javascript实现简单的走马灯

是的，最近都在做大学生也能做的东西，anyway,  拓宽知识面，js远比我想象的强大。

 (忽视那个asp.net的变量声明，那个是从数据库取的数据)

<div id="pro"><a href="product_type.aspx?product_type_id=9" class="a_display"><div class="title"><h1>产品推荐</h1><div class="go"></div></div></a>
    <div id="picdemo"><pre name="code" class="html">            <%=table_define %>
							<tbody>
							<tr>
							<td id="picdemo1" valign="top" >
			<%=product_overview %>
            				</td>
							<td id="picdemo2" valign="top" >
							</td>
							</tr></tbody></table>
    </div>
</div>

				  <script>
				      var speed = 30
				      picdemo2.innerHTML = picdemo1.innerHTML
				      function MarqueePic() {
				          if (picdemo2.offsetWidth - picdemo.scrollLeft <= 0) {
				              picdemo.scrollLeft -= picdemo1.offsetWidth
				          }
				          else {
				              picdemo.scrollLeft = picdemo.scrollLeft + 1
				          }
				      }
				      var MyMarPic = setInterval(MarqueePic, speed)
				      picdemo.onmouseover = function () { clearInterval(MyMarPic) }
				      picdemo.onmouseout = function () { MyMarPic = setInterval(MarqueePic, speed) }
				  </script>
