Shorten text without splitting words or breaking html tags

Question

I am trying to cut off text after 236 chars without cutting words in half and preserving html tags. This is what I am using right now:

$shortdesc = $_helper-         


        

Answer 1

Here is JS solution: trim-html

The idea is to split HTML string in that way to have an array with elements being html tag(open or closed) or just string.

var arr = html.replace(//g, ">\n")
              .replace(/\n\n/g, "\n")
              .replace(/^\n/g, "")
              .replace(/\n$/g, "")
              .split("\n");

Than we can iterate through array and count characters.
