ajaxfileupload+servlet 后台不知道如何写 下面是我的js代码

[lianhy]

$("#savePic").click(function(){
var workId="1";
var imgList=$('input[class="imgFile"]');
var arrId=new Array();
for(var i=0;i<imgList.length;i++){
arrId[i]=imgList[i].id;
}
$.ajaxFileUpload({
url:"servlet/FileUpload?workId="+workId,
secureuri:false,
fileElementId: arrId,
dataType: 'json',
success:function(data,status){

},
error:function(data,status,e){

}






});

你传递文件id没用，不会上传文件内容。。用jquery.form.js这个插件。服务器端和普通表单提交一样，怎么写就怎么写，只是不能再服务器端跳转，客户端浏览器不会跳转
