Modify textbox

[rwt]

Hello,
I have no knowlege of javascript whatsoever so don't laugh at me please.
From a selection menu, I want people to be able to change a part of the text in the textbox bellow. How can I do that?

Here are my forms:
[HTML]<form method="POST" action="">
<select size="1" name="D1">
<option value="">linkone.com</option>
<option value="">linktwo.com</option>
<option value="">linkthree.com</option>
</select><input type="submit" value="Submit" name="B1"></p>
</form>
<form method="POST" action="">
<p><textarea rows="9" name="S1" cols="44"></textarea><input type="reset" value="Reset" name="B2"></p>
</form>[/HTML]

<form method="POST" action="">
<select size="1" name="D1" onchange="document.getElementById('look').innerHTML = this.value;">
    <option value="linkone.com">linkone.com</option>
    <option value="linktwo.com">linktwo.com</option>
    <option value="linkthree.com">linkthree.com</option>
    </select><input type="submit" value="Submit" name="B1"></p>
</form>
<form method="POST" action="">
    <p><textarea rows="9" name="S1" cols="44" id="look"></textarea><input type="reset" value="Reset" name="B2"></p>
</form>
 

Heres a simple way of doing it

I just have a question. Your code works fine, except in cases like follows:

For example: A merchant is trying to send out canned message email like:

$form .= "<option value=\"$shipping_today\">Shipping Today</option>";
$form .= "<option value=\"$shipping_soon\">Shipping Soon</option>";
$form .= "<option value=\"$shipping_drop\">Drop Shipping</option>";

Assume that the variables $shipping_today, $shipping_soon, and $shipping_drop don't have any HTML tags in them, the code would work fine. But if there are any HTML tags like <BR> or <P>, the code would give java runtime error.

I was wondering if there is any other method that would allow this. Basically, I am trying to use this solution to send out canned HTML messages. The box would change based on the selection chosen in the dropdown. Without any HTML tags in the variable, the message would be a single blob.

Thanks in advance...
