我是用uploadify做的多文件上传,
如图,点击“开始上传”,文件上传到服务器(页面下面有一个提交按钮的,我没有截图出来,点击“开始上传”时还没有提交整个页面),如何将要上传的文件(文件个数不定)进行重命名,图上原名为grass.jpg和look.jpg,修改成以 软件编号+序号的方式,即2013122616231.jpg和2013122616232.jpg存储到服务器呢?
上传页面软件标号name定为appNo,在uploadify后台处理的servlet中,我使用
String appNo = request.getParameter("appNo");获取不到appNo。只要获取到了appNo就好弄了请教如何解决。
------解决方案--------------------
<a href="javascript:$('#uploadify').uploadifySettings('scriptData',{'type':$('#TextBox1').val()}); jQuery('#uploadify').uploadifyUpload()">
用这个方法吧。本身有这个 uploadifySettings
------解决方案--------------------
if("appNo".equals(item.getFieldName())){
String appNo= new String(item.getString())
这俩一起用 就取出来了 你好好看 用点心
------解决方案--------------------
我以前写了一个 给你自己看吧 ,我这个当时乱码 ,转换了一下 。
