Ellipsis.js

Ellipsis.js is a Pure Javascript Library to add some ellipsis on some complex DOM elements such as multiline divs or elements with childs (links, spans, etc.). The library is fully responsive, works across all major browsers, and try to be highly configurable. It is also very light, with a size of ~4kb when minified.

Demo:

https://glinford.github.io/ellipsis.js/

Installation:

Bower

bower install ellipsis.js

NPM

npm install ellipsis.js

Or…

git clone https://github.com/glinford/ellipsis.js

Usage:

<script src="/your/path/ellipsis.min.js"></script>
<script type="text/javascript">
  Ellipsis(); //default conf
</script>

By default Ellipsis.js will work on DOM elements that have a 'clamp' class and will add ellipsis after 2 lines.

Configuration properties:

{
  ellipsis: '…', //default ellipsis value
  debounce: 0, //if you want to chill out your memory usage on resizing
  responsive: true, //if you want the ellipsis to move with the window resizing
  className: '.clamp', //default class to apply the ellipsis
  lines: 2 //default number of lines when the ellipsis will appear
  portrait: null //default no change, put a number of lines if you want a different number of lines in portrait mode,
  break_word: true //default the ellipsis can truncate words
}

Lists:

debounce | Number | Default: 0 | Value in Milliseconds. If set to 0, it will use window.requestAnimationFrame (or a polyfill for IE <= 9) to debounce the resize events.
responsive | Boolean | Default: true | True is you want the ellipsis to be responsive, false if not.
className | String | Default: '.clamp' | A class or valid query selector where you want your ellipsis to appear
lines | Number | Default: 2 | The maximum number of lines before ellipsis
portrait | Number | Default: null | If you want a different number from the lines property on portrait mode.
break_word | Boolean | Default: true | If true the words can be truncated by the ellipsis, eg: "Hello Wo…", if false they won't, eg "Hello …"

"Manual" mode:

You can use the Ellipsis.js object to apply the configuration to additional DOM elements after it has been loaded:

var ellipsis = Ellipsis();
var elements = document.getElementsByClassName('.special-title');
ellipsis.add(elements);

This can be done with a single element:

ellipsis.add(elements[0]);

If using Ellipsis.js manually, you can disable the selector option in the configuration like this:

var ellipsisConf = {className: false};
var ellipsis = Ellipsis(ellipsisConf);

Known Issues:

By default the line-height property of a text is 'normal' which cannot be computed with getComputedStyle() method. If that occurs we will replace the line-height from normal to font-size + 2px which is the default value for most of browsers/OS.

The library does some heavy computation so it wont be suitable for pages that have like 100 elements with 100 lines each. I will work on optimization in future releases.

SVG text not supported.
