// 获取左右箭头元素

// 图片滚动函数
function carouselScroll(direction) {

  var maxScrollLeft = container.scrollWidth - container.clientWidth;
  var increment = 20 * direction;

  container.scrollLeft += increment;

  if (container.scrollLeft < minScrollLeft) {
    container.scrollLeft = maxScrollLeft;
  } else if (container.scrollLeft > maxScrollLeft) {

  }
};

// 给左右箭头绑定事件
prev.addEventListener("click", function() {
  carouselScroll(-1);
});

next.addEventListener("click", function() {
  carouselScroll(1);
});
