javascript - Rails 5: Trying to render divs with a single partial but keep the div class unique so that JQuery doesn't fire on all partials -


a bit of confusing title.

i trying implement bit of reddit comment system. can view post , add comment polymorphic. or, comment on comment.

my view looks so:

<h2>post:</h2> <div class="well">   <p>     <strong>title:</strong>     <%= @post.title %>   </p> <% if @post.description %>   <p>     <strong>description:</strong>     <%= @post.description %>   </p> <% end %> </div>  <% if current_user %>   <%= render "shared/comment_form" %> <% else %>   <p>log in add comments</p> <% end %>  <% if @post.comments.any? %>   <%= render "shared/comment_list" %> # comment_form inside of partial <% else %>   <p>no comments yet</p> <% end %>

inside of comment_list rendering of comment_form can comment on comment:

<h2>comments</h2> <ul>   <% @post.comments.each |co| %>     <li><%= co.body %></li>     <%= render "shared/comment_form" if current_user %>   <% end %> </ul>

finally, comment form itself:

<div id="comment-form" class="form-group">   <%= form_for @comment, remote: true, url: post_comments_path(@post) |f| %>     <%= f.text_area :body, required: true, rows: 5, class: "form-control" %>     <%= f.hidden_field :commentable_id, :value => @post.id %>     <%= f.hidden_field :commentable_type, :value => @post.class.name %>     <%= f.hidden_field :user_id, :value => current_user.id %>     <br>     <%= f.submit class: "btn btn-primary" %>   <% end %> </div> <span id="add-comment">add comment</span>

and jquery code acts on comment_form:

$(document).on('turbolinks:load', function() {   $("#comment-form").hide();   $('#add-comment').click( function() {     $("#comment-form").fadetoggle("fast");     ($("#add-comment").text() === "cancel") ? $("#add-comment").text("add comment") : $("#add-comment").text("hide");   }); });

my question is:

how separate these divs jquery doesn't fire on instances of id="comment-form? pass in erb tag <%= @post.class.name %><%= @post.id %>, again, keep variable universal. then, how implement unique id name in jquery code.

edit: got 1 part of question solved. left rest of wasn't able see.

you use prev() this:

$(document).ready(function() {     $('.comment-form').hide();      $('.add-comment').click( function(event) {     // store button has been clicked on variable     var eventtarget = $(event.target);      // find previous element #comment-form , id , toggle     eventtarget.prev('.comment-form').fadetoggle('fast');      // use eventtarget again     (eventtarget.text() === 'cancel') ? eventtarget.text('add comment') : eventtarget.text('cancel');   }); });
