Textarea background color change

**SiteShrine** · 02-22-2009 09:51 PM

I have a form that I have put together which needs the text area results to have either a font color change or a background color change based on the click of a radio button. I need to have 4 different color changes. Here is my current coding.
Thanks in advance,

Code:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script type="text/javascript">
function check(winddirection)
  {
  document.getElementById("forecast").value=winddirection;
  }



</script></head>

Questions:

1. Where is the <textarea> you wish to color change (or is it just the 'text' box)?
2. What are the colors you wish to change to and under what radio button conditions?

BTW: As an un-informed user, it might be nice to know what each cloud type looks like.
Possibly display small image of clouds when selected?

I NEED THE ON CLICK RESULT TO BE A DIFFERENT COLOR FOR EACH FOR A TOTAL OF 4 DIFFERENT COLORS
The blue text is where the text results will display.

Try this ...

Code:

function check(winddirection)  {
  document.getElementById("forecast").value=winddirection;
  var cloud_color = 'white';
  if (winddirection.indexOf('Excellent') == 0) { cloud_color = 'yellow'; }
  if (winddirection.indexOf('Very Good') == 0) { cloud_color = 'green'; }
  if (winddirection.indexOf('Good') == 0) { cloud_color = 'lightblue'; }
  if (winddirection.indexOf('Fair') == 0) { cloud_color = 'orange'; }
  document.getElementById('forecast').style.backgroundColor = cloud_color;
}

Change colors as needed ... could also be #rrggbb settings.
