I have a partial called people that has a radio button called hoh for
head of household. I'm trying to have JavaScript look at each person
and find the one that has hoh=1. This record then has it's name copied
to another field used for mailings. The web page has each record from
the partial with a different id, household_person_1001,
household_person_1030, etc. I can't see a way to get all the person
records into a JavaScript array. Please help.
Parts of this seem pretty easy, but there's one thing you didn't
mention -- where are the names stored? Are these radio buttons set up
with value="Bob Smith" or are they value="1030" (the ID)?
If you apply a classname to these radio buttons, then it's easy to
grab all of them.
var hoh_chosen = $$('input.hoh:checked');
Now you have all of the checked radio buttons with class="hoh" applied
to them. You iterate over them and find the nearby associated mailing
field:
hoh_chosen.each(function(elm){
// here I'm making another guess about your layout, that
// you've added a div around the common inputs for each person, and
// you've applied the classname mailing_name to that text field
var mailing = elm.up('div').down('input.mailing_name');
if(mailing){
mailing.setValue(elm.getValue());
// and that only works if the value of the radio is what you want
}
});
So lots of assumptions here, but it's really quite terse to do with
Prototype if the value is there to steal. But if your radio buttons
only have the ID, then I wouldn't set the mailing name here, but in
the controller after the form is submitted. There, you can look up the
user by the ID chosen in your hoh radio, and it's all there for you.
