    Posted: 25 January 2006 at 2:58pm
How do I get a textarea character counter to work on this tool via JavaScript?
 
I've tried several methods and nothing seems to work with this tool.
 
Any ideas?

It would probaly be very difficult as an Iframe is layed over the top of the original text area, coupled with HTML to format the text, I wouldn't have thought it would be very acurate.

is there a way onsubmit to have javascript count the values in the string prior to sending the form data for processing? if greater than 5 characters bounce back or let the page continue processing?
 
otherwise I guess I need to count the characters on the asp processing page.

You can do, using an onSubmit event that counts the value of the original textarea.

Sorry I am very pushed for time so don't have time to look into it for you,

Maybe someone else can help you, or have a look on Google for some JavaScript tutorials.

I've got several examples in Javascript that work fine outside this tool; since this tool lays an iframe on top it is tricky getting a counter to work. I'll have to play with it some more.
 
asp version:
strMessage1 = Request.Form("MessageText")
 lengthOfString = len(strMessage1) 'determine length of string
 If lengthOfString > 5 then 'if greater than 5 kick back to previous page with data
  response.redirect "message.asp?MF=" & strMessage1
 end if

Here is another attempt:
 
default.asp
<form name="myForm" id="myForm" method="post" action="display_form_submission.asp" onSubmit="textCounter(textarea,10)">
<textarea name="textarea" cols="80" rows="15" id="myTextarea" >
 

RTE_javascript.asp
'***********************************************
'***   JavaScript initialising RTE editor  *****
'***********************************************
%>
//character count
function textCounter(theField, maxlimit){if(theField.value.length == maxlimit) return false;}
 
I don't understand why this wouldn't work; any ideas?
