jQuery HTML truncator

jQuery (JavaScript) plugin to truncate HTML text with "more"/"less" links.

For example, you might see

Lorem ipsum do (…more)

Clicking "…more" shows

Lorem ipsum dolor sit amet. (less)

Clicking "less" goes back to the truncated text.

There is also a live example (or try the provided example.html locally).

Graceful HTML handling

While there are many JavaScript truncators, this one is unique in handling HTML gracefully. That means you can truncate an element containing paragraphs, links, other markup and HTML entities without strange results. You can also choose to omit any HTML in the truncated version of the text.

<b>a &amp; b</b> is considered to be 5 (not 16) characters long during truncation, and truncation will never cause start tags to be missing their end tags, entities or tags to be broken apart, and so on.

Usage

As shown in the provided example.html, just do e.g.

$(function() {
  $('.example').truncate({maxLength: 24});
});

The selector and options can, of course, be changed.

The available options are:

• more

  The text shown inside parentheses after the truncated text.

  Defaults to …more.

• less

  The text shown inside parentheses after the full text.

  Defaults to less. If set to false, it will be omitted.

• maxLength

  Defaults to 100.

  Note that the  (…more) bit counts towards the max length – so a max length of 10 would truncate 1234567890 to 12 (…more).

• linkClass

  The class name of more/less links. Defaults to nothing.

• stripFormatting

  Will strip HTML formatting in truncated text. Defaults to false.
