    我在一个 pull to refresh 组件里套了一个 swiper
    swiper 里每一页都是一个 droppable 的 list
    list 里面是 dragable 的 item
    每次拖拽 item 就会导致 swiper 和 pull to refresh 都触发
    试着在 dragable 的 item 上 on touch move e.stopPropagation 或者 preventDefault 都没效果
    怎么解决这个问题也毫无头绪
  • item
  • swiper
  • dragable
  • Refresh

    拖拽 item 没有触发 pull to refresh ，这个应该是正确行为吧

    @dablwow 是 demo 里的吗
    我后来找了个控制下拉高度的属性 在 ondragstart 的时候设为 0 就可以避免下拉
    但是 swiper 的左右滑动靠在 ondragstart 的时候设置 allow touch move 为 false 就不行
