网页上的复选框使用 Excel VBA

Question

我正在尝试使用 Excel VBA 检查网页上的复选框。我的代码不起作用。（没有报错但是打勾了）

如何在网页上显示勾号？

我在网络抓取方面做错了吗？

    Dim ie As Object
    Set ie = CreateObject("internetexplorer.application")
    With ie
        .Visible = True
        .navigate "link"

        Do While .busy

    ie.document.all("searchBy").Value = "PURCHASE_ORDER"
    ie.document.all("purchaseOrderNumber").Value = ThisWorkbook.Sheets("Data").Cells(1, 2).Text
    ie.document.getelementbyid("create-invoice-search-submit").Click

HTML:

Answer 1

您要查找的元素位于表单内的 iframe 内。你必须和他们谈判。我已经从文件中读取了您的 html。

您需要的位是：

ie.document.getElementsByTagName("iframe")(0).document.getElementsByTagName("input")(4).Click

表单和 iframe：

我的代码：

Option Explicit
Public Sub test()
    Dim oFSO As Object, oFS As Object, sText As String
    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFS = oFSO.OpenTextFile("C:\Users\User\Desktop\doc.html")

    Do Until oFS.AtEndOfStream
        sText = oFS.ReadAll()
    Loop

    Dim html As New HTMLDocument, b As Object
    html.body.innerHTML = sText
    Set b = html.getElementsByTagName("iframe")(0).document.getElementsByTagName("input")(4)
    Debug.Print b.outerHTML
    b.Click
End Sub

正在验证正确的元素：

所选元素外层window的打印输出HTML表明选择了正确的元素：

确保每次点击后加载页面

使用

While IE.Busy Or IE.readyState < 4: DoEvents: Wend

在每次单击事件后允许加载页面。这包括在尝试此点击之前您在登录序列中进行的点击之后。
