上传新附件时更换附件 [英] Replace attachment when uploading a new attachment

问题描述

我有一个简单的形式和身体领域。当用户上传附件时，我想删除已经在文档的正文字段中的任何附件。我怎样才能在我的保存按钮做到这一点。

我已经试图设置fileUpload控件上的固有名称，以始终将文件名更改为相同的名称，但这不会取代该文件，而是它添加一个新的文件，并添加一个新的序列号

 < xp：fileUpload id =fileUpload1 value =＃{userdoc.Body}filename =profileseUploadname =false>< / xp：fileUpload> 
  

在保存之前，我也尝试过在body字段中循环所有嵌入的附件，然后所有附件删除了，但我的新附件没有添加。

解决方案

有点晚，但万一有人像我一样Google ...

另外还有一个选项：NotesXSPDocument.getAttachmentList（rtitem）返回文档中的附件列表。每个条目都是

  var attList = docFile.getAttachmentList（files）; （i = 0; i< attList.size（）; i ++）{
 var att = attList.get（i）; 
 
 
 
 if（att.getState（）== 0）{// STATE_INDOCUMENT：'old'file：remove it 
 docFile.removeAttachment（files，att.getName ））; 
} else if（att.getState（）== 1）{// STATE_ADDED：这是新文件
 //保留
} 
} 
  

I have a simple form and body field. when user upload an attachment I want to remove any attachment already in the body field of the document. how can I do this in my save button.

I have tried to set the properites on the fileUpload control to always change the filename to tha same name but this does not replace the file, instead it adds a new file and add a new sequential number to it

<xp:fileUpload id="fileUpload1" value="#{userdoc.Body}" filename="profile"     seUploadname="false"></xp:fileUpload>

I have also tried to loop all embedded attachments in body field before before save, and all attachments are then removed, but my new attachment is not added.

解决方案

A little late, but in case anyone gets here just as I did through Google...

There's also another option: a NotesXSPDocument.getAttachmentList("rtitem") returns a list of attachments in the document. Each entry is of type DominoDocument.AttachmentValueHolder which has a getState() property that returns if a file was already in the document or just added. To remove the file that was already in the document you could add this SSJS code to a save button (assuming "files" is the name of the richtext item holding the files):

var attList = docFile.getAttachmentList("files");

for(var i=0; i<attList.size(); i++) {
  var att = attList.get(i);

  if (att.getState()==0) {      //STATE_INDOCUMENT: this is the 'old' file: remove it
    docFile.removeAttachment("files", att.getName() );
  } else if (att.getState()==1) {       //STATE_ADDED: this is the new file
           //leave it           
  } 
}
