javascript - 在 Acrobat 类型库 10.0 JSObject 中使用 pageNum 属性返回 RunTime 错误 438

Question

我需要获取页码才能从 .PDF 文档中的特定页面中提取文本。我正在使用 Excel VBA 函数，该函数利用 Acrobat 类型库 10.0 中的 JSObject

这是代码片段，当我尝试从 Doc 对象引用 pageNum 属性时，代码会出现问题。我试图避免使用 AV 层并仅使用 PD 层，因此我的宏仅在后台运行并且不调用 Acrobat 应用程序。

Function getTextFromPDF_JS(ByVal strFilename As String) As String

   Dim pdDoc As New AcroPDDoc
   Dim pdfPage As Acrobat.AcroPDPage
   Dim pdfBookmark As Acrobat.AcroPDBookmark

   Dim jso As Object
   Dim BookMarkRoot As Object
   Dim vBookmark As Variant
   Dim objSelection As AcroPDTextSelect
   Dim objHighlight As AcroHiliteList
   Dim currPage As Integer
   Dim strText As String
   Dim BM_flag As Boolean
   Dim count As Integer
   Dim word As Variant


   strText = ""
   If (pdDoc.Open(strFilename)) Then


      Set jso = pdDoc.GetJSObject
      Set BookMarkRoot = jso.BookMarkRoot

      vBookmark = jso.BookMarkRoot.Children


    'Add a function call to see if a particular bookmark exists within the .PDF
    Set pdfBookmark = CreateObject("AcroExch.PDBookmark")

    BM_flag = pdfBookmark.GetByTitle(pdDoc, "Title Page")

If (BM_flag) Then

   For i = 0 To UBound(vBookmark)

        If vBookmark(i).Name = "Title Page" Then

            vBookmark(i).Execute
            jso.pageNum


         Set pdfPage = pdDoc.AcquirePage(pageNum)
         Set objHighlight = New AcroHiliteList
         objHighlight.Add 0, 10000 ' Adjust this up if it's not getting all the text on the page
         Set objSelection = pdfPage.CreatePageHilite(objHighlight)

         If Not objSelection Is Nothing Then
            For tCount = 0 To objSelection.GetNumText - 1
               strText = strText & objSelection.GetText(tCount)
            Next tCount
         End If

         Exit For
         End If
pdDoc.Close




End If


End If

   getTextFromPDF_JS = strText

End Function

Answer 1

jso.pageNum = 0; 设置页码

pageNo = jso.pageNum; 获取页码

编辑：3.3.19

嗯，看来您必须使用 AVDoc 才能通过 jso.pageNum 获取当前的实际页面。此外，如果您使用 AVdoc，Acobat 窗口将隐藏在后台。例子：

strFilename = "d:\Test2.pdf"
set avDoc = CreateObject("AcroExch.AVDoc")
If (avDoc.Open(strFilename,"")) Then
    Set pdDoc = avDoc.getPDDoc()
    Set jso = pdDoc.GetJSObject
    pageNo = jso.pageNum
    msgbox(pageNo)
end if
