火狐IE下获取完整文件路径名的方法

抄：

 

以下为引用的内容：

<input name="upfile1" type="file" id="upfile1" onchange="SeePicNew2('uploadfield1',this);" />

<div class="divpre" id='uploadfield1'></div>

function SeePicNew2(imgdid,f) {

if(f.value=='') return ;

var newPreview = document.getElementById(imgdid);

// 这段代码是关键，如果是FF，则f.fles为真

if (f.files) {

var filepath = f.files.item(0).getAsDataURL();

} else {

var filepath = 'file:///'+f.value.replace(////g,"/").replace(//:/,"|");

}

var image = new Image(); var ImgD = new Image();

ImgD.src = filepath;

image.src = ImgD.src; FitWidth = 150; FitHeight = 100;

if(image.width>0 && image.height>0)

{

if(image.width/image.height>= FitWidth/FitHeight)

{

if(image.width>FitWidth)

{

ImgD.width=FitWidth;

ImgD.height=(image.height*FitWidth)/image.width;

}

else

{

ImgD.width=image.width;

ImgD.height=image.height;

}

}

else

{

if(image.height>FitHeight)

{

ImgD.height=FitHeight;

ImgD.width=(image.width*FitHeight)/image.height;

}

else

{

ImgD.width=image.width;

ImgD.height=image.height;

}

}

}

newPreview.style.width = ImgD.width+"px";

newPreview.style.height = ImgD.height+"px";

if(window.navigator.userAgent.indexOf("MSIE") < 1)

{

newPreview.style.background = "url('"+ImgD.src+"') no-repeat";

}

else

{

newPreview.style.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='"+ImgD.src+"',sizingMethod='scale')";

}

ImgD = image = null;

//newPreview.filters.item('DXImageTransform.Microsoft.AlphaImageLoader').src = f.value;

}
