使用VBA和HTML单击自动完成列表中的项
使用VBA和HTML单击自动完成列表中的项
提问于 2020-02-12 07:57:16
我已经创建了一个自动化，它将允许我输入一个网站的细节(虽然我不能分享，因为它是内部的)。我下面的代码只起作用，直到它输入一个关于“收到”的文本。然而，这个“接收自”字段有一个自动完成列表，我需要选择它，以填充其他字段，如TIN和Address。
自动完成列表与https://jqueryui.com/autocomplete/或http://demos.codexworld.com/autocomplete-textbox-using-jquery-php-mysql/中的列表非常相似。
下面是我的代码：
Sub Automate_IE_Enter_Data()
'This will load a webpage in IE
Dim i As Long
Dim Url As String
Dim IE As InternetExplorer
Dim objElement As Object
Dim objCollection As Object
Dim HWNDSrc As Long
Dim wsTemplate As Worksheet
Dim objEvent As Object
Dim li_arr As Variant
Dim NodeList As Object
Dim x As Long
Set wsTemplate = ThisWorkbook.Sheets("Template")
'Create InternetExplorer Object
Set IE = New InternetExplorerMedium
'Set IE.Visible = True to make IE visible, or False for IE to run in the background
IE.Visible = True
'Define URL by getting the value in rngURL; can be found in the main sheet
Url = "http://URL Path"
'Navigate to URL
IE.Navigate Url
' Statusbar let's user know website is loading
Application.StatusBar = Url & " is loading. Please wait..."
Do
DoEvents
Loop Until IE.ReadyState = READYSTATE_COMPLETE
'Webpage Loaded
Application.StatusBar = Url & " Loaded"
'Get Window ID for IE so we can set it as activate window
HWNDSrc = IE.hwnd
'Set IE as Active Window
SetForegroundWindow HWNDSrc
ShowWindow IE.hwnd, SW_SHOWMAXIMIZED
Dim Doc As HTMLDocument
Set Doc = IE.document
inputString = "Nuevo"
With Doc.getElementById("supName")
.Focus
SendKeys inputString 'Trigger the field to show autocomplete list
End With
'----THIS IS WHERE I AM TRYING TO CLICK THE AUTOCOMPLETE LIST THAT IS BEING DISPLAYED-----
'-----HOWEVER, CLICKING DOESN'T SEEM TO WORK.-----
Set NodeList = Doc.querySelectorAll(".ui-active-menuitem[role=""menuitem""]")
For x = 0 To NodeList.Length - 1
'Debug.Print NodeList.Item(x).Click '<==this way
NodeList.Item(x).Focus
NodeList(x).Click '<==Or this method
Next x
MsgBox "Done"
'Unload IE
endmacro:
Set IE = Nothing
Set objElement = Nothing
Set objCollection = Nothing
End Sub下面的是我认为有助于理解我的问题的HTML：

我希望示例页面与您的页面非常相似。我用它来告诉你如何处理这些事情。你脑子里需要想的是一个页面的动态。我已经对宏观作了详细评论。请仔细阅读每一件事来理解它。该解决方案由以下三个部分组成。全部复制到一个模块中。
First:一种使中断时间小于1秒的方法。我们可以使用Windows函数来实现这一点：
'With the following Windows api function we can do breaks less than 1 second
'It works with Excel 32 bit an Excel 64 bit
#If Win64 Then
'For 64 Bit Systems
Public Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As LongPtr)
#Else
'For 32 Bit Systems
Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
#End If第二部分：是通过弹出菜单单击的主要部分。

Dim url As String
Dim browser As Object
Dim nodeInput As Object
Dim nodeUi As Object
Dim nodeLi As Object
Dim countOfLi As Long
Dim controlValue As Long

Dim result As String

'clicked text is now in the input textbox. So we gather all clicks in a string

End Sub第三步：函数以触发HTML。所以您不需要sendkey()
Private Sub TriggerEvent(htmlDocument As Object, htmlElementWithEvent As Object, eventType As String)
Dim theEvent As Object
htmlElementWithEvent.Focus
Set theEvent = htmlDocument.createEvent("HTMLEvents")
theEvent.initEvent eventType, True, False
htmlElementWithEvent.dispatchEvent theEvent

查看LI项是如何包含标记的。你应该试着点击第一个孩子。
而不是：
NodeList.Item(x).Focus
NodeList(x).Click 尝试：
NodeList.Item(x).Focus
NodeList(x).FirstChild.Click 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
