我在spring中添加上面的方法；

?

在xheditoer源码作了小小改动，添加一个参数把文件名传到服务器去：

function postFile(fromfile,toUrl,callback,onProgress)
		{
			xhr = new XMLHttpRequest(),upload=xhr.upload;
			xhr.onreadystatechange=function(){if(xhr.readyState===4)callback(xhr.responseText);};
			if(upload)upload.onprogress=function(ev){onProgress(ev.loaded);};
			else onProgress(-1);//不支持进度
			if(toUrl.indexOf("&") == -1 && (toUrl.indexOf("?") == -1)){
				toUrl += "?filename="+fromfile.fileName
			}else{
				toUrl += "&filename="+fromfile.fileName;
			}


			xhr.open("POST", toUrl);
			xhr.setRequestHeader('Content-Type', 'application/octet-stream');
			xhr.setRequestHeader('Content-Disposition', 'attachment; name="'+inputname+'"; filename="'+fromfile.fileName+'"');
			if(xhr.sendAsBinary)xhr.sendAsBinary(fromfile.getAsBinary());
			else xhr.send(fromfile);
		}

这个就可以FF中使用html5特用的Ajax上传文件传文件了

?

原来一直认为只能表单提交方式上传文件，现在该改一下了，哈哈
