Good2Dou

A UserScript to simplify the process of adding new book subjects to Douban by automatically extracting and injecting metadata from Goodreads book detail pages.

Features

• Goodreads Metadata Extraction: Automatically parses hidden data on Goodreads book pages (using the __NEXT_DATA__ element) to extract:
  • Title and Subtitle
  • Author(s)
  • Description (cleaned up from HTML)
  • ISBN-13
  • Publisher and Publication Date (Year, Month, Day)
  • Number of Pages
  • Format (e.g., Paperback, Hardcover)
  • Cover Image URL
• Seamless Workflow: Provides an "Add to Douban" button on Goodreads to extract data and open the Douban "Add New Subject" page in a new tab.
• Autofill Forms: Provides context-aware buttons on Douban's new subject pages to automatically fill fields:
  • Page 1 (ISBN & Title): Fills initial Title and ISBN.
  • Page 2 (Autofill More): Fills Main Title, Subtitle, Author(s), Publisher, Publication Date, Pages, Format, and Description.
  • Page 3 (Download Cover): Uses GM_xmlhttpRequest to fetch and trigger a download of the cover image, bypassing potential CORS issues.
