validate the file type, size when adding an attachment to PDF

[WhatCindy]

Hi all,

I have issues for creating a attachment button. I have validated the file type (e.g. pdf, doc, tiff, ect.) and total size is less than 9MB when adding files to PDF. When I select the attachment button to add the file, the total size is not add everytime I add the file. It is only display of each file. I cannot figure out why is coding is not working. I have spent two days to work on it but unsucessful.

I have attached the testing form. It is easy for you to follow.

I place coding in event:click under attachment button.

Here is my coding:

var oObj = event.target;
var aTotal;
var cFiles = oObj.dataObjects;
var counter = 0;
var nTotalSize;
var nTotalKb = "83886080"  //.......... kilobytes

if(attachmentsList.length > 0)
{
 
  oObj.importDataObject(cFiles.length);
  var oDataObj = oObj.getDataObject(cFiles.length);
  attachmentsList.addItem(oDataObj.path);
 
  NoOfAttachments.rawValue = cFiles.length+1;
 
 
 
  aTotal = (cFiles.length)
  aTotal =  oDataObj.size
  FileSize.rawValue = aTotal;
 
AttachmentDescription.rawValue;
var cFiles = AttachmentDescription.rawValue;
var oObj = event.target;
//oObj.removeDataObject(cFiles);
//oObj.importDataObject(cFiles);



//oObj.importDataObject(cFiles);
//var oDataObj = oObj.getDataObject(cFiles);
//
var fileName = oDataObj.path;

var fileType = fileName.substring(fileName.lastIndexOf("."));

attachmentsList.rawValue = fileName;

if(fileType != ".pdf" && fileType != ".PDF" && fileType != ".JPG" &&
  fileType != ".jpg" && fileType != ".tif" && fileType != ".TIF"&&
  fileType != ".tiff" && fileType != ".TIFF"){
  xfa.host.messageBox("Incorret Document");
  oObj.removeDataObject(cFiles);
  }

  }

else
{

oObj.importDataObject(counter.value);
var oDataObj = oObj.getDataObject(counter.value);
  attachmentsList.addItem(oDataObj.path);
NoOfAttachments.rawValue = 1;

 


}

Thanks for your help.
