I have a text area box where users can describe a problem their having, but the problem is when the data is posted to my autoresponder, the autoresponder doesn't like hard carriage returns. Is it possible to keep all data entry on one line, so change something like this:

to this when the user submits:

I'm looking for some JS to do this. Does anyone have a JS script to handle this?

Hi, I think you are looking for something like this:

This goes into the <head> section:

<script language="javascript">
function nocr()
{
 with (document.form1)
 {
  for (var i=0; i < elements.length; i++)
  {
   if (elements[i].type == 'textarea')
   {
    elements[i].value=elements[i].value.replace(/\r\n/g,' ');
    elements[i].value=elements[i].value.replace(/\n/g,' ');
    alert(elements[i].value);
   }
  }
 }
}
</script>

Change the <form> tag into:
<form name="form1" onsubmit='nocr()'>

This will change newlines to a space for all the TEXTAREAs in the form.

The two replace might seem redundant, but the first one works with IE, the second works with Netscape (at least in a not too old Netscape)

hope this helps

My version is simmelar to frox's, except it is less hardcoded names:

<html>
<body>
<form>
<textarea name="UserInput" onChange="this.value=this.value.replace(/[\n\r]+/g,' ')">
</textarea>
<input type=submit>
</form>
</body>
</html>

Two notes: the onChange is always executed before submit. By onChange does the user also see the change on leaving the textarea for other elements input. If that confuses your user, then the same line can also be executed for all textareas in onSubmit, like frox did.
If you donot want the blanks for newlines, then add something else for your server side, for example a semicolon, a <br> or a special character.

My first guess was to use WRAP=SOFT
The description does state that browser is NOT sending the CR to server, but it seams not to be true.
Give that wrap also a try.
Like this:
<textarea name="UserInput" WRAP=SOFT>
</textarea>

Good luck,
Zvonko
