I want to get at the option value and the text within the options....i
have this:
var forms = $$(''select'');
forms.each(function(select, index) {
var opts = select.descendents;
})
i think it has something to do with descendents but i''m not sure.
Thanks :)

Why not just do something like this:
var options = $$("select option");
Which would give you a list of all the options in the page. If you
need to single out a specific select list, give it or its form an ID
attribute and use it to limit the returned elements from $$().
Alternatively, you could loop through the options array using
up("select") to determine the parent list for each option as
necessary.
Regardless, once you get the options, you can use their innerHTML
property to get at the text and the readAttribute() function to
extract their value. There could be a value property for option
elements, though, which would avoid the need to read the value
attribute, but I''m not sure on that one.

Aha i see. So my current code ( in normal javascript) works by getting
all the selects on a page and the iterates over them.
//this function finds all the selects and passes them by reference on
to selectReplacement()
function setForm() {
var s = document.getElementsByTagName(''select'');
for (var i=0; i<s.length; i++) {
selectReplacement(s[i]);
}
}
//this function does the swapping of selects for un-ordered lists
function selectReplacement(obj) {
var opts = obj.options;
for (var i=0; i<opts.length; i++) {
//and so on
What i wanted to do is for each of the selects get all the options
out....is there no way to do this even though i have a reference to
the select in ''select''......It seems a little verbose to get
all the
options out then find out which select they belong to..

Sure, you can do that. Here''s an example:
$$("select").each(function(list) {
var options = list.select("option");
...
});
In that example, you get all the select elements and, which are
referred to by the variable "list" within the anonymous function.
Then, the Prototype Element.select() function can be used to get all
of the options within each list.

Oh! one other thing: the Element.select() function is only available since Prototype 1.6.0. If you''re using an earlier version you''ll probably need to use the getElementsByTagName() function instead. - Dash - On Jan 24, 1:06 pm, dashifen <dashi...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Sure, you can do that.
