关于批量预览下载的问题

DemonHuan

如何实现对图片的批量预览及下载功能？

jishuang

附件组件上的图片吗？

DemonHuan

是的！

jishuang

5.2.7版本平台没有 提供contents组件可以滑动预览
需要自己到网上查找jquery等是否有这样的插件，然后自己获取要预览的图片的url，动态创建这样的的滑块视图创建image，把url给image展现

批量下载可以自己在后端把要批量下载的文件下载到服务端，然后压缩，前端下载的时候下载生成压缩包
后端下载参考http://bbs.wex5.com/forum.php?mod=viewthread&tid=40457

BeX5 的哪个版本提供相关的组件？

jishuang

5.3的版本中都有

DemonHuan

现在 我可以实现获取 附件中的相关信息，例如：docName，docID, docPath 等，但是现在我应该使用什么方法获取通过组件（attachmentEditor）传入到文档服务器中的文件呢？

我是用getDocUrl(String docPath,String urlPattern,boolean isFormSubmit) 获取的字符串，打印是这样的：“/UI/system/service/doc/common/uploadDoc.j?dochost=http://192.168.1.96:8080/DocServer70323-defaultDocNameSpace?key=63c386a3db4f2e240d7ab67834d4c2949366948889ea1cc07677cddb413052dde7b7c25fa5598086a02f8d2ad476cf3a5aab6cd57d647193b35d71208bffe2ffa4c19f2c84bbee46fc4344b73b9f5963“  还是没明白怎么下载？

我使用平台给的方法：
Docs docs = new Docs();
Doc doc = (Doc) docs.query(null, docPath, null, null, null).get(docid);
File outPutFile = new File("f:/"+((AbstractDoc) doc).getsDocName());                
((AbstractDoc) doc).download(new FileOutputStream(outPutFile));
