html - 使用 VBA 和 HTML 单击自动完成列表中的项目

Question

我创建了一个自动化程序，它允许我在网站上输入详细信息(尽管我无法共享它，因为它是内部的)。我下面的代码仅在输入“接收自”文本之前有效。但是，这个“接收自”字段有一个自动完成列表，我需要选择它才能填充其他字段，例如 TIN 和地址。

自动完成列表与
https://jqueryui.com/autocomplete/
或 http://demos.codexworld.com/autocomplete-textbox-using-jquery-php-mysql/

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

以下是我认为有助于理解我的问题的 HTML:

好问题!

使用 jQuery 自定义控件时，Internet Explorer 可能很难使用内置方法实现自动化。值得庆幸的是，有一种方法可以将 JavaScript 注入(inject)浏览器以使用这些控件的现有方法，或者使用 jQuery 本身(当加载到页面上时)使生活变得更加轻松。

我在下面所做的是使用 this页面作为测试的替身，上面有一个自动完成控件。

您可能需要对 CSS selectors 进行更改指向页面上的正确元素，但下面使用的方法应该可以以编程方式控制您想要的元素。

代码

Option Explicit

#If Win64 Then
    Public Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As LongPtr)
#Else
    Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
#End If

Sub AutoCompleteExamples()
    Dim ie As Object: Set ie = CreateObject("InternetExplorer.Application")
    ie.Visible = True
    LoadPage ie, "https://jqueryui.com/resources/demos/autocomplete/default.html"

    'Trigger autocomplete with jQuery. This select the first ui-autocomplete-input, you may need -
    'to adjust this, if this isn't the first autocomplete control on page
    ie.document.parentWindow.execScript "$('.ui-autocomplete-input').first().val('A').autocomplete('search')"

    'Select first item with jQuery, the UL updates in response to the click event
    'Result should be it selected 'ActionScript'
    ie.document.parentWindow.execScript "$('ul.ui-menu').children().first().click()"

    'Alternatively if you want to pick an item from the drop down with a specific value
    'You can look inside the ul-menu-items that are created and use Contains. The contains method is case sensitive
    ie.document.parentWindow.execScript "$('ul.ui-menu').children().find('.ui-menu-item-wrapper:contains(""ActionScript"")').click()"
End Sub

Public Sub LoadPage(ByRef ie As Object, ByVal URL As String)
    With ie
        .Navigate URL
        Sleep 500 'Add a built in delay
        Do While .busy And .readystate <> 4: DoEvents: Loop
        Sleep 500 'Add a built in delay
    End With
End Sub
