JS +div图片转换

<script language="javascript">
function change()
{
document.getElementById("").src="新图";
}

function rechange()
{
document.getElementById("").src="旧图";
}
</script>
<div src="新图" onMouseOver="change()" id="" onMouseOut="rechange()">
</div>

恩， 很不错， 不知道你有什么问题

你要的是不是这种效果

<script language="javascript"> function change(imgobj) { imgobj.src=" http://www.baidu.com/img/baidu_logo.gif"; }

function rechange(imgobj) { imgobj.src=" http://cache.soso.com/wenwen/i/wenwen_logo.gif"; } </script> <div src="新图" onMouseOver="change(imgtu)" id="" onMouseOut="rechange(imgtu)"> <img src=" http://cache.soso.com/wenwen/i/wenwen_logo.gif" id="imgtu"/> </div>

document.getElementById你要做什么

DIV有src属性么..貌似没有吧
