This will trim the text (str) at the specified length (trimat) and then
delete everything AFTER the last space it finds. This way no words get cut
in half. This is a much scaled down version of what I use for 'teasers' to
articles. This method simply removes html rather than take them in to
account when trimming the length.
<cfscript>
function teaserText(str,trimat)
{
if(len(str) gt trimat)
{
// Remove any html tags so they arent counted in the length
str = rereplace(str, "<.*?>", "", "all");
//Cut the text at the desired length
str = left(str, trimat);
//Delete everything after the last space character
str = listdeleteat(str, listlen(str, " "), " ");
//Add '...' to the end to indicate that there is more to
//read than what you see here
str = str & "...";
}
return str;
}
</cfscript>
