    Add this to your css:

    .carousel-control {
  display: none;
}

    Just look in the html.

    Do ctrl + f on your html file.

    And type in next or previous. You will see the next and previous classes stand.
    Just remove them.

    1. You can change the display property of a control by the .css() method.

    2. Use the slid.bs.carousel event to hide an arrow. If an item has the .active class at this point, it means that the item has just become active.

      This event is fired when the carousel has completed its slide transition.

    3. Use the slide.bs.carousel event to show an arrow. If an item has the .active class at this moment, it means that the item becomes inactive right now.

      This event fires immediately when the slide instance method is invoked.

    Please check the result. Is it what you want to achieve?

    var myCarousel   = $('#myCarousel');
var itemFirst    = myCarousel.find('.carousel-inner > .item:first-child');
var itemLast     = myCarousel.find('.carousel-inner > .item:last-child');
var controlLeft  = myCarousel.find('a.left.carousel-control');
var controlRight = myCarousel.find('a.right.carousel-control');

hideControl();

myCarousel.on('slid.bs.carousel', function() {
  hideControl(); 
});
myCarousel.on('slide.bs.carousel', function() {
  showControl(); 
});

function hideControl() {
  if ( itemFirst.hasClass('active') ) {
    controlLeft.css('display', 'none');
  }
  if ( itemLast.hasClass('active') ) {
    controlRight.css('display', 'none');
    myCarousel.carousel('pause');  // stop from cycling through items
  } 
}

function showControl() {
  if ( itemFirst.hasClass('active') ) {
    controlLeft.css('display', 'block');
  }
  if ( itemLast.hasClass('active') ) {
    controlRight.css('display', 'block');
  }
}
