}
suffix to the values of the data-test
and data-track-component
attributes, e.g data-test="foo"
will get added to the input for en
as data-test="foo-en"
.
Main Functions and use cases are:
- Receiving localized input from user
Static Properties
createLocalizedString(languages, existingTranslations)
This function creates a localized string. It merges the languages
and the language keys of existing translations to form a localized string holding all languages.
The existingTranslations
argument is optional. If it is not passed, an empty localized field will be created.
const languages = ['en', 'de'];
LocalizedMultilineTextInput.createLocalizedString(languages);
// -> { en: '', de: '' }
In case existingTranslations is passed, it will merge an empty localized field with the existing translations. Usually this is used to ensure that a localized string contains at least the project's languages.
const languages = ['en', 'de'];
const existingTranslations = { en: 'Tree', ar: 'شجرة' };
LocalizedMultilineTextInput.createLocalizedString(
languages,
existingTranslations
);
// -> { en: 'Tree', de: '', ar: 'شجرة' }
isEmpty(localizedField)
Returns true
when all values in a localized field are empty.
LocalizedMultilineTextInput.isEmpty({});
// -> true
LocalizedMultilineTextInput.isEmpty({ en: '', de: ' ' });
// -> true
LocalizedMultilineTextInput.isEmpty({ en: 'Tree', de: '' });
// -> false
omitEmptyTranslations(localizedField)
Omits translations with empty values.
LocalizedMultilineTextInput.omitEmptyTranslations({ en: '', de: ' ' });
// -> {}
LocalizedMultilineTextInput.omitEmptyTranslations({ en: 'Tree', de: '' });
// -> { en: 'Tree' }
isTouched(touched)
Expects to be called with an object or undefined
.
Returns true
when at least one value is truthy.
RequiredValueErrorMessage
This field exports a default error message which can be used when the field is required, but the user provided no value. You can use it as
render (
return (
<div>
<LocalizedMultilineTextInput hasError={isMissing} />
{
isMissing && <LocalizedMultilineTextInput.RequiredValueErrorMessage />
}
</div>
)
)
