3. Add JS and init

🕹️ Usage

Init JS

// target all read more elements with `js-read-smore` class
const readMores = document.querySelectorAll('.js-read-smore')

// Init
ReadSmore(readMores).init()

Example by max word count

To truncate content by max word count, use the data attribute data-read-smore-words="" with desired value.

<div
  class="js-read-smore"
  data-read-smore-words="70"
>
  <p>Stuff and words and stuff and words.</p>
  <p>Words and stuff and words and stuff.</p>
  <!-- more HTML content -->
</div>

Example by max character count

To truncate content by max character count, use the data attribute data-read-smore-chars="" with desired value.

<div
  class="js-read-smore"
  data-read-smore-chars="150"
>
  <p>Stuff and words and stuff and words.</p>
  <p>Words and stuff and words and stuff.</p>
  <!-- more HTML content -->
</div>

Example defining read more/less text via data attribute

To truncate content by max character count, use the data attribute data-read-smore-chars="" with desired value.

<div
  class="js-read-smore"
  data-read-smore-chars="150"
  data-read-smore-more-text="Read Schmore"
  data-read-smore-less-text="Read Schless"
>
  <p>Stuff and words and stuff and words.</p>
  <p>Words and stuff and words and stuff.</p>
  <!-- more HTML content -->
</div>

Provide Options

ReadSmore supports a few options, such as editing the more/less text. See Options table below for more.

import ReadSmore from 'read-smore'

const readMores = document.querySelectorAll('.js-read-smore')

const options = {
  blockClassName: 'read-more',
  moreText: 'Peep more',
  lessText: 'Peep less'
}

// Pass in options param
ReadSmore(readMores, options).init()

Inline Read More link

You can have the Read More link appear inline with the ellipsed content, as opposed to below it.

Note: As of v2.2.0, required css dep was removed in favor of a pure js approach that simply applied inline styles.

1: Via data-read-smore-inline

<div
  class="js-read-smore"
  data-read-smore-chars="150"
  data-read-smore-inline="true"
>
  <p>Stuff and words and stuff and words.</p>
  <p>Words and stuff and words and stuff.</p>
  <!-- more HTML content -->
</div>

2: Via Option (effects all readSmore instances

const readMores = document.querySelectorAll('.js-read-smore')

const options = {
  isInline: true
}

const RMs = ReadSmore(readMores, options)

📓 Notes

Need to figure out how to handle ReadMore instances with ajaxed/Fetched in content, since the word count on existing instances will be already truncated.
Thinking the solution is to destroy and rebuild via a click event. Or, at least open all and rebuild on click.
