This is a function I use. You can take out the "..." part if not needed.
<cffunction name="trimLength" output="FALSE"
hint="Returns a string trimmed to the specified length plus
...">
<cfargument name="val" required="FALSE" default="" hint="string
to trim">
<cfargument name="len" required="FALSE" default="0"
hint="length to trim string">
<cfset var lst = 0>
<cfif len(ARGUMENTS.val) LE ARGUMENTS.len>
<cfreturn ARGUMENTS.val>
<cfelse>
<cfset lst = find(" ",ARGUMENTS.val,ARGUMENTS.len)>
<cfif lst IS 0>
<cfset lst = ARGUMENTS.len>
</cfif>
<cfreturn "#left(ARGUMENTS.val,lst)# ...">
</cfif>
<cfreturn ARGUMENTS.val>
</cffunction>

Subject: [DFW CFUG] trimming a string to so many words
Looking for a suggested resource where I might find how to trim a string to a
certain length, but not chop the words..
such that it would be say 250characters, but then go back to the last space.
I was thinking of just a rtrim, but wasn't sure if there was a better way?
Thanks
Colin
