The purpose of this button is to make it easy to change the way my app
stores names. The old way was with a first and last name for the whole
family, with the sex and birthdays of all family members later. Now
I'm trying to connect the names and birthdays, so any person in the
family that has their name listed can come in. The easiest way I've
come up with to move to the new way is with is a button that will copy
the name to whatever person has their radio button selected when the
button is pressed.
my radio buttons return the id number of a person record to a variable
- @households.hoh. Rails is handling this fine.
I'll need to add to the update method to copy the new name for the hoh
if the radio button was changed.
var hoh_chosen = $$('input.hoh:checked'); - when I try this, nothing
is selected, even with a radio button checked
I've tried surrounding the radio_button call with a <div class="hoh">
and <div id="hoh"> with no luck.
<%= radio_button "household", "hoh", person.id %>
To me, it looks like I'm either not setting the class name correctly,
or not looking for them right. Please help.
