PS: wangEditor can only understand the HTML format produced by editor.getHtml(), but custom HTML format.

If you want to insert some HTML, use dangerouslyInsertHtml please.

isEmpty

Determine whether the editor is empty (just has an empty paragraph)

editor.isEmpty()

TIP

This method can only identify an empty paragraph. If you want more info, use editor.getText() or editor.getHtml().

Node API

Please learn the editor content node structure standard first.

const nodeList = [node1, node2]

SlateTransforms.insertNodes(editor, nodeList)

import { SlateTransforms } from '@wangeditor-next/editor'

SlateTransforms.removeNodes(editor)

Get selected nodes

Use SlateEditor.nodes to get selected nodes, see Editor.nodes API in Slate.js doc.

import { SlateEditor, SlateElement, SlateNode } from '@wangeditor-next/editor'

const nodeEntries = SlateEditor.nodes(editor, {
    match: (node: SlateNode) => {  // TS syntax
    // match: (node) => {          // JS syntax
        if (SlateElement.isElement(node)) {
            if (node.type === 'paragraph') {
                return true // match paragraph
            }
        }
        return false
    },
    universal: true,
})

if (nodeEntries == null) {
    console.log('No selected paragraphs')
} else {
    for (let nodeEntry of nodeEntries) {
        const [node, path] = nodeEntry
        console.log('selected node', node)
        console.log('cur path', path)
    }
}

setNodes

Set node props in selection

import { SlateTransforms } from '@wangeditor-next/editor'

SlateTransforms.setNodes(editor, {
  // @ts-ignore
  textAlign: 'right'
}, {
  mode: 'highest'
})

getParentNode

const parentNode = editor.getParentNode(node) // return a node or null

Inline's concept, see Slate.js doc.

const inline = editor.isInline(node)

isVoid

Void's concept, See Slate.js doc.

const void = editor.isVoid(node)

isText

Text's concept, See Slate.js doc.

import { SlateText } from '@wangeditor-next/editor'

SlateText.isText(node) // true/false

isElement

Element's concept, See Slate.js doc.

import { SlateElement } from '@wangeditor-next/editor'

SlateElement.isElement(node) // true/false

addMark

Mark is text style, like bold italic...

editor.addMark('bold', true)
editor.addMark('color', '#999')

PS: This position is relative to editor DOM node, not <body>.
You can get editor DOM node's position by editor.getEditableContainer().getBoundingClientRect(), then compute position which is relative to <body>.

getNodePosition

Get selected node position data (like top left right bottom).

editor.getNodePosition(node) // eg. { left: "80.15px", top: "116px" }

PS: This position is relative to editor DOM node, not <body>.
