DraftJS: Import Element to ContentState

This is a module for DraftJS that will convert an HTML DOM Element to editor content.

It was extracted from React-RTE and placed into a separate module for more general use. Hopefully it can be helpful in your projects.

Installation

npm install --save draft-js-import-element

This project is still under development. If you want to help out, please open an issue to discuss or join us on Slack.

Usage

stateFromElement takes a DOM node element and returns a DraftJS ContentState.

import {stateFromElement} from 'draft-js-import-element';
const contentState = stateFromElement(element);

Options

You can optionally pass a second Object argument to stateFromElement with the following supported properties:

• customBlockFn: Function to specify block type/data based on HTML element. Example:

stateFromElement(element, {
  // Should return null/undefined or an object with optional: type (string); data (plain object)
  customBlockFn(element) {
    let {tagName, style} = element;
    if (tagName === 'ARTICLE') {
      return {type: 'custom-block-type'};
    }
    // Add support for <p style="text-align: center">...</p>
    if (tagName === 'P' && style.textAlign) {
      return {data: {textAlign: style.textAlign}};
    }
  }
});

• blockTypes: Deprecated; use customBlockFn.

stateFromElement(element, {
  blockTypes: {
    // support `<center>` as a custom block type `center-align`
    'center': 'center-align'
  }
});

• elementStyles: HTML element name as key, DraftJS style string as value. Example:

stateFromElement(element, {
  elementStyles: {
    // Support `<sup>` (superscript) inline element:
    'sup': 'SUPERSCRIPT'
  },
});
