如何在移动视图中点击箭头时左右滚动内容？

Question

我有一个 fiddle，它的工作方式是当我在移动视图中使用它时，方框会水平滚动。

我为此使用的 CSS 代码是：

@media only screen and (max-width: 767px)
{
.product-all-contents
{
   overflow-x: auto;
}

.product-contents .product{
  min-width: 50.795%;
  margin: 0 2%;
  padding-top: 3.91%;
  padding-left: 3.91%;    
  padding-right: 3.91%;
  }
}

问题陈述：

我想知道我应该在 fiddle 中进行哪些更改，以便 当我在移动视图中点击箭头时（如下面的橙色箭头标记的屏幕截图所示） 内容向左移动，反之亦然。

我认为最好的解决方案是 jQuery、scrollLeft() 和 scrollRight()，但我不确定如何在 fiddle.

Answer 1

对于你的问题，你需要一些东西

设置两个按钮以在您的代码中设置侦听器
获取初始位置以便计算幻灯片

让 divMain = $('.product-all-contents')[0]; 让 position = $(divMain).children().position().left; const slideAmount = 150;

这 3 个变量将是代码的主要值

最后听幻灯片

$('#arrow-right').click(函数() { $(divMain).animate({ 向左滚动：位置 + slideAmount }, 500); 位置 += slideAmount; })

希望这对您有所帮助 :>

$(document).ready(function() {
  let divMain = $('.product-all-contents')[0];
  let position = $(divMain).children().position().left;
  const slideAmount = 150;

  $('#arrow-right').click(function() {
    $(divMain).animate({
      scrollLeft: position + slideAmount
    }, 500);
    position += slideAmount;
  })

  $('#arrow-left').click(function() {
    $(divMain).animate({
      scrollLeft: position - slideAmount
    }, 500);
    position -= slideAmount;
  })
});
