selectSectionValidation$(): Observable<TSectionValidation>¶
The selectSectionValidation$ method allows to validate a current section containing additional fields and check for potential errors.
Returned value¶
A returned value has a type of Observable<TSectionValidation> where TSectionValidation represents an object that tells whether a section was successfully validated or not.
Example¶
In this example we make a basketAdditionalFieldsApi call to validate the basket section with additional fields.
useStorefront(async (storefront) => {
let basketAdditionalFieldsApi = storefront.getApiSync('basketAdditionalFieldsApi');
if (!basketAdditionalFieldsApi) {
const featureSystemApi = this.getApiSync('FeatureSystemApi');
await featureSystemApi.registerDynamic('basket');
basketAdditionalFieldsApi = storefront.getApiSync('basketAdditionalFieldsApi');
}
const validation$ = basketAdditionalFieldsApi.selectSectionValidation$();
validation$.subscribe((validation) => {
if (validation.isValid === false) {
// do something whenever the section is invalid
}
else {
// do something whenever the section is valid
}
})
});
