我正致力于将多个文件的上传过程自动化到网站。为此，用户必须单击“浏览”按钮并选择文件并单击“打开”。
我尝试使用VBA和VBS复制同样的事情，因为出现“选择要上传的文件”框，VBA代码卡住了所以，使用VBA我创建一个VBS文件，该文件在上载文件框出现之前运行并添加文件名到输入框然后点击ENTER
Public Sub CompleteUploadThread(ByVal fName As String)
Dim strScript As String, sFileName As String, wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
'---Create VBscript String---
strScript = "WScript.Sleep 1500" & vbCrLf & _
"Dim wsh" & vbCrLf & _
"Set wsh = CreateObject(""WScript.Shell"")" & vbCrLf & _
"wsh.SendKeys """ & Trim(fName) & """" & vbCrLf & _
"WScript.Sleep 500" & vbCrLf & _
"wsh.SendKeys ""{ENTER}""" & vbCrLf & _
"WScript.Sleep 500" & vbCrLf & _
"Set wsh = Nothing"
'---Save the VBscript String to file---
sFileName = Application.ActiveWorkbook.path & "\Authorized\zz_automation.vbs"
Open sFileName For Output As #1
Print #1, strScript
Close #1
'---Execute the VBscript file asynchronously---
wsh.run """" & sFileName & """"
Set wsh = Nothing
End Sub
一切都可以正常粘贴文件名，单击打开并关闭对话框。关闭对话框后，VBA需要单击应该触发上载过程的“继续”按钮单击“继续”按钮后，粘贴的文本将消失，并且不会上载任何内容
如果我手动执行相同的过程，它将工作，所以我猜它必须与Sendkeys做一些奇怪的事情
有人可以帮我解决这个问题吗？
下面，请找到我使用上述功能的VBA部分：
CompleteUploadThread el
'el is the filename and path
'click on the Browse button
Call Doc.parentWindow.execScript("document.getElementsByName('filename')[0].click();", "JavaScript")
Dim oHTML_Element As HTMLDDElement
For Each oHTML_Element In Doc.getElementsByTagName("input")
If oHTML_Element.Type = "submit" Then oHTML_Element.Click: Exit For
Next

当你点击“提交”按钮时，也许你需要调用一些js，或者你也可以调用？很难说没有看到页面来源。
