Selections in field dependant on selection in another field

purpleski · Jul 15, 2003

Hi

I have found the following script (see below my signature for full script) which I have adapted to do what I want it to. The options available in the field "Week" change dependant on the selection in field "Chalet".

So that selecting

<OPTION VALUE=1>Cret de la Neige
<OPTION VALUE=2>Dou du Pont
<OPTION VALUE=2>Iamato
<OPTION VALUE=2>Jolie
<OPTION VALUE=2>Olympie
<OPTION VALUE=2>Sapineaux

Gives weeks starting on a Saturday

Selecting <OPTION VALUE=2>Rousillion

gives weeks starting on a Sunday.

Is there a way of just having two arrays, one with Saturday weeks and one with Sunday weeks. Make the script neater and smaller.

If you are not sure what I mean please let me know.

Thanks to jerome.caron@globetrotter.net it is a great script in my opinion.

Thanks.

Purpleski

hi purpleski,

Do I read this correctly that options with the value 1 weeks start on saturday and options with the value 2 weeks start on sunday?

if that is the case it would be easy enough to check the value and apply the correct week to the second <select> box. If that is not the case you coul try:

Code:

<option value=&quot;1,1&quot;>

and use the second number for selecting the week to use.

just an idea. let me know if you need help making that work, or if you want a different idea.
