A package to enhance your developing experience with selection, using the Selection API and Range API.

The latest source code and releases are on GitHub.

WARNING: This package is under heavy development, the APIs may be changed in the future!

The developing branch is dev

Any contribution would be appreciate <3

I specially need support on unit testing to make the API as stable as possible!

• defineSelectable attach neccessary attributes to the element, got checked and called by default in some others APIs
• getSelection get the selection from the 2 sub APIs
  • getSelectionInputOrTextarea get the selection text, start, end and select direction
  • getSelectionContenteditable get the selection HTML, start, end, select direction is not supported
• getSelectionRect get the coresponding pixel-position of the selection by getting their bouding rects
• setSelection set the selection by using the 3 sub APIs
  • setSelectionNode
  • setSelectionInputOrTextareaElement
  • setSelectionContenteditableElement
• setHighlight create an underline by using the bounding boxes from getSelectionRect
• removeSelectionContent remove the selected content
• replaceSelectionContent replace the selected content with a new content
• attachFloating attach a floating tooltip to the selection bounding box
• keepSelection keep the selection from being deselected, helpful for interacting with Google Translate or Grammarly-like feature
• watchSelection watch the selection change and provide a callback hook for event handling

npm i @selectjs/core

# Or with pnpm
pnpm add @selectjs/core

Select any editable elements, input, textarea or element with contenteditable attribute from character to character using start and end options.

import { setSelection } from "@selectjs/core"

const element = document.querySelector('input')
// const element = document.querySelector('textarea')
// const element = document.querySelector('[contenteditable]')

setSelection(element, { start: 0, end: 5 })

Get the current selection information of the selected element.

import { getSelection } from "@selectjs/core"

const element = document.querySelector('input')
// const element = document.querySelector('textarea')
// const element = document.querySelector('[contenteditable]')

const result = getSelection(element)
