[英]Searching websites using VBA
我想做的是使用VBA搜索網站 ,在左側框中輸入一些單詞,然后在右側獲得結果。
問題是我不了解HTML,也不知道如何引用此框。 我使用GetElementByID
但在行中收到錯誤:
objIE.Document.GetElementByID("text-translation-video-ad").Value = "piłka". "Object doesn't support this property or method".
這是我的代碼:
Sub www()
Set objIE = CreateObject("InternetExplorer.Application")
objIE.Top = 0
objIE.Left = 0
objIE.Width = 800
objIE.Height = 600
objIE.AddressBar = 0
objIE.StatusBar = 0
objIE.Toolbar = 0
objIE.Visible = True
objIE.Navigate ("https://pl.pons.com/tłumaczenie-tekstu")
Do
DoEvents
Loop Until objIE.ReadyState = 4
pagesource = objIE.Document.Body.Outerhtml
objIE.Document.GetElementByID("text-translation-video-ad").Value = "piłka"
objIE.Document.GetElementByID("qKeyboardInputInitiator").Click
Do
DoEvents
Loop Until objIE.ReadyState = 4
End Sub
在不更改任何語言設置的情況下,以下內容翻譯為“ Hello”
碼:
Option Explicit
Public Sub GetInfo()
Dim IE As New InternetExplorer, html As HTMLDocument, translation As String
Const TRANSLATION_STRING As String = "Hello"
With IE
.Visible = True
.navigate "https://pl.pons.com/t%C5%82umaczenie-tekstu"
While .Busy Or .readyState < 4: DoEvents: Wend
Set html = .document
With html
.querySelector("textarea.text-translation-source.source").Value = TRANSLATION_STRING
.querySelector("button.btn.btn-primary.submit").Click
Application.Wait Now + TimeSerial(0, 0, 3)
translation = .querySelector("div.translated_text").innerText
End With
Debug.Print translation
'Quit '<== Remember to quit application
End With
End Sub

Option Explicit
Public Sub GetInfo()
Dim IE As Object, html As Object
With CreateObject("InternetExplorer.Application")
.Visible = True
.navigate "https://pl.pons.com/t%C5%82umaczenie-tekstu"
While .Busy Or .readyState < 4: DoEvents: Wend
Set html = CreateObject("htmlfile")
Set html = .document
With html
.getElementsByClassName("text-translation-source source")(0).innerText = "Translate"
.getElementsByClassName("btn btn-primary submit")(0).Click
Application.Wait Now + TimeSerial(0, 0, 2)
Dim i As Long
For i = 0 To .getElementsByClassName("text-translation-target target").Length - 1
Debug.Print .getElementsByClassName("text-translation-target target")(i).innerText
Next i
Stop
End With
.Quit
End With
End Sub
ID為“ text-translation-video-ad”的元素是不具有.Value
屬性的DIV。 您要訪問提到的DIV的后代的文本區域。
頁面上有2個標簽為“ textarea”的元素,您感興趣的元素是第一個元素,因此為(0)索引。 GetElementsByTagName
標簽必須大寫。
objIE.Document.GetElementsByTagName("TEXTAREA")(0).Value = "piłka"
您還可以從IE自動化中退出,並采取更快,更可靠的方法,而無需使用瀏覽器自動化,這將使您以JSON格式進行響應。 必須設置對Microsoft HTML對象庫的引用。
