我已经在Microsoft Excel中创建了VBA代码。 我想要的代码是：
我有下面的代码，这种工作方式。它使用Internet Explorer，因为该网站无法与google chrome一起正常运行，但我会尝试一下，如果效果更好。
代码确实导航，没有打开选项卡...该代码不执行的操作是开始使用新页面/选项卡中的数据，所有元素均来自根页面。我尝试通过item(1)选择一个新的IE实例。我不确定要使instancehyperlinks引用新创建的选项卡需要做什么。仅供参考，由于根网站的编写方式，数据显示在新标签中，我无法控制任何HTML。
代码如下：
Sub getalllinks()
Dim ie As Object
Set ie = CreateObject("InternetExplorer.Application")
ie.Visible = True
url_name = "123.123.123.123"
ie.navigate url_name
Do
DoEvents
Loop Until ie.readystate = 4 ' wait until fully loaded
Set allhyperlinks = ie.document.getelementsbytagname("A")
For Each hyper_link In allhyperlinks
If hyper_link.Title = "View Subject" Then
hyper_link.Click
Do
DoEvents
Loop Until ie.readystate = 4 ' wait until fully loaded
Set instancehyperlinks = ie.document.getelementsbytagname("A")
For Each hyper_linkPage In instancehyperlinks
If hyper_linkPage.Title = "Download" Then
hyper_linkPage.Click
End If
Next
End If
Next
End Sub

好吧，我之前遇到过这个问题并已解决，而不必使用任何硒等第三方工具，在得到答案之前，我先给你提个建议：用VBA自动化IE是一个严重的PITA ，如果可能的话，我会考虑其他途径。
免责声明：我从其他来源中发现并修改了很多此类代码，由于许多原因，我现在无法追踪该来源，如果找到它们，我将在以后添加它们。
好吧，首先，您需要找到窗口，创建一个新模块，并将其命名为“ modWindowsAPI”，并将其添加到其中，这将使您的脚本能够钩接到必要的Windows API中，不仅可以找到窗口，还可以将其下载为好吧：
Option Explicit
Public Declare Sub Sleep Lib "kernel32" _
(ByVal dwMilliseconds As Long)
Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Public Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" _
(ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Public Declare Function SetForegroundWindow Lib "user32" _
(ByVal hWnd As Long) As Long
Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
(ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Declare Function SendMessageByString Lib "user32" Alias "SendMessageA" _
(ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long
Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" _
(ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Declare Sub keybd_event Lib "user32" _
(ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Public Const BM_CLICK = &HF5
Public Const WM_SETTEXT = &HC
Public Const WM_GETTEXT = &HD
Public Const WM_GETTEXTLENGTH = &HE
Public Const VK_KEYDOWN = &H0
Public Const VK_KEYUP = &H2
Public Const VK_CONTROL = &H11
从这里开始，有两种方法可以锁定窗口（据我所知，可能还有更多），可以通过URL或窗口标题来找到它。
按URL查找窗口： 创建函数GetOpenIEByTitle：
Function GetOpenIEByTitle(i_Title As String, Optional ByVal i_ExactMatch As Boolean = True) As SHDocVw.InternetExplorer
Dim windowMatched As Boolean
Dim e_title As String
windowMatched = False
Dim windowTimeout As Integer
windowTimeout = 0
Do Until windowMatched = True Or windowTimeout = 10
If i_ExactMatch = False Then i_Title = "*" & i_Title & "*"
'ignore errors when accessing the document property
On Error Resume Next
'loop over all Shell-Windows
For Each GetOpenIEByTitle In objShellWindows
'if the document is of type HTMLDocument, it is an IE window
If TypeName(GetOpenIEByTitle.Document) = "HTMLDocument" Then
'check the title
If GetOpenIEByTitle.Document.Title Like i_Title Then
'leave and set boolean as true, we found the right window
windowMatched = True
Sleep 600
Exit Function
End If
End If
Next
windowTimeout = windowTimeout + 1
Loop
End Function
按URL查找窗口： 创建名为GetOpenIEByURL的函数
Function GetOpenIEByURL(ByVal i_URL As String) As SHDocVw.InternetExplorer
Dim urlMatched As Boolean
urlMatched = False
Dim urlTimeout As Integer
urlTimeout = 0
Do Until urlMatched = True Or urlTimeout = 30
Dim objShellWindows As New SHDocVw.ShellWindows
'ignore errors when accessing the document property
On Error Resume Next
'loop over all Shell-Windows
For Each GetOpenIEByURL In objShellWindows
'if the document is of type HTMLDocument, it is an IE window
If TypeName(GetOpenIEByURL.Document) = "HTMLDocument" Then
'check the URL
If GetOpenIEByURL.Document.URL = i_URL Then
'leave, we found the right window
urlMatched = True
Exit Function
End If
End If
Next
urlTimeout = urlTimeout + 1
Loop
End Function
总结 您处在正确的位置，需要多个IE对象，每个活动窗口都需要一个自己的对象，如果关闭它并转到下一个对象，则可以重用同一对象。
调用上述方法之一，如下所示：
Set ieAppChild = GetOpenIEByTitle("Some Title", False)
Set ieAppChild = GetOpenIEByURL("https://127.0.0.1")
编辑：忘记提及当您准备关闭IE窗口以移至下一个窗口时，请不要忘记调用ieAppChild.Quit，并且不必在重用之前将ie子对象设置为no，但是，这不是最佳实践。
最后是找到下载窗口并单击保存的功能：
Function SaveAs()
Dim hWnd As Long
Dim timeout As Date
'Debug.Print "File_Download_Click_Save"
'Find the File Download window, waiting a maximum of 30 seconds for it to appear
timeout = Now + TimeValue("00:00:30")
Do
hWnd = FindWindow("#32770", "File Download")
DoEvents
Sleep 200
Loop Until hWnd Or Now > timeout
'Debug.Print " File Download window "; Hex(hWnd)
If hWnd Then
'Find the child Save button
hWnd = FindWindowEx(hWnd, 0, "Button", "&Save")
'Debug.Print " Save button "; Hex(hWnd)
End If
If hWnd Then
'Click the Save button
SetForegroundWindow (hWnd)
Sleep 600 'this sleep is required and 600 miiliseconds seems to be the minimum that works
SendMessage hWnd, BM_CLICK, 0, 0
End If
End Function

感谢user1090660 我的解决方法是将其制作成两步脚本，首先，我将第一页中的所有链接收集到Excel工作表中 关闭互联网浏览器 然后为Excel工作表中的每个链接重新打开Internet Explorer 然后，我进入了正确的页面并可以挖掘数据。 我的方式远不及您的方式优雅或可扩展，但它确实有效， 感谢您的回答。 马丁
