Delete all annotations
Q: We want to delete all annotations in the document at once.
A: There’s no specific command to delete all annotations. However, it can be easily achieved by iterating the pages, retrieving all its annotations and calling PSPDFKit.Instance#delete()
on their IDs:
PSPDFKit.load(configuration).then(instance => { (async () => { const pagesAnnotations = await Promise.all( Array.from({ length: instance.totalPageCount }).map((_, pageIndex) => instance.getAnnotations(pageIndex) ) ); const annotationIds = pagesAnnotations.flatMap(pageAnnotations => pageAnnotations.map(annotation => annotation.id).toArray() ); await instance.delete(annotationIds) })(); });
This has been tested with PSPDFKit for Web 2020.5.0
