又一个javascript自动调整图片大小的脚本 // 方法：setSelectReadOnly 用于设定极select控件ReadOnly,
// 这个一个模拟只读不是真的只读
// 使用了onbeforeactivate,onfocus,onmouseover,onmouseout事件
// 示例：< img src='img.jpg' onload='ImgAutoSize(ImgD,FitWidth,FitHeight)' > ;
// create by sl
// ---------------------------------------------------
function ImgAutoSize(imgD,FitWidth,FitHeight)
{
var image1=new Image();
image1.onload = function ()
{
if(this.width>0 && this.height>0)
{
if(this.width/this.height>= FitWidth/FitHeight)
{
if(this.width>FitWidth)
{
imgD.width=FitWidth;
imgD.height=(this.height*FitWidth)/this.width;
}
else
{
imgD.width=this.width;
imgD.height=this.height;
}
}
else
{
if(this.height>FitHeight)
{
imgD.height=FitHeight;
imgD.width=(this.width*FitHeight)/this.height;
}
else
{
imgD.width=this.width;
imgD.height=this.height;
}
}
}
image1 = null;
}
image1.src=imgD.src;
imgD.style.cursor = 'hand';
imgD.onclick= function(){openWin(this.src,'imgphoto',600,400)};
imgD.title = "点击在新窗口中查看原图";
}
