It seems I have this working using the approach of rendering all of the
partials and then hiding/displaying the div as needed. I was able to
get this to partially work in the past with an RJS file using Marnen's
suggestion of using a separate form builder within each of the partials.
This was done to address the fact that I couldn't pass the form object
through the observe_field method.
Unfortunately, with this current approach I have the same issue I had
when I got it working with the RJS file. This remaining issue is that
when a validation error occurs, teh partial is getting cleared. I'm not
sure why. If I do a simple reload/refresh on the browser, the values
within the partials are preserved, but not when a validation error
occurs.
Any thoughts on what the validation may be doing that clears the dynamic
partial? Do you think the validation errors cause a re-rendering of the
partials even though a page reload/refresh does not?
here is some of the code...
==============Form the main form page .html.erb =============
.
.
.
<div id="partial1" style="display: none;">
<%= render "partial1" %>
</div>
<div id="partial2" style="display: none;">
<%= render "partial2" %>
</div>
<div id="partial3" style="display: none;">
<%= render 'partial3', :w => f %>
</div>
<%= javascript_tag "set_section_two();" %>
===== application .js file ================
function set_section_two() {
var team=document.getElementById("trial_org_id").value;
hide_all_dynamic_divs()
//alert('set_section_two() called');
switch(team)
{
case '1':
$('partial1').style.display = 'block';
break;
case '2':
$('partial2').style.display = 'block';
break;
case '3':
$('partial3').style.display = 'block';
break;
default:
// alert('other');
break;
}
}
function hide_all_dynamic_divs(){
$('partial1').style.display = 'none';
$('partial2').style.display = 'none';
$('partial3').style.display = 'none';
}
