Answer 1

//图片按比例缩放
var flag=false;
function DrawImage(ImgD){
var image=new Image();
var iwidth = 150; //定义允许图片宽度
var iheight = 100; //定义允许图片高度
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;
}
else{
if(image.height>iheight){ 
ImgD.height=iheight;
ImgD.width=(image.width*iheight)/image.height; 
}else{
ImgD.width=image.width; 
ImgD.height=image.height;
}
ImgD.alt=image.width+"×"+image.height;
}
}
} 
//调用：<img src="图片" onload="javascript:DrawImage(this)">
