先了解一下對象的幾個的屬性:
innerHTML:設(shè)置或獲取位于對象起始和結(jié)束標簽內(nèi)的 HTML
scrollHeight: 獲取對象的滾動高度,。
scrollLeft:設(shè)置或獲取位于對象左邊界和窗口中目前可見內(nèi)容的最左端之間的距離
scrollTop:設(shè)置或獲取位于對象最頂端和窗口中可見內(nèi)容的最頂端之間的距離
scrollWidth:獲取對象的滾動寬度
offsetHeight:獲取對象相對于版面或由父坐標 offsetParent 屬性指定的父坐標的高度
offsetLeft:獲取對象相對于版面或由 offsetParent 屬性指定的父坐標的計算左側(cè)位置
offsetTop:獲取對象相對于版面或由 offsetTop 屬性指定的父坐標的計算頂端位置
offsetWidth:獲取對象相對于版面或由父坐標 offsetParent 屬性指定的父坐標的寬度
