Forms >>>
Converts carriage returns in a string to the tag so that the input can be properly displayed in HTML. Without the script, returns in an input field are not preserved when submitting in a form. Useful for guestbooks or other times when a user's input must be preserved.
Add the below code to the <body> section of your page:
<script
language="javascript"
type="text/javascript">
function
ConvertBR(input)
{
var
output =
"";
for
(var
i =
0;
i <
input.length;
i++)
{
if
((input.charCodeAt(i)
==
13)
||
(input.charCodeAt(i)
==
10))
{
i++;
output
+=
"<BR>";
}
else
{
output
+=
input.charAt(i);
}
}
return
output;
}
</script>
<form>
<textarea
name=message
rows=8
cols=50>You
may type a message here
Make sure to press the [Enter] key a few times.
That way you will be able to see the
conversion function in action.
</textarea>

<input
type=button

= ConvertBR(this.form.message.value);">
