描述

Expected behavior

We should track when changes are made to the form since the last save, and if the user is navigating away from the edit page while there are unsaved changes, prompt them to save or to confirm their navigation action.

Actual/Current behavior

Current behavior is that there is no check for unsaved changes. If the user accidentally navigates away from the edit page, then these changes are lost.

Steps to reproduce the actual/current behavior

  1. Select a post from the admin page to edit
  2. On the edit screen, make some changes to the post
  3. Navigate away from the edit screen without clicking the save button

At this point, if you view the selected post, the unsaved changes will be lost.

研究方向
Examine the admin UI code for editing posts, likely in a React component. Look for how navigation is handled (e.g., React Router) and implement a `beforeunload` event or a custom prompt. Check if there are existing hooks for form dirtiness (like `useState` with `isDirty`). Review similar features in the repo or linked resources. The maintainer has not provided additional guidance, so the contributor should start by reading the current form submission code path.
