Input check affecting all classes

Question

How can I add a class using jquery without it affecting all divs assigned to that class name? There has to be an easy way around this? I'm already using $(this) for the input check, so how can I make the action unique to the toggle it's on?

$('input:checkbox').change(function(){
   if($(this).prop('checked')==true){ 
      $(this).closest(".row").toggleClass('highlight', this.checked); 
      $('.overlay').fadeIn(300).delay(3000).fadeOut();
      $(".loader").addClass('active').fadeIn(300).delay(3000).fadeOut();
      setTimeout(function(){
         $(".complete").addClass('active').delay(3300).fadeIn(300).delay(1000).fadeOut()
      }, 3100);
   } else {
      $('.loader').hide(); 
      $('.complete').hide(); 
      $('.overlay').hide(); 
      $(".error").addClass('active').fadeIn(300).delay(2000).fadeOut(200)
   }
});

My jsfiddle.

Just like you are using $(this).closest(".row"), instead of $('.loader'), $('.complete') and $('.error') you can use:

var container = $(this).closest(".toggle-container")
container.find('.loader')
container.find('.complete')
container.find('.error')

Demo below:

$('input:checkbox').change(function() {
  var container = $(this).closest(".toggle-container");
  if ($(this).prop('checked')) {
    $(this).closest(".row").toggleClass('highlight', this.checked);
    $('.overlay').fadeIn(300).delay(3000).fadeOut();
    container.find(".loader").addClass('active').fadeIn(300).delay(3000).fadeOut();
    setTimeout(function() {
      container.find(".complete").addClass('active').delay(3300).fadeIn(300).delay(1000).fadeOut()
    }, 3100);
  } else {
    container.find('.loader').hide();
    container.find('.complete').hide();
    $('.overlay').hide();
    container.find(".error").addClass('active').fadeIn(300).delay(2000).fadeOut(200)
  }
});
