如何自动检查从excel加载的多个网站时间？

Question

我在excel中有大约100个网站，我需要检查网站加载的时间。 目前，我是通过逐个使用开发人员工具（F12） >网络 >拍摄（列）在Internet Explorer中手动执行此操作。 有没有办法自动检查？

不确定你的VBA水平，这远非完美，但作为一个起点，这是我通常用来刮网站的代码，但我稍微修改了每个网站打开需要多长时间。 这假设您在A列中拥有所有网站，它将打印在B列中打开网站所用的时间。 请记住，这是宏每个网站运行时间的时间，因此不能完全准确地确定实际站点加载的时间。

Enum READYSTATE
READYSTATE_UNINITIALIZED = 0
READYSTATE_LOADING = 1
READYSTATE_LOADED = 2
READYSTATE_INTERACTIVE = 3
READYSTATE_COMPLETE = 4
End Enum

Sub ImportWebsiteDate()
'to refer to the running copy of Internet Explorer
Dim ie As InternetExplorer, WDApp As Object, staTime As Double, elapsedTime As Double

'to refer to the HTML document returned
Dim html As HTMLDocument, websiteNo As Integer, curSite As String
    websiteNo = Range("A500").End(xlUp).Row
'open Internet Explorer in memory, and go to website

Set ie = New InternetExplorer

For i = 1 To websiteNo
    curSite = Cells(i, 1).Value
    ie.Visible = False
    staTime = Timer
    ie.navigate curSite

    'Wait until IE is done loading page
    Do While ie.READYSTATE <> READYSTATE_COMPLETE
    Application.StatusBar = "Trying to go to " & curSite
    DoEvents
    Loop
    elapsedTime = Round(Timer - staTime, 2)
    Cells(i, 2).Value = elapsedTime
Next i
Set ie = Nothing
Application.StatusBar = False
Application.ScreenUpdating = False
End Sub
