常用JS圖片滾動（無縫、平滑、上下左右滾動）代碼大全innerHTML: 設置或獲取位于對象起始和結束標簽內的 HTMLscrollHeight: 獲取對象的滾動高度。scrollLeft: 設置或獲取位于對象左邊界和窗口中目前可見內容的最左端之間的距離scrollTop: 設置或獲取位于對象最頂端和窗口中可見內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以下包含四種方向的滾動代碼，粗體部分需要自行修改，可修改成更復雜的代碼，如圖文混排、加邊框、限制圖片大小等。增大width時，應該相應增加一些圖片（應該是使所有圖片組成的總寬度大于設定的width），即使是重復的，否則會在滾動一會兒后停下來，圖片不宜太大，否則在IE下滾動緩慢!-----------------------------------------------------------------------代碼:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html;
