Univer Doc API

Concepts

Univer documents will provide users with the ability to layout documents at a professional level, with concepts that are as consistent as possible with Word.

Document

The command system unitId corresponds to the unique identifier of the document; documents do not have a subUnitId.

The text content of the document is stored in the body.dataStream string, which does not contain style information.

Style information is stored in a separate data structure and is associated with the text content by subscript indexes.

For elements such as line breaks, page breaks, sections, paragraphs, tables, etc., the text content is marked with different special characters that are converted to the corresponding element at rendering time.

Create Document

The univer.createUnit(UniverInstanceType.UNIVER_DOC, {}) method creates and returns a DocumentDataModel object.

In the following example, a blank document is created by passing in an empty object.

Get Document Id

const univerAPI = FUniver.newAPI(univer);
const activeDoc = univerAPI.getActiveDocument()
const unitId = activeDoc?.getId()

Get Document Data

const univerAPI = FUniver.newAPI(univer);
const activeDoucment = univerAPI.getActiveDocument()
const saveData = activeDoucment.getSnapshot();

Or

univer.createUnit(UniverInstanceType.UNIVER_DOC, {})
const saveData = document.save();

Destroying Document

When we no longer need the document, we can call the dispose method of the Univer instance to destroy the instance.

univer.dispose();

Text

Operate on text elements in rich text areas

Append Text

Adds the specified text to the end of this text region.

const univerAPI = FUniver.newAPI(univer)
const activeDoc = univerAPI.getActiveDocument()
activeDoc?.appendText('Univer')

Delete Text

Delete the character before the cursor

const univerAPI = FUniver.newAPI(univer)
univerAPI.executeCommand("doc.command.delete-left")

Delete the character after the cursor

const univerAPI = FUniver.newAPI(univer)
univerAPI.executeCommand("doc.command.delete-right")

Styles

Set the font color for the selected text

univerAPI.executeCommand("doc.command.set-inline-format-text-color", {value: "#ff0000"})

page break

\f is a page break, used to insert page breaks in a document.

const univerAPI = FUniver.newAPI(univer)
const activeDoc = univerAPI.getActiveDocument()
activeDoc?.appendText('\f')

List

Adds an unordered list to the paragraph where the cursor is located; repeated calls cancel the unordered list.

const univerAPI = FUniver.newAPI(univer)
univerAPI.executeCommand("doc.command.list-operation", {listType: 'BULLET_LIST'})

Adds an ordered list to the paragraph where the cursor is located; repeated calls cancel the ordered list.

const univerAPI = FUniver.newAPI(univer)
univerAPI.executeCommand("doc.command.list-operation", {listType: 'ORDER_LIST'})
