通过事件改变图片
<script language=javascript>
function chuli()
{
document.getElementByName( "qian1 ").src= "sTDButton.jpg ";
}
</script>


下面是图
<img border= "0 " id= "qian1 " name= "qian1 " onclick= "Chuli() " onmouseover= "nereidFade(this,100,1,5) " style= "FILTER: alpha(opacity=0) "
onmouseout= "nereidFade(this,0,1,5) " title= "世代服务网 " src= "sTDButton.jpg "width= "96 " height= "32 " runat= "server ">

怎么老是提示找不到对象啊 ？？？？？？？这是怎么回事啊？？？
