I am trying to load an array with wrapped lines from the text field. We are
feeding this into a function that takes the text and dynamically puts this in a
graphic via java.
Each element in the array will contain a line that is either wrapped or ended
by a cr/lf when the user hits enter at the end of the line
I populate a temp var with the 1st 34 characters of string. I look to see if
there are any of the above chr values...if not, then I back up until i find a
space and use that value as the EOL. Next line start at EOL +1 and I repeat
until I am out of string.
here's the string (and how it should be formatted):
Life is but a stopping place,
A pause in what's to be.
A resting place along the road,
To sweet eternity.
string temp for the first run:
Life is but a stopping place,A p
the return after all the processing is:
Life is but a stopping place,A
Here's the code...
<cfset txtLen=len(variables.text.string)>
<cfset arraylimit=0>
<cfset linelen=#arguments.char_count#>
<cfset startelem=1>
<cfset arrayelem=1>
<cfset lb = chr(13) & chr(10)>
<cfdump var="start loop"><br>
<cfdump var="#variables.text.string#"><br>
