I have tabs on a page that are giving me trouble. I think it is in the js code. Sometimes you have to doubleclick on the tabs, sometimes you don't.
This is using HAML in Rails, which I am not as familiar with. I also didn't write the original code. I am taking over on a project.
Here are the codes: HAML
#myTabs
 %ul.tab-buttons.tab-buttons--boxed.tab-buttons--left.js-tabs.nav-tabs
   %li.active.tab-button
    %a#tab1.tab-button-link.active{"data-toggle" => "tab", "data-projects" => "not_archived"} Current Projects
   %li.tab-button
    %a#tab2.tab-button-link{"data-toggle" => "tab", "data-projects" => "archived"} Archived Projects
.tab-content
 #tab1C.container
  %ul.list-project
   = render @projects
 #tab2C.container
  %ul.list-project
JS
$('.js-tabs li a:not(:first)').addClass('inactive');
  $('.container').hide();
  $('.container:first').show();
  $('.js-tabs li a').click(function(){
    var that = this;
    var t = $(that).attr('id');
    $.get("/projects", {projects: $(that).data("projects")}, function(){},'json')
      .done(function(data){
        var projects = data.projects;
        if($(that).hasClass('inactive')){
          $(that).removeClass('inactive');
          $(that).addClass('active');
          $('#'+t+'C .list-project').html(projects);
          $('.container').hide();
          $('#'+ t + 'C').fadeIn('slow');
        } else {
          $(that).removeClass('active');
          $(that).addClass('inactive');
          $('#'+t+'C .list-project').html(projects);
          $('.container').hide();
          $('#'+ t + 'C').fadein('slow');
      };
        $('.open-popup-link').magnificPopup(magnificPopupOptionsPermissionEmail);
      })
  });
I tried to show the codes in codepen but it isn't showing accurately. Codepen
