点击更换图片的问题
单击图片的某一部分，变成原位置大小不变的另一幅图片
<map name= "Map2 ">
<area shape= "rect " coords= "4,6,94,32 " href= "# " target= "_self " onClick= "javascript:goto1(); ">
<area shape= "rect " coords= "99,5,188,33 " href= "cpzsdetail1.asp " target= "_self " onClick= "javascript:goto2(); "> </map>
function goto1()
{
<img src= "images/y1.jpg " width= "581 " height= "42 " border= "0 " usemap= "#Map2 ">
}
function goto2()
{
<img src= "images/y2.jpg " width= "581 " height= "42 " border= "0 " usemap= "#Map2 ">
}
</script>
上边是我写的，是不是不该用function 该如何修改呢？
非常感谢
[解决办法]
<img src= "1.jpg " onclick= "this.src= '2.jpg ' ">
