我正在尝试创建一个从网站上提取报告的宏,它有四个下拉列表来选择值。 我可以登录该页面并将自己定向到报告页面,但出于某种原因我遇到了下拉列表的问题。我尝试了几种解决方案'这是在线提供的,但我不断收到错误消息:

  

运行时错误'':对象不支持此属性或方法。

以下是可供选择的下拉列表之一:

<select name="LocationID">
<option value="0" selected="">All Location</option>
<option value="9">Atlanta</option>
<option value="7">Denver</option>
<option value="3">Las Vegas</option>
<option value="1">Los Angeles</option>
<option value="4">Miami</option>
<option value="6">New Jersey</option>
<option value="10">Phoenix</option>
<option value="2">San Francisco</option>
<option value="8">Seattle</option>
<option value="11">Vancouver</option>
</select>

以下是我目前在VBA中所拥有的内容:

Option Explicit
Const MyUserID As String = "test123"
Const MyPassword As String = "test123"
Const READYSTATE_COMPLETE As Integer = 4
Dim objIE As Object


Public Sub LoginScript()

Set objIE = CreateObject("InternetExplorer.Application")

With objIE
.Visible = True
.Silent = True
.navigate ("https://wwww.mywebsite.com")
Do Until .readyState = READYSTATE_COMPLETE
DoEvents
Loop
Application.Wait Now() + TimeValue("00:00:02")
.document.all.txtuserid.Value = MyUserID
.document.all.txtPassword.Value = MyPassword
objIE.document.getElementsByName("btnSubmit")(0).Click
Do Until .readyState = READYSTATE_COMPLETE
DoEvents
Loop
Application.Wait Now() + TimeValue("00:00:02")
.navigate("https://www.mywebsite.com/sample.html")
Do Until .readyState = READYSTATE_COMPLETE
DoEvents
Loop
.document.getElementByName("LocationID").Value = "7"
objIE.document.getElementsByName("view")(0).Click
End With
End Sub

我假设您在此行收到错误消息?

.document.getElementByName("LocationID").Value = "7"

那是因为Name是一个元素集合。与ID(getElementByID)不同,集合上的元素是复数。

在这种情况下,正确的语法是:

.document.getElementsByName("LocationID")(0).Value = "7"

注意附加的(0)?这是因为它又是一个集合,因此您还需要选择集合项。 (可能不一定是(0),但如果不查看整个HTML代码,我无法确定。但

它应该是这样的......

Sub passValueToComboBox1()
   Dim ie  As Object
   Dim oHTML_Element As IHTMLElement

   Set ie = CreateObject("InternetExplorer.Application")
   ie.Visible = True
   ie.navigate "http://www.your_web_site.com"
   While ie.Busy Or ie.readyState <> 4: DoEvents: Wend

   Set oHTML_Element = ie.document.getElementsByName("selectedReportClass")(0)
   If Not oHTML_Element Is Nothing Then oHTML_Element.Value = "com.db.moap.report.FUBU"

   For Each oHTML_Element In ie.document.getElementsByTagName("input")
      If oHTML_Element.Type = "submit" Then oHTML_Element.Click: Exit For
   Next
End Sub
