有位朋友给了我一个函数,可我不会用:哈哈 楼上的和我碰到过的情况一样
给你代码吧 废话少说<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>= 524/393){
if(image.width>524){
ImgD.width=524;
ImgD.height=(image.height*524)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
ImgD.alt=image.width+"×"+image.height;
}
else{
if(image.height>393){
ImgD.height=393;
ImgD.width=(image.width*393)/image.height;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
ImgD.alt=image.width+"×"+image.height;
}
}
}

</script>
