pass javascript variable to erb code for checking condition

[Sai Ch]

controller/course_controller.rb:
def edit
@course = Course.includes(holes:
:beacons).find(params[:id])
end

views/course/edit.html.erb


<%= form_for (@course), remote: true do |cb| %>

<%= cb.text_field :course_name, class: “name" %>

<div id="holes">
<% (cb.object.holes).each do |i| %>
<a href=“#" id="hole-<%= i.id %>" class="holeid"
value="<%= i.id %>"><%= i.id %> </a>
<div class="circular circle-green circle-left"></div>
<% end %>
</div>

<%= cb.fields_for :holes do |hb| %>
<% if (hb.object.id) == (cb.object.holes.first.id) %>

<h3> <%= "#{hb.object.id} - #{hb.object.name} " %></h3>

<%= hb.fields_for :beacons do |bb| %>
<div class=“tip"> <%= bb.label :CaddyTip %></div>
<div class=“ctip"> <%= bb.text_area :caddy_tip
%></div>

<div class=“shot"> <%= bb.label :BestShot %></div>
<div class=“bshot"> <%= bb.text_area :best_shot
%></div>

<div class=“be"> <%= bb.label :Be_Aware %></div>
<div class=“beaware"> <%= bb.text_area :be_aware
%></div>

<% end %>#beacons form close

<% end %> #if close

<% end %> # holes form close
<% end %>#course form close



<script>
var selected = [];
var clickedholeid = $(".holeid").on('click', function(e) {
e.preventDefault();
alert($(e.currentTarget).html());
})
</script>


I want to pass user clicked hole-id to check if condition to display it
beacons within the page.My app is about Golf course game.
In this a course have 18 holes and each hole have 3
beacons(tip,approach,beaware) respectively. I alert user clicked hole id
in console but now i want to pass that value to if condition after holes
form in above code. Without that condition its display all 18 holes
beacons in edit page.(18 * 3)
So I need to stop that and default it display douse first hole beacons
after that if user perform click

If you want to evaluate a *client-side* variable value using Ruby on
the server you'll have to send it via AJAX. Otherwise include logic
in your JavaScript so the client can handle the checking.

function holeid(){
$.ajax({
type: "POST",
url: "course/edit/",
data: "Hole data="+ id,
success: function(id){
alert("Hole ID:"+ id );
}
});

Take a look at this gem: https://rubygems.org/gems/gon

Ryan Bates also did a Railscast about it.
