Question

我正在尝试使用VBA脚本excel宏link从网站下载数据，但我感兴趣的数据驻留在网页框架中，主页面的网址和框架没有得到更改

以下是适用于主页的宏，请帮我从网页框架中下载。

 'Microsoft HTML Office Library
Sub webtable_NSE()
    Dim HTMLDoc As New HTMLDocument
    Dim objElementsTd As Object
    Dim objTd As Object
    Dim lRow As Long
    Dim myarray()
    Dim oIE As InternetExplorer
    Set oIE = New InternetExplorer
    oIE.navigate "https://www.nseindia.com/products/content/equities/ipos/ipo_current_quess.htm"

    'javascript:loadIpoBidDetails('/products/content/equities/ipos/Quess_curr_ipo_bid_details.htm')
    'oIE.Navigate "https://www.nseindia.com/products/content/equities/ipos/Quess_curr_ipo_bid_details.htm"

    Do Until (oIE.readyState = 4 And Not oIE.Busy)
        DoEvents
    Loop

    Application.Wait (Now + TimeValue("0:00:03"))
    HTMLDoc.body.innerHTML = oIE.Document.body.innerHTML
    With HTMLDoc.body
        Set elemcollection = .getElementsByTagName("Table")
        For t = 0 To elemcollection.Length - 1
            For r = 0 To elemcollection(t).Rows.Length - 1
                For c = 0 To elemcollection(t).Rows(r).Cells.Length - 1
                    ThisWorkbook.Sheets("NSE").Cells(ActRw + r + 1, c + 1) = elemcollection(t).Rows(r).Cells(c).innerText
                Next c
            Next r
            ActRw = ActRw + elemcollection(t).Rows.Length + 1
        Next t
    End With
    oIE.Quit
End Sub

Answer 1

如果没有VBA，你可以做你想做的事。

在“数据”标签中，您可以点击“来自网络，地址：https://www.nseindia.com/products/content/equities/ipos/QUESS_curr_ipo_bid_details.htm”，然后点击“导入”。之后，您可以将连接属性更改为“打开文件时刷新数据”或控制何时使用VBA刷新数据

如果你知道包含你想要的表格数据的网址，你就不必尝试自动化IE以“到达那里”。 - 您只需针对该特定URL发送HTTP请求即可。您正在寻找的库是MSXML2 XMLHTTP - 这是返回数据的代码示例：

Option Explicit

Sub GetTableData()

    Dim objRequest As Object
    Dim strUrl As String
    Dim strHtml As String
    Dim blnAsync As Boolean

    Set objRequest = CreateObject("MSXML2.XMLHTTP")
    strUrl = "https://www.nseindia.com/products/content/equities/ipos/QUESS_curr_ipo_bid_details.htm"
    blnAsync = True

    With objRequest
        .Open "GET", strUrl, blnAsync
        .Send
        While .readyState <> 4
            DoEvents
        Wend
        strHtml = .responseText
    End With

    Debug.Print strHtml

End Sub
