我建议尝试使用下面的代码示例进行测试可能有助于解决问题。

Sub demo()

    Dim URL As String
    Dim IE As Object
    Dim element As HTMLInputElement
    Set IE = CreateObject("InternetExplorer.Application")
   
    IE.Visible = True
    
    URL = "YOUR WEB PAGE ADDRESS HERE" 'Add your site address here....
 
    IE.navigate URL

    Do While IE.Busy
        Application.Wait DateAdd("s", 1, Now)
    Loop
    Application.Wait DateAdd("s", 2, Now)
    Set element = IE.document.querySelector("[class='shopee-searchbar-input__input']")
    element.removeAttribute ("aria-label")
    element.removeAttribute ("placeholder")
    element.Value = "abc"
    element.FireEvent ("OnChange")
    Set IE = Nothing
   
End Sub

输出：

此外，您可以根据需要修改代码示例。
