Question

如何更改Customer下拉菜单的选项（如下面的HTML示例所示），然后单击“提交”？

我需要将所选值更改为：

Diamond State Generation Partner (Brookside) (LVG- QFTP-RC)

收件人

Diamond State Generation Partners (Red Lion) (LVG- QFTP-RC)

，然后单击提交。

尝试：

我的尝试如下所示。

在以下行上：

   MyBrowser.document.querySelector("option[value=1745]").Selected = True

产生的错误

“运行时错误'-2147352319（80020101）'：方法'querySelector'的对象“ JScriptTypeInfo”失败。

代码：

Sub daily()
    Dim HMTLDoc As HTMLDocument
    Dim MyBrowser As InternetExplorer
    Dim MyHTML_Element As IHTMLElement
    Dim MYURL As String
    '  website
    MYURL = "website"
    Set MyBrowser = New InternetExplorer
    MyBrowser.Silent = True
    MyBrowser.navigate MYURL
    MyBrowser.Visible = True
    Do
    Loop Until MyBrowser.readyState = READYSTATE_COMPLETE
    Set HTMLDoc = MyBrowser.document
    ' user login and password
    HTMLDoc.all.user_login.Value = "username"
    HTMLDoc.all.user_password.Value = "password"
    HTMLDoc.forms(0).submit
    While MyBrowser.Busy Or MyBrowser.readyState < 4: DoEvents: Wend
    ' click reports
    HTMLDoc.getElementsByClassName("menuitem")(1).Click
    While MyBrowser.Busy Or MyBrowser.readyState < 4: DoEvents: Wend
    'click Billing Analysis Report (Industrial)
    HTMLDoc.getElementsByClassName("firstlink")(0).Click
    'click to submit to get to billing analysis report
     With MyBrowser.document
    .querySelector("select[name=vsCustKy]").Click
     'I receive the error message on the next line below
    .querySelector("option[value=1745]").Selected = True
   .querySelector("select[name=vsCustKy]").FireEvent "onchange"
     End With
    HTMLDoc.forms(0).submit

End Sub

Answer 1

该错误是由于缺少用于数字的''引起的。还有一种导航形式。

MyBrowser.document.getElementsByTagName("form")(0).querySelector("option[value='1745']").Selected = True

在尝试选择之前，您可能需要确保等待。传统上是

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

良好状态之前和任何点击事件之后。

您还可以使用循环来等待元素存在，直到超时。

Const WAIT_TIME_SECS As Long = 5
Dim t As Date, ele As Object
t = Timer

Do
    DoEvents
    On Error Resume Next
    Set ele = MyBrowser.document.getElementsByTagName("form")(0).querySelector("option[value='1745']").
    On Error GoTo 0
    If Timer - t > WAIT_TIME_SECS Then Exit Do
Loop While ele Is Nothing
If Not ele Is Nothing Then ele.Selected = True

Answer 2

尝试一下：

Set dropOptions = HTMLDoc.getElementsByTagName("select")
For Each op In dropOptions
    If op.getAttribute("name") = "vsCustKy" Then
        op.Value = 1745
        Exit For
    End If
Next op

从vba的下拉框中选择各种选项
