batchUpdatePageElements

static batchUpdatePageElements(
  deleteNumList: number[],
  elements: Element[],
  page: number,
  layer?: number | null
): Promise<APIResponse<boolean>>;

When this API operates on the current page, call getPageDisplaySize first to get the current page display size. Do not call PluginFileAPI.getPageSize to get the file page size, otherwise the position data may not match.

deleteNumList deletes by in-page index (numInPage) and doesn’t involve the cache. The elements part inserts new elements, typically from createElement or existing elements read from elsewhere; uuid stays the same before and after insertion, and this requires those elements to still be present in the native cache — elements that can’t be found in the cache are silently skipped instead of causing a separate error. See Element Caching and Release for details. Parameters

Parameter	Type	Description
`deleteNumList`	`number[]`	In-page element indices to delete, starting from `1`
`elements`	`Element[]`	New elements to insert
`page`	`number`	Page index, starting from `0`
`layer`	`number \| null`	Optional layer parameter. For note files (`.note`), when omitted, the current layer is used. For recognized notes, the parameter is ignored whether you pass it or not because recognized notes have only one layer. For document files (`.pdf`, `.epub`, etc.), the parameter is ignored whether you pass it or not because document files have only one layer. When provided, valid values are `0-3`

Returns

APIResponse<boolean>: result === true indicates the batch update succeeded

Throws

Throws a parameter validation error when deleteNumList is not a valid integer array
Throws a parameter validation error when elements is not a valid element array
Throws a parameter validation error when page is not an integer greater than or equal to 0
Throws a parameter validation error when layer is provided but is not an integer in the range 0-3

Example

import { PluginCommAPI, type Element } from 'sn-plugin-lib';

/**
 * Example: batch update elements on a specified page in the current file.
 */
export async function exampleBatchUpdatePageElements(elements: Element[]) {
  const deleteNumList = [1, 2];
  const page = 0;
  const layer = 0;
  const res = await PluginCommAPI.batchUpdatePageElements(deleteNumList, elements, page, layer);
  if (!res.success) {
    console.log('batchUpdatePageElements failed', res.error);
    throw new Error(res.error?.message ?? 'batchUpdatePageElements call failed');
  }
  console.log('batchUpdatePageElements result', res.result);
  return res.result;
}
