Jfinal+DWZ使用uploadify插件实现文件上传

upload.jsp

var htmlHead="
已上传的文件：
";
var htmlBody="";
var htmlFoot="
";
function onComplete(event, queueId, fileObj, response, data){
var obj = eval( "(" + response + ")" );//转换为JSON对象
htmlBody+="
";
htmlBody+="";
htmlBody+=""
+obj.filename+" （"+obj.filesize+"）";
htmlBody+="
";
$("#fileList").html(htmlHead+htmlBody+htmlFoot);
}
//删除文件ajax请求
function deleteFile(id){
$("#file_"+id).load("Main/post/deletefile/"+id);
$("#file_"+id).remove();
htmlBody=$("#fileHtmlBody").html();
}
//close前删除已上传的文件
function deleteUploaded(){
$(".uploaded").each(function(){
var fileid = $(this).val();
deleteFile(fileid);
});
}

------------------------------------------------------------------------

uploader="styles/dwz/uploadify/scripts/uploadify.swf"//必需，uploadify使用的插件
cancelImg="styles/dwz/uploadify/cancel.png" 
script="Main/post/uploadfile"//必需，上传的服务端入口
fileQueue="fileQueue" //对应下方的div，用来显示上传进度
auto="true" 
OnComplete="onComplete"/> //单个文件上传完成执行的js函数


 //此块用于显示已上传完成的文件
