我需要遍历特定网站的下拉列表并下载每个条目的最新文件。我设法打开网站并单击“提交”按钮,但我找不到循环浏览所有下拉条目的解决方案。
Dim reportnr As String
Dim internetadress As String
Dim btn As Object
Dim IE As SHDocVw.InternetExplorer
reportnr = 10
internetadress = adress & reportnr
Set IE = CreateObject('InternetExplorer.Application')
IE.Visible = True
IE.navigate internetadress
Do While IE.Busy
Application.Wait DateAdd("s", 2, Now)
Loop
While IE.Busy
DoEvents
Wend
For Each btn In IE.document.getElementsByClassName("btn btn-primary")
If btn.name = "submit" Then
btn.Click
End If
Next btn
网站上关于下拉菜单的代码。
我尝试了几种方法,但会出错或什么也没有发生。我尝试的最后一件事是:
Option Explicit
'VBE > Tools > References:
' Microsoft Internet Controls
Public Sub SelectQuantity()
Dim ie As New InternetExplorer, numberOfOptions As Long, i As Long
With ie
.Visible = True

While .Busy Or .readyState < 4: DoEvents: Wend
With .document
numberOfOptions = .querySelectorAll("#quantity option").Length 'gather option tag element children of parent select element with id quantity
For i = 1 To numberOfOptions
.querySelector("#quantity [value='" & i & "']").Selected = True
ActiveSheet.Cells(i, 1) = i
Next
Stop
End With
End With
End Sub

预先感谢您的帮助。

从您提供的网站,您可以尝试使用以下代码循环下拉列表以选择您想要的选项:
Set lists = IE.document.getElementsByClassName("active-result") 'get all the options li elements
For Each liElement In lists
If liElement.innerText = "something" Then
liElement.setAttribute "class", "active-result result-selected"
End If
Next liElement
我发现所选择的选项有不同的类,即 active-result result-selected
,所以我想也许您可以更改类以选择该选项。
