无法在网站框架内的InputBox中写入

Question

我们尝试隔离问题，似乎我无法（可能是由于页面中的JavaScript？ - 请查看其他帖子）正确地解决我想要的特定InputBox。 我写的代码：

Sub AddInfoFromIntranet()

Dim Ie As SHDocVw.InternetExplorer
Dim Doc As MSHTML.HTMLDocument
Dim Elements As MSHTML.IHTMLElementCollection

    Set Ie = New SHDocVw.InternetExplorer
    With Ie
        .navigate "[HERE GOES MY WEBSITE]"
        .Visible = True

        Do Until Not .Busy And .readyState = 4
            DoEvents
        Loop

        Set Doc = .document
        Set Elements = Doc.getElementsByName("Nachnamevalue")

        .Quit
    End With

    Set Ie = Nothing

End Sub

“Nachnamevalue”是网页“top_window”框架中包含的元素的名称：

框架的HTML

上面的图片是我打开我想要的地址，按F12并点击所需输入框上的“选择项目”项目。 在一开始，页面只是一堆javascripts（打开页面 - F12并复制DOM资源管理器的内容）

现在，如果我试着看看我的“Elements”变量是什么，我得到的对象基本上是空的。

空对象

如果相反我写：

Set Elements = Doc.getElementsByName("top_window")

有东西可以找到。 不幸的是我在INTRANET页面上工作，所以我无法为你提供地址。

您遇到的问题是，当您的目标输入框'Nachnamevalue'位于IFrame内部时，IE必须先导航到目标页面，然后再导航到IFrame 。

如果没有到IFrame导航，那么DOM不包含IFrame内部的元素，这就是它无法工作的原因。 HTH

（示例代码使用位于我的PC上的文件，因此将url替换为来自Intranet的实际URL以及带有实际页面名称的'main.html'的名称。）

Option Explicit

' Add reference to Microsoft Internet Controls (SHDocVw)
' Add reference to Microsoft HTML Object Library

Sub AddInfoFromIntranet()

    Dim ie As SHDocVw.InternetExplorer
    Dim doc As MSHTML.HTMLDocument
    Dim url As String

    ' Navigate to main page first
    url = "file:///c:/temp/Noldor/"
    Set ie = New SHDocVw.InternetExplorer
    ie.Visible = True
    ie.navigate url & "main.html"

    While ie.Busy Or ie.readyState <> READYSTATE_COMPLETE: DoEvents: Wend

    Dim inputs As MSHTML.IHTMLElementCollection
    Dim iFrames As MSHTML.IHTMLElementCollection
    Dim iFrame As MSHTML.HTMLFrameElement

    ' Get top_window frame and navigate to it then
    Set doc = ie.document
    Set iFrames = doc.getElementsByName("top_window")

    If Not iFrames Is Nothing Then
        Set iFrame = iFrames(0)
        ie.navigate url & iFrame.src

        While ie.Busy Or ie.readyState <> READYSTATE_COMPLETE: DoEvents: Wend

        Set inputs = doc.getElementsByName("Nachnamevalue")
        If Not inputs Is Nothing Then
            inputs(0).Value = "Test123"
        End If
    End If

    ie.Quit
    Set ie = Nothing
End Sub

main.html示例HTML：

<html>
<head>

<frameset cols="" rows="">
  <frame name="top_window" src="top_window.html" />
</frameset>
<noframes>
<!-- no frames content here -->
