React-dotdotdot

Cross-browser multiline text ellipsis for react

Inspired by: https://github.com/BeSite/jQuery.dotdotdot

Internally uses: https://www.npmjs.com/package/clamp-js

Installation

npm install --save react-dotdotdot

Sample usage

import React from 'react'
import Dotdotdot from 'react-dotdotdot'

...

render() {
	return (
		<div>
			<Dotdotdot clamp={3}>
				<p>
					Long, long <br />
					content,<br />
					3 lines <br />
					will be shown.
				</p>
			</Dotdotdot>
		</div>
	)
}

Dotdotdot props:

clamp (Number | String | 'auto'). This controls where and when to clamp the text of an element. Submitting a number controls the number of lines that should be displayed. Second, you can submit a CSS value (in px or em) that controls the height of the element as a String. Finally, you can submit the word 'auto' as a string. Auto will try to fill up the available space with the content and then automatically clamp once content no longer fits. This last option should only be set if a static height is being set on the element elsewhere (such as through CSS) otherwise no clamping will be done.

useNativeClamp: [default: false] Use -webkit-line-clamp available in Webkit (Chrome, Safari) only.

splitOnChars: [default: ['.', '-', '–', '—', ' ']] Split on sentences (periods), hypens, en-dashes, em-dashes, and words (spaces).

animate: [default: false] animated clamp

truncationChar: The character to insert at the end of the HTML element after truncation is performed. This defaults to an ellipsis (…). useNativeClamp overrides it to default.

truncationHTML: String of HTML to use instead of truncationChar

tagName: [default: div] (String). The type of HTML tag which will wrap the component's content.

Notes

React-dotdotdot is simple plugin, if you need more functionality, consider using react-truncate https://www.npmjs.com/package/react-truncate

Known issues:

• react-dotdotdot does not work with text containers with nested markup.
• padding-bottom CSS rule breaks clamp
• line-height units might be important for React-dotdotdot. We recommend px over em
