王老师在不在？帮我看下，怎么固定宽度？
<script   language= "javascript "   type= "text/javascript ">
var   flag=false;
function   DrawImage(ImgD,intHeight)
{
var   image=new   Image();
image.src=ImgD.src;
if(image.width> 0   &&   image.height> 0)
{
      if(image.height   >   intHeight)
      {
          ImgD.width   =   image.width   /image.height   *   intHeight;
                  ImgD.height   =   intHeight;
      }
}
}

</script>

<img   src= "showing.asp?id=2 "   onload= "javascript:DrawImage(this,200); ">
上面是固定图片高度的代码，现在我想固定宽度？应该怎么改？

------解决方案--------------------
<script language= "javascript " type= "text/javascript ">
var flag=false;
function DrawImage(ImgD,intWidth)
{
var image=new Image();
image.src=ImgD.src;
if(image.width> 0 && image.height> 0)
{
if(image.width > intWidth)
{
ImgD.height = image.height /image.width * intWidth;
ImgD.width = intWidth;
}
}
}

</script>

晕死，固定高度都会了，固定宽度不是一个道理么？

<script language= "javascript " type= "text/javascript ">
function DrawImage(ImgD,intWidth)
{
var image=new Image();
image.src=ImgD.src;
if(image.width> 0 && image.height> 0)
{
if(image.width > intWidth)
{
ImgD.height = image.height/image.width * intWidth;
ImgD.width = intWidth;
}
}
}

</script>
