but i can''t seem to find the answer after about 45 minutes of googling
and
API browsing
i have a select
<select id="list">
<option value="0">Please Choose One:</option>
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
</select>
how do i get the actual text?
$F(''list'') returns 0 through 4
$(''list'').value returns 0 through 4
$(''list'').selectedIndex returns 0 through 4
i just can''t seem to stumble upon the one that will give me the actual
text...
any help would be cool.
Thanks!

I cant speak for the other browsers but I think the actual property is innerText in ie... might be the same in others?> var list = $(''list''); > alert(list.options[list.selectedIndex].innerText); >Gareth On 8/30/07, Andrew Kaspick <akaspick-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > > var list = $(''list''); list.options[list.selectedIndex]; > > ? > > On 8/29/07, Brian Williams <brianw1975-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > but i can''t seem to find the answer after about 45 minutes of googling > and > > API browsing > > > > i have a select > > > > <select id="list"> > > <option value="0">Please Choose One:</option> > > <option value="1">one</option> > > <option value="2">two</option> > > <option value="3">three</option> > > <option value="4">four</option> > > </select> > > > > > > how do i get the actual text? > > > > $F(''list'') returns 0 through 4 > > $(''list'').value returns 0 through 4 > > $(''list'').selectedIndex returns 0 through 4 > > > > i just can''t seem to stumble upon the one that will give me the actual > > text... > > > > any help would be cool. > > > > Thanks! > > > > > > > > > > > > > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

it''s actually quite easy:
$$(''#hobbies option'').find(function(el){return
el.selected}).value; //
returns value of selected option

Okay...
The OP was actually about the option *text*, not the option *value*.
$F(''list'') should return the value(s) of the select
element''s
selected option(s). As does the following (the long way around):
$(''#hobbies option'').find(function(el){return
el.selected}).value;
list.options[list.selectedIndex]; // returns a reference to the
selected option.
The innerText option (which someone suggested) is an IE-only thing.
Won''t work on Mozilla, etc.
One thing to understand, is that if an option has no value attribute
defined, the value should default to the option''s text. (The example
problem provided had values specified, but you could leverage this
characteristic if needed.)
Use either the "text" attribute of the option object (preferred), or
innerHTML. There are a couple of ways of pulling this off. Here''s one:
$A($(''list'').options).findAll(function (o) {return
o.selected;}).pluck
(''text'');

For my applications, i generally use:
$(''list'').options[$(''list'').selectedIndex].text
and it works on all browsers

Yah, I forgot to add the .text in my response before. Wrote it from the top of my head... oops.

I use the following code to SET a select based upon value ...
Element.addMethods (''SELECT'', {
selectValue : function(element, s_Value) {
element = $(element);
element.selectedIndex =
$A(element.options).pluck(''value'').indexOf(s_Value);
return element;
}
}
);
With this, I can do
$(''selectID'').selectValue(''one'');
