Dynamically Update Option Value Menu Item

09-25-2001, 08:51 AM

Hi:

Is there a way to dynamically update an option value menu item? For example,

<option value="action" > Add </option>

change the color of "Add" so it appears grayed out to the user if they select a particular checkbox.

Thanks,

Koch

Hiya Koch.

Hmm. Thats a tricky one.

it would have to be JavaScript to do it live.

or you could use server-sdie script like php to chieve the effect, but that would only effect forms on the next page.

not sure if you could achieve this with JavaScript to be honest.

Which one r u after?

Hi Dean:

Thanks for the help. I had thought about JavaScript as well but wasn't sure how to do it. Sounds like the only way would be to update the option value menu item on the form on the next page.

Thanks,

Koch

Cool.

Okay, this is the jist of it.

Using a server-side language (i am going to use PHP as an example, as I familiar with it) we could pick up which options the user had submitted on the last page.

With PHP, you give a variable a name -

Code:

<input type="text" name="badger">

Then, in the PHP script that the form posts to, you have a new variable called $badger .

If your code says

echo $badger

It will write whatever the user posted in the form to the page.

Obviously, it can get more powerful than that, using 'if' statements and stuff.

Do you have knowledge of any server-side scripts?

If not, I recommend php.

goos resources for php -

http://www.php.net
http://www.phpbuilder.com
http://www.zend.com

Good Luck.

Thanks Dean. It sounds like php will do the trick for us.

Thanks again,
