javascript - SyntaxError in BookmkfoldersController#index, unknown regexp options - dv -


i want make web application, , everything's been working fine far. however, actionview wrong. seems can't recognize closed html tags. every time sees closed parentheses, claims these unclosed. however, think are! i've posted error log below, knows what's going on...!

i following error :

 syntaxerror in bookmkfolderscontroller#index  app/views/bookmkfolders/index.html.erb:16: unknown regexp options - dv  app/views/bookmkfolders/index.html.erb:17: syntax error, unexpected '<'

and file index.html.erb

<ul class="board-canvas" data-update-url = "<%=sort_bookmkfolders_url %>">   <% @bookmkfolders.each |bookmkfolder| %>       <div class="panel-wrapped">           <li id="<%=bookmkfolder.id%>" class="panel" style = "background-color:<%=bookmkfolder.bookmkfoldercolor%>">             <%= text_field_tag :test, "", class: 'thval' %>             <h2 class= "panel-title" ><%= bookmkfolder.bookmkfoldertitle %></h2>             <div class="panel-menu">               <%= button_tag "add bookmark-url", type: 'button', class: 'addfolder js-add-card' %>               <div class="add-card-form">                 <%= simple_form_for @bookmkfolder, remote: true, url: {action: "<%= @bookmkfolder.id %>"} |k| %>                 <%= k.input_field :bookmktitle, class: 'board-make-input', autocomplete: :off, autocorrect: :off, spellcheck: false, placeholder: 'add bookmark' %>                 <%= button_tag "save", type: 'submit' , class: 'save-button js-save-card' %>                 <%= button_tag "", type: 'button', class: 'delete-button' , "<span class="fa fa-times fa-1x" aria-hidden="true"></span>".html_safe %>                 <% end %>               </div>   # error message app/views/bookmkfolders/index.html.erb:16             </div>           </li>            <ul class="card-list">             <% bookmkfolder.@bookmks.each |bookmk| %>               <li class ="card-item">                 <%= link_to "","<%= bookmk.bookmktitle %>", class: 'card-link' %>                 <%= image_tag "#", class: 'card-thumbnail' %>                 <p class = "card-txt"><%= bookmk.bookmktitle%></p>               </li>             <%end%>           </ul>       </div>  <%end%> </ul>

and extracted sources bookmkfolders_controller.

def index  @bookmkfolders = bookmkfolder.all  @bookmkfolders = bookmkfolder.order("sequence")  @bookmkfolder = bookmkfolder.new  @bookmks = bookmk.all  @bookmk = bookmk.new end  def newfolder   #  redirect_to '/bookmkfolder/createfolder' end  def createfolder  colors = ['#c9ddff', '#c9ffdd', '#ffd2c9', '#c9caff', '#fdc9ff', '#fffdc9',   '#c9fffc', '#ffc9c9', '#ffe5c9', '#eaffc9']   puts bookmkfolder.methods   @bookmkfolder = bookmkfolder.new(bookmkfolder_params)   @bookmkfolder.user = current_user   @bookmkfolder.sequence = bookmkfolder.count + 1   @bookmkfolder.bookmkfoldercolor = colors.at(rand(colors.size))    respond_to |format|     if @bookmkfolder.save       format.html { redirect_to @bookmkfolder, notice: 'bookmkfolder  created.' }       format.js {}       format.json { render :show, status: :created, location: @bookmkfolder }      else       format.html { render :new }       format.json { render json: @bookmkfolder.errors, status:     :unprocessable_entity }     end   end end

you can't nest <% %> this:

<%= simple_form_for @bookmkfolder, remote: true, url: {action: "<%= @bookmkfolder.id %>"} |k| %>

once open <% using ruby, can use variables in code, so:

<%= simple_form_for @bookmkfolder, remote: true, url: { action: @bookmkfolder.id } |k| %>

not related current error, notice second button_tag incorrect (aside using nested double quotes), can't pass argument trying "<span>...</span>".html_safe.

what looking pass block, this:

<div class="add-card-form">   <%= button_tag "", type: 'button', class: 'delete-button' %>     <span class="fa fa-times fa-1x" aria-hidden="true"></span>   <% end %> </div>

you can read button_tag in the docs.
