您好，下面的代码使用 adobe acrobat 合并 pdf。它可以工作，但我希望将页码添加到文档中，这样如果我合并 2 个文档，每个文档有 4 页，页码会从 1 变为 8。如何做到这一点？

代码如下：

     ' --> Settings, change to suit
    Const MyPath = "C:\mypath" '"C:\Temp" ' Path where PDF files are stored

【解决方案1】：

附加了一个独立的 VBS/VBA 脚本，它将页码作为页脚添加到您的 pdf 中。您可以在保存 pdf 或之后执行之前取出您需要的部分并写入脚本。

完整脚本：

File = "D:\Test.pdf"

Set App = CreateObject("Acroexch.app")      '//start acrobat
app.show                                    '//show Acrobat or comment out for hidden mode
Set AVDoc = CreateObject("AcroExch.AVDoc")
Set AForm = CreateObject("AFormAut.App")   '//get AFormAPI to execute js later

If AVDoc.Open(File,"") Then
    '//write JS-Code on a variable
    Ex = "  //  set Date, filename and PageNo as footer "&vbLF _
      & "  var Box2Width = 50  "&vbLF _
      & "  for (var p = 0; p < this.numPages; p++)   "&vbLF _
      & "   {   "&vbLF _
      & "    var aRect = this.getPageBox(""Crop"",p);  "&vbLF _
      & "    var TotWidth = aRect[2] - aRect[0]  "&vbLF _
      & "     {  var bStart=(TotWidth/2)-(Box2Width/2)  "&vbLF _
      & "         var bEnd=((TotWidth/2)+(Box2Width/2))  "&vbLF _
      & "         var fp = this.addField(String(""xftPage""+p+1), ""text"", p, [bStart,30,bEnd,15]);   "&vbLF _
      & "         fp.value = ""Page: "" + String(p+1)+ ""/"" + this.numPages;  "&vbLF _
      & "         fp.textSize=6;  fp.readonly = true;  "&vbLF _
      & "         fp.alignment=""center"";  "&vbLF _
      & "     }  "&vbLF _
      & "   }  "
    '//Execute JS-Code
       AForm.Fields.ExecuteThisJavaScript Ex
    msgBox("Done")
end if

Set AVDoc = Nothing
Set APP = Nothing

如果您只想在脚本中接管，您真正需要的部分：

Set AForm = CreateObject("AFormAut.App")  
Ex = "  //  set Date, filename and PageNo as footer "&vbLF _
  & " .....

  & " .....
  & "   }  "
'//Execute JS-Code
 AForm.Fields.ExecuteThisJavaScript Ex

这还演示了如何通过 VBS/VBA 使用/执行 AcroJs 而无需转换为 JSO（Java 脚本对象）。

祝你好运，莱因哈德
