如何使幻灯片仅在第一次单击时向左移动并在第一次单击时拒绝向左移动？

Question

我的幻灯片区域在单击左键时向右滚动，但是那里什么也没有，所以有没有办法锁定第一次单击，以便只有先向右滚动时才能向左滚动？还有一种方法可以在滚动到最后一个后锁定滚动条吗div?

var $slider = $("#recent-container")

$("#right-button").click(function() {
  $slider.css("left", "-=932px")
});

$("#left-button").click(function() {
  $slider.css("left", "+=932px")
});

您可以尝试将按钮功能更改为仅在 recent-container 不在末尾时才更改 CSS。例如，对于右键：

  var $slider = $("#recent-container");
  $("#right-button").click(function() {
    if ($slider.position().left + $slider.width() > 0) $slider.css("left", "-=932px");
  });

  $("#left-button").click(function() {
    if ($slider.position().left < 0) $slider.css("left", "+=932px");
  });
