图片宽度自适应,高度等比例变化的js
<img src="upload/20061124114040.JPG" alt="" name="img1" border="0" id="img1">
<script language="javascript">
var flag=false;
DrawImage(img1);
function DrawImage(ImgD){
var image=new Image();
image.src=ImgD.src;
if(image.width>0 && image.height>0){
flag=true;
if(image.width>=700){
ImgD.width=700;
ImgD.height=(image.height*700)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
}
}
</script>
另外加一段通过计算控制当前图片大小的js
<img src="654662.jpg" border=0 id="thisImg" onload="(this.width = this.width / 100 * 28) ; this.height = this.height / 100 * 28)">
这是当天图片大小的 28%
