【问题描述】:
关于修改一段代码以获取其他网页表格内容的快速问题。关于如何根据标题获取某些表格内容,我在这里获得了一些很好的指导,并且效果很好 - 再次感谢 'QHarr',他非常乐于助人。
我想要获取表格详细信息的 URL 是:
https://finance.yahoo.com/quote/AAPL/?p=AAPL
这是获取我想要的数据的一段代码:
Sub GetYahooInfo100()
Dim tickers(), ticker As Long, lastRow As Long, headers()
Dim wsSource As Worksheet, http As clsHTTP, html As HTMLDocument
Application.ScreenUpdating = False
Set wsSource = ThisWorkbook.Worksheets("100")
Set http = New clsHTTP
headers = Array("Ticker", "Previous Close", "Open", "Bid", "Ask", "Day's Range", "52 Week Range", "Volume", "Avg. Volume", "Market Cap", "Beta", "PE Ratio (TTM)", "EPS (TTM)", _
"Earnings Date", "Forward Dividend & Yield", "Ex-Dividend Date", "1y Target Est")
With wsSource
lastRow = GetLastRow(wsSource, 1)
Select Case lastRow
Case Is < 3
Exit Sub
Case 3
ReDim tickers(1, 1): tickers(1, 1) = .Range("A3").Value
Case Is > 3
tickers = .Range("A3:A" & lastRow).Value
End Select
ReDim Results(0 To UBound(tickers, 1) - 1)
Dim i As Long, endPoint As Long
endPoint = UBound(headers)
For ticker = LBound(tickers, 1) To UBound(tickers, 1)
If Not IsEmpty(tickers(ticker, 1)) Then
Set html = http.GetHTMLDoc("https://finance.yahoo.com/quote/" & tickers(ticker, 1) & "/?p=" & tickers(ticker, 1))
Results(ticker - 1) = http.GetInfo(html, endPoint)
On Error Resume Next
Set html = Nothing
Else
Results(ticker) = vbNullString
End If
Next
.Cells(2, 1).Resize(1, UBound(headers) + 1) = headers
For i = LBound(Results) To UBound(Results)
.Cells(3 + i, 2).Resize(1, endPoint - 1) = Results(i)
Next
End With
Application.ScreenUpdating = True
End Sub
下面还有一段:
Public Function GetLastRow(ByVal ws As Worksheet, Optional ByVal columnNumber As Long = 1) As Long
With ws
GetLastRow = .Cells(.Rows.Count, columnNumber).End(xlUp).Row
End With
结束函数
就像我说的,这里的一位成员非常有助于确定如何做到这一点。我已经尝试修改这段代码以从统计页面中获取另一组数据,如下:
https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL
但我一定错过了什么。除非我对表格的引用不正确,否则我会不知所措。我正在查看是否可以捕获每个表中的所有数据字段,而不仅仅是我可能出错的一个。
希望有人能提供帮助。
非常感谢。
【问题讨论】:
-
你从新的 url 得到什么? finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL所有表?
-
所有的桌子都很棒!如果可以的话。我使用原始代码尝试了不同的引用,但我遗漏了什么?
