可以获取 .rc-virtual-list-holder 的

temp2.getBoundingClientRect().y + temp2.getBoundingClientRect().height

和 .rc-virtual-list-holder-inner 的

temp3.getBoundingClientRect().y + temp3.getBoundingClientRect().height

是否相等,不过感觉还是 getScrollInfo 暴露更多信息更好,这些写就耦合了 dom 结构

from virtual-list.

研究了下上面的方法不太准,可以使用下面的方法

const RC_VIRTUAL_LIST_HOLDER_CLASS = '.rc-virtual-list-holder'

export const isScrollBottom = (root: HTMLElement) => {
  const virtualList = root.querySelector(RC_VIRTUAL_LIST_HOLDER_CLASS)
  if (!isDef(virtualList)) {
    throw virtualError(`cannot find class ${RC_VIRTUAL_LIST_HOLDER_CLASS}`)
  }
  return virtualList.scrollTop >= virtualList.scrollHeight - virtualList.clientHeight
}

export const isScrollTop = (root: HTMLElement) => {
  const virtualList = root.querySelector(RC_VIRTUAL_LIST_HOLDER_CLASS)
  if (!isDef(virtualList)) {
    throw virtualError(`cannot find class ${RC_VIRTUAL_LIST_HOLDER_CLASS}`)
  }
  return virtualList.scrollTop <= 0
}

export const hasScroll = (root: HTMLElement) => {
  const virtualList = root.querySelector(RC_VIRTUAL_LIST_HOLDER_CLASS)
  if (!isDef(virtualList)) {
    throw virtualError(`cannot find class ${RC_VIRTUAL_LIST_HOLDER_CLASS}`)
  }
  return virtualList.scrollHeight > virtualList.clientHeight
}

from virtual-list.
