ASP中如何控制图片大小,(如何实现等比缩放)? 放入head里面 <script language="JavaScript"> <!-- var flag=false; function DrawImage(ImgD){ var image=new Image(); image.src=ImgD.src; if(image.width>0 && image.height>0){ flag=true; if(image.width/image.height>= 164/112){ if(image.width>164){ ImgD.width=164; ImgD.height=(image.height*164)/image.width; }else{ ImgD.width=image.width; ImgD.height=image.height; } ImgD.alt=image.width+"×"+image.height; } else{ if(image.height>112){ ImgD.height=112; ImgD.width=(image.width*112)/image.height; }else{ ImgD.width=image.width; ImgD.height=image.height; } ImgD.alt=image.width+"×"+image.height; } } } //--> </script> 图片调用 <a href="<%=trim(rs("picurl"))%>" target="_blank"><img src="<%=trim(rs("imgurl"))%>" border="0" width="164" height="112" onload="javascript:DrawImage(this);"></a> 这样可以实现等比例缩放!
