javascript - 从 VBA 调用 JavaScript

Question

首先，我不是程序员，我是一名金融专业的学生，​​所以我制作了一个带有宏的 Excel 文件，其中包含 https://www.nseindia.com/products/content/equities/equities/eq_security.htm 的所有字段。会自动填充。但是我无法单击如何单击“以 csv 格式下载文件”。单击链接的 VBA 代码是什么？

Private Sub CommandButton1_Click()
Dim IE As New InternetExplorer
Dim oW As Worksheet: Set oW = ThisWorkbook.Worksheets("Sheet1")
Dim oEleCol As MSHTML.IHTMLElementCollection
Dim oEle As MSHTML.IHTMLElement


With IE
'Set IE = CreateObject("InternetExplorer.Application")

    ' Set IE
    .Visible = True
    'ShowWindow .hwnd, SW_SHOWMAXIMIZED

    ' Navigate to URL
    .Navigate "https://www.nseindia.com/products/content/equities/equities/eq_security.htm"

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Set criteria
    .document.all("symbol").Value = oW.Range("B1")
    .document.all("series").Value = oW.Range("B2")
    .document.getElementById("rdDateToDate").Click

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Set remaining criteria
    .document.all("fromDate").Value = oW.Range("B3")
    .document.all("toDate").Value = oW.Range("D3")

    ' Submit criteria
    .document.getElementById("submitMe").Click

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Find the link to download file
    Set oEleCol = .document.getElementsByTagName("A")
    For Each oEle In oEleCol
        If oEle.innerHTML = "Download file in csv format" Then
            oEleCol.Click
            Exit For
        End If
    Next

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

End With

End Sub

我将 IE 更改为对象并将 oEleCol.Click 固定为 oEle.Click 并且它起作用了。但是它要求确认保存，因此您必须启用自动确认或寻找如何实现 Send Keys

Private Sub CommandButton1_Click()
Dim IE As Object
Dim oW As Worksheet: Set oW = ThisWorkbook.Worksheets("Plan1")
'Dim oEleCol As MSHTML.IHTMLElementCollection
'Dim oEle As MSHTML.IHTMLElement
Set IE = CreateObject("InternetExplorer.Application")

With IE
'Set IE = CreateObject("InternetExplorer.Application")

    ' Set IE
    .Visible = True
    'ShowWindow .hwnd, SW_SHOWMAXIMIZED

    ' Navigate to URL
    .Navigate "https://www.nseindia.com/products/content/equities/equities/eq_security.htm"

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Set criteria
    .document.all("symbol").Value = oW.Range("B1")
    .document.all("series").Value = oW.Range("B2")
    .document.getElementById("rdDateToDate").Click

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Set remaining criteria
    .document.all("fromDate").Value = oW.Range("B3")
    .document.all("toDate").Value = oW.Range("D3")

    ' Submit criteria
    .document.getElementById("submitMe").Click

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

    ' Find the link to download file
    Set oEleCol = .document.getElementsByTagName("A")
    For Each oEle In oEleCol
        If oEle.innerhtml = "Download file in csv format" Then

            oEle.Click
            Exit For
        End If
    Next

    ' Wait for page to be ready
    While .Busy
      DoEvents  'wait until IE is done loading page.
    Wend

End With

End Sub

这种方式适合我。
