应该挺简单

<IMG src="../youxi/up-moni/<%Response.Write(rs("图2"))%>" alt="<%Response.Write(rs("名称"))%>2" border=0 onload='javascript:if(this.width>240)this.width=240;if(this.height>180)this.height=180'>

如何把上面的代码 写在<script language="javascript">
因为写在 body中onload有时后加载失败
如何在 img 中加个 id= 写在<script language="javascript">中

[nanchangfantasy]

没见过这种写法

需要 new Image()

然后判断加载是否完成,写入宽度

<script language="JavaScript">
<!--
//图片按比例缩放
var flag=false;
function DrawImage(ImgD,iwidth,iheight){
//参数(图片,允许的宽度,允许的高度)
var image=new Image();
image.src=ImgD.src;
if(image.width>0 && image.height>0){
flag=true;
if(image.width/image.height>= iwidth/iheight){
if(image.width>iwidth){
ImgD.width=iwidth;
ImgD.height=(image.height*iwidth)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
ImgD.alt=image.width+"×"+image.height+"点击察看原始尺寸";

用这个写法试试吧
