help with a form : copy dropdown value to textbox value

[anarchoi]

Hi,

I have a form script with a dropdown box listing a lot of albums in this format:
"The Band - Name of the album"

there is another feild the users have to fill, it's a textbox where you have to write the band name. This is just making things harder for my members since the band name is already written in the album name, but filling the textbox is required for the process.

what i would like to do is the following:

When a user either click the submit button, or automaticaly when the dropdown box value is changed:
Automaticaly copy ONLY the text BEFORE the " - " from the dropdown to the textbox

Example:
If user select entry "abcdefg - hijklmnopqrstuvwxyz" from the dropdown, then:
Write "abcdefg" in the textbox

THANKS A LOOOT!

that's a javascript question. you should post it on a javascript forum. this is a php forum.

another possiblity is that you could restructure your form so they can choose the band name and then choose the album.

are you sure it's possible to pick the text before the " - " only with javascript?

i'm certain it's possible but I don't know the code. if you want php to do it, then you are going to have to set up your select box to refresh the page so that the appropriate php code can run. remember, php runs on the server not the client. in order to get php code to run, you have to request a page that contains code.

call this javascript function on click on the dropdown,

function copytext()
{
 var parts = document.getElementById('dropdownId').value.split('-');
 document.getElementById('textboxId').value = parts[0] ;
}
