Common scenario: you want to show the first part of a long chunk of text, and then have the full text available via a link like " (more...) " , which would either show the text with javascript (more on that later) or take you to another page to see the full article.

For a long time now I have used the "fullLeft()" udf, which works just fine and does exactly what it should.  But the other day, I got a wild hair and, rather than calling in the fullLeft function to my page, decided to script something right in place... just 'because'.

And whaddyaknow, it works... works great, really.
But it is so simple - what am I missing?

Like most things, my 'aha' is haunted by a 'what if', as in 'what if it breaks on certain characters or other stuff in the text'?  What if I don't really know what the heck I am doing? But ...hey... it works!

//// Here is the logic:

take a chunk of text and a number, passed in as variables.

replace all line breaks in the text with <br> tags (easy to remove if not needed)

if the length of the text is more than the given number, cut it off at that
number of characters

find the number of characters at the end of the remaining string that come after the last space ( ' '), and remove them

if the text was trimmed, output the text in a p tag with a (more...) link  - this can all be modified to give the link a url, or in my case to use javascript to show the full text in place of the truncated content.

/// Here is the code:

 * Another version of "full left"
 * @param trimlength      Length, in characters, to trim text to (Required)
 * @param rawtext           Text to trim (Required)
 * @return Returns a string with an ellipsis (...)

// this line replaced line returns in the text block with html breaks
   rawtext = replace(rawtext, chr(13), '<br />', 'all');
      if (len(rawtext) gt trimlength)
   cuttext = left(rawtext, trimlength);
   trimlen = len(cuttext) - len(listLast(cutText, ' '));
   texttouse = left(rawtext, trimlen) & '... <em>(<a class="morelink" href="##">more</a>)</em>';
   texttouse = rawtext;
   textoutput = '<p>' & texttouse & '</p>';
   return textoutput;
