vba - 运行时错误 424 需要对象 -- VBA + Internet Explorer = Web 登录

Question

我正在尝试使用 VBA 和 Internet Explorer 登录网站。这会导致运行时间错误 424“需要对象”。
这是我的代码。寻求您的专家建议。

Sub Website()

  Dim IE As Object, Doc As Object, UserName As Object, Password As Object, strCode As String

  Set IE = New InternetExplorerMedium
  IE.Visible = True
  IE.Navigate "http://appln.ABC.com/index.epl"

  Do While IE.ReadyState <> 4: DoEvents: Loop

  Set Doc = IE.Document

  Set UserName = Doc.getElementById("login_usr")
  UserName.Value = "ABCDE"

  Set Password = Doc.getElementById("login_password")
  Password.Value = "ABCDE"

  Set btnLogin = Doc.getElementById("Login")
  btnLogin.Click

End Sub

Answer 1

您是否尝试过本示例中提出的方法？

Fill user name and password in a webpage using VBA

我认为你需要

Set IE = CreateObject("InternetExplorer.Application")

在您的代码中，您实际上并没有创建一个对象，您只是在声明它。

编辑

也许绕过你的 Doc 对象的使用:

Sub Website()

  Dim IE As Object, UserName As Object, Password As Object, strCode As String

  Set IE = New InternetExplorerMedium
  IE.Visible = True
  IE.Navigate "http://appln.ABC.com/index.epl"

  Do While IE.ReadyState <> 4: DoEvents: Loop

  Set UserName = IE.Document.getElementById("login_usr")
  UserName.Value = "ABCDE"

  Set Password = IE.Document.getElementById("login_password")
  Password.Value = "ABCDE"

  Set btnLogin = IE.Document.getElementById("Login")
  btnLogin.Click

End Sub

在链接的示例中，他们只使用了一个对象，看来您不需要为所做的一切创建对象。所以，你可能会逃脱:

Sub Website()

  Dim IE As Object

  Set IE = New InternetExplorerMedium
  IE.Visible = True
  IE.Navigate "http://appln.ABC.com/index.epl"

  Do While IE.ReadyState <> 4: DoEvents: Loop

  With IE.Document
      .getElementById("login_usr").Value = "ABCDE"
      .getElementById("login_password").Value = "ABCDE"
      .getElementById("Login").Click
  End With

End Sub

您还可以为就绪状态添加第二个 do while 循环，如链接示例中所示。
