我有以下内容从网页中提取一些价格和可用性 . 但是我得到了对象:
Set price = ie.Document.querySelector(".price-cont .final-price" )
为什么?
Sub getMetaDataInfo()
Dim ie As New InternetExplorer
Dim mylink As String
Dim wb As Workbook: Set wb = ThisWorkbook
Dim wks As Worksheet
Dim lastrow As Integer
Set wks = wb.Sheets("Info")
Dim i As Integer
lastrow = wks.Cells(Rows.Count, "B").End(xlUp).Row
For i = 2 To lastrow
mylink = wks.Cells([i], 2).Value
ie.Visible = False
ie.Navigate mylink
Do
DoEvents
Loop Until ie.ReadyState = READYSTATE_COMPLETE
Dim price As Object, availability As Object
Set price = ie.Document.querySelector(".price-cont .price")
wks.Cells(i, "C").Value = price.innerText
Set availability = ie.Document.querySelector(".inner-box-one .availability")
wks.Cells(i, "D").Value = availability.innerText
Next i
End Sub
我尝试插入延迟,如下所示
Sub getMetaDataInfo()
Dim IE As New InternetExplorer
Dim mylink As String
Dim wb As Workbook: Set wb = ThisWorkbook
Dim wks As Worksheet
Dim lastrow As Integer
Set wks = wb.Sheets("Info")
Dim i As Integer
lastrow = wks.Cells(Rows.Count, "B").End(xlUp).Row
IE.Visible = True
For i = 2 To lastrow
mylink = wks.Cells(i, 2).Value
IE.Visible = False
IE.Navigate mylink
Dim price As Object, t As Date
Const MAX_WAIT_SEC As Long = 5
Dim price As Object, availability As Object
While IE.Busy Or IE.ReadyState < 4: DoEvents: Wend
t = Timer
Do
DoEvents
On Error Resume Next
Set price = IE.Document.querySelector(".price-cont .final-price")
wks.Cells(i, "C").Value = price.innerText
If Timer - t > MAX_WAIT_SEC Then Exit Do
On Error GoTo 0
Loop
If price Is Nothing Then Exit Sub
Next i
结束子
我的方案是我首先手动登录网页我保持IE窗口打开我去excel运行宏但是..

很难说没有看到HTML / URL . 你验证选择器是否正确?
否则,您现在可以做的主要两件事就是允许有足够的时间加载页面:
1)在尝试选择之前添加适当的等待
2)尝试定时循环以允许进一步的加载时间
3)从
i
