>当我在搜索框中插入几个单词时,它会获取相关数据。我需要从中选择第一个选项。
有一个网站"https://indiarailinfo.com/"当我从电台框中搜索"ADI"时,系统获取名称中包含"ADI"的相关电台?第一个选项始终显示与它非常接近的匹配。如何使用 vba 代码从中选择第一个选项
Dim ie As Object
Set ie = CreateObject("InternetExplorer.Application")
ie.navigate "https://indiarailinfo.com/"
While ie.readyState <> 4: DoEvents: Wend
ie.Visible = True
ie.document.querySelector("[placeholder='from station']").Value = "ADI"
可以从该站点获得 HTML 代码
它在下拉列表中带来第一个答案,例如"ADI/艾哈迈达巴德交界处"我怎样才能在选定的答案中得到这个答案"
敬请建议
自动化纯粹主义者不喜欢使用 javascript 来执行,但我将在这里使用 IE 来触发下拉列表。如果我走纯路线,我会使用硒。
Option Explicit
Public Sub MakeSelection()
Dim ie As InternetExplorer, t As Date, dropdown1 As Object
Set ie = New InternetExplorer
Const MAX_WAIT_SEC As Long = 5
With ie
.Visible = True
.Navigate2 "https://indiarailinfo.com/"
While .Busy Or .readyState < 4: DoEvents: Wend
With .document.querySelector("[placeholder='from station']")
.Focus
.Value = "ADI"
ie.document.parentWindow.execScript "document.querySelector('[placeholder^=from]').click();"
End With
t = Timer
Do
DoEvents
On Error Resume Next
Set dropdown1 = .document.querySelectorAll(".icol span")
On Error GoTo 0
If Timer - t > MAX_WAIT_SEC Then Exit Do
Loop While dropdown1.Length = 0
If dropdown1.Length > 0 Then
dropdown1.item(0).Click
End If
Stop
.Quit
End With
End Sub
