select box

I have limited knowledge of Javascript. That is the main reason I am here.

I have a select box with all the states in it. When they click on California, a tax needs to be added. This would be easy if the tax was going to a normal form element, but it isn't. I need it to go to a hidden element.

Is there much difference? Any help would be greatly appreciated.

Thanks!

if you're talking about just carrynig the value which i'm assuming you are - i'm thinkin (not js) that you could just have the state names selected normally, and then do a comparison to an array in the form that collects the data.. if the state is california, then the tax is so much..

but if you're talking like, as soon as they select the state that the tax is automatically added right in front of their eyes - then you could just use the same concept as in using smilies only alter it to suit your form.. example: instead of onclick use onselect or something.

In the past I have used a code (in my case postage addon) as part of the value on the select. so it might be "CAA" where the first 2 chars are the actual state and the "A" is the tax percentage and I know that "A" is 10%, say.

Then I have my tax % array on the page on in a linked .js file. When the select's onchange event fires I get the new value, strip out the first 2 chars and have my tax code, I then populate my hidden field.

Accessing a hidden field is the same as for a normal text field - only you can't visually confirm the change.
