在我最初的帖子中，我解释了如何触发事件。现在我也解释如何单击“上传照片”按钮并聚焦弹出窗口。
现在的问题是，所需的 html 文档位于我无法访问的 iframe 中。我知道可能有不同的原因，但它们都不能解决问题。
这就是我现在所拥有的：
Sub SelectColorForGolfballs()
Dim objShell As Object
Dim objWindow As Object
Dim browser As Object
Dim url As String
Dim nodeColorDropDown As Object
Dim nodeThreeButtons As Object
Dim browserPopUp As Object
Dim nodeFrames As Object
Dim nodeIframeDoc As Object
Set objShell = CreateObject("Shell.Application")
url = "https://www.golfballs.com/Golf-Misc/Tools/Classic-Photo-Poker-Chips-3-Pack.htm"
'Initialize Internet Explorer, set visibility,
'call URL and wait until page is fully loaded
Set browser = CreateObject("internetexplorer.application")
browser.Visible = True
browser.navigate url
Do Until browser.ReadyState = 4: DoEvents: Loop
'Select color from dropdown
Set nodeColorDropDown = browser.document.getElementByID("2")
nodeColorDropDown.selectedIndex = 6 'Pink for testing
Call TriggerEvent(browser.document, nodeColorDropDown, "change")
'Manual break for loading the page complitly
'Application.Wait (Now + TimeSerial(pause_hours, pause_minutes, pause_seconds))
Application.Wait (Now + TimeSerial(0, 0, 2))
'Open Picture Upload
'The document changed, so you can't work with the old document here
'In a first step you need the div element with the three buttons
'we get in the last step by trigger dropdown event
'
'<div class="options-gallery">
' <a href="javascript:productSelection(1, 'P');">
' <img src="https://d1tp32r8b76g0z.cloudfront.net/images/property/button/Half/Condition_P.jpg" title="Personalized" border="0">
' </a>
' <a href="javascript:productSelection(1, 'S');">
' <img src="https://d1tp32r8b76g0z.cloudfront.net/images/property/button/Half/Condition_S.jpg" title="Photo" border="0">
' </a>
' <a href="javascript:productSelection(1, 'L');">
' <img src="https://d1tp32r8b76g0z.cloudfront.net/images/property/button/Half/Condition_L.jpg" title="Novelty" border="0">
' </a>
'</div>
Set nodeThreeButtons = browser.document.getElementsByClassName("options-gallery")(0)
'The second button must be clicked
nodeThreeButtons.FirstChild.NextSibling.Click
Application.Wait (Now + TimeSerial(0, 0, 2))
'Focus popup by runnig throuhg all open windows
For Each objWindow In objShell.Windows
'Check if it's an IE
If InStr(1, UCase(objWindow.FullName), "IEXPLORE") > 0 Then
'Check if it's the right IE
If InStr(1, objWindow.document.getElementsByTagName("title")(0).innertext, "iCusomize Image Selection") Then
Set browserPopUp = objWindow
Exit For
End If
End If
Next objWindow
'Now we can work with the popup
'It has only short code over all and a very short body
'You have to access the content of an iFrame
'
'Problem: I don't know why the following don't work
'I know it can't be in the same line
'You must split the access to the iFrame
'Get a node collection of all frames/ iframes of the document
Set nodeFrames = browserPopUp.document.frames
'The following line couses the error "Access denied"
'Select the first (and only) frame from the node collection
Set nodeIframeDoc = nodeFrames(0).document
'Check the copyright checkbox
nodeIframeDoc.getElementByID("copyright_check").Click
'If you are at this point we can look ahead
End Sub
这个程序触发你需要的事件：
Private Sub TriggerEvent(htmlDocument As Object, htmlElementWithEvent As Object, eventType As String)
Dim theEvent As Object
htmlElementWithEvent.Focus
Set theEvent = htmlDocument.createEvent("HTMLEvents")
theEvent.initEvent eventType, True, False
htmlElementWithEvent.dispatchEvent theEvent
End Sub
