本文主要介绍了css3手动实现pc端横向滚动,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

由于容器隐藏横向滚动条后,移动端横向滚动效果不受影响,但是pc端是无法通过鼠标进行横向滚动,因此需要自己手动实现效果。

  • draggable="false",通过设置draggable,是可以设置html不允许拖拽效果,通过拖拽可以初步实现pc端横向滚动行为。
    • draggable的兼容性是最好HTML属性
    • css样式-webkit-user-drag: none;也可以实现类似效果,兼容性不太好,移动效果大部份都有效
  • user-select:属性可以设置是否允许用户选择页面中的图文内容
  • mousedownmouseup:通过设置鼠标事件,实现鼠标按下后,坐标位置不一样,让容器调用scrollTo就可以实现滚动效果。
  • wheel:通过滚动事件,在容器内滚动滚轴可以横向滚动
  • getBoundingClientRect,记录每个图标的x位置,通过前后位置是否变化,如果不变化,鼠标单击的时候就可以触发单击事件。因为mousedown事件发生也会触发click事件
