abbreviate(string, len)

Last updated September 6, 2005



Version: 3 | Requires: CF5 | Library: StrLib

Similar to the MaxLength UDF, but designed for outputting abbreviated lengths of HTML code (e.g. in list tables). Strips all tags, and makes sure any abbreviation is done to the last space within the given length. Also appends a properly escaped ellipsis character to the returned string.

Return Values:
Returns a string.


#abbreviate("<p>This bit of HTML copy is going to get <em>real</em> chopped up!</p>", 40)#


Name Description Required
string String to use. Yes
