HTML (Rails) posted 6 months ago by christian

The HTML , in a layout file, for example application.html.erb:

   1  <div id="error-message" style="display:none">
   2  </div>

The JavaScript, rendered by for example create.js.erb: 

   1  <% if !@category.valid? %>
   2  <%
   3    errors = <<ERR
   4    <p>Please fix the following errors:</p>
   5    <ul>
   6      #{@category.errors.collect{|err| "<li>" + err[0] + " " + err[1] + "</li>" } }
   7    </ul>
   8  ERR
   9  %>
  10  $('#error-message').html('<%= escape_javascript(errors) %>');
  11  $('#error-message').show();
  12  <% else %>
  13  $('#error-message').hide();
  14  <% end %>
