  • clientTop: 一个元素顶部边框的宽度(以像素表示)
  • HTMLElement.offsetParent:
    • 指向最近的包含该元素的定位元素。
    • 如果没有定位的元素,则 offsetParent 为最近的 table, table cell根元素(标准模式下为 html;quirks 模式下为 body)。
    • 当元素的 style.display 设置为 "none" 时,offsetParent 返回 null
    • offsetParent 很有用,因为 offsetTopoffsetLeft 都是相对于其内边距边界的

  • offsetLeft,offsetTop: 相对于 offsetParent 元素的距离,而 offsetParent 指的是一个元素最近的父级定位元素,如果没有定位元素就是文档根节点

  • offsetLeft,offsetTop: 当前元素左上角相对于 HTMLElement.offsetParent 节点的左边界偏移的像素值
