无法使用 VBA 在 Internet Explorer 中输入日期

Question

我有一个加载网页的宏，我必须在该字段中输入一系列日期的开始日期和结束日期。在字段的右侧有一个显示日历（网格）的按钮，您可以在其中单击以选择开始日期和结束日期。

如果我通过 VBA 输入它，它会显示一个消息框“您必须输入选择的日期才能显示 table。” 如果我用按钮输入它，它工作正常。有我的代码：

Sub Sail3()


Dim ie      As Object
Dim frm     As Variant
Dim element As Variant
Dim datesail As String

Set ie = New InternetExplorerMedium


ie.navigate "http://pfrwtekref/websail/"

While ie.readyState <> 4: DoEvents: Wend

Set frm = ie.document.getElementById("Form1")

   ie.Visible = True
   ie.document.getElementById("Form1").elements("txtLogin").Value = ----private
   ie.document.getElementById("Form1").elements("txtPwd").Value = -----------private
   ie.document.getElementById("Form1").elements("Button1").Click
   ie.navigate "http://pfrwtekref/websail/frmSuiviActivite2.aspx"
   
While ie.readyState <> 4: DoEvents: Wend

    ie.document.getElementById("Form1").elements("DateDebut").Value = Date
    ie.document.getElementById("Form1").elements("DateFin").Value = Date
    ie.document.getElementById("Form1").elements("btn_Resultat").Click

End Sub

还有网页截图： -通过 vba（不工作）

-带按钮（工作）点击“Choix3（选择日期）之前的代码

编辑：正如你们中的一些人所说，是的，即使使用“良好”的日期格式它仍然不起作用，我认为这是因为“输入”字段并不是真正用于输入，它们只是显示选定的日期，实际上日期是从日历中获取的。这就是为什么即使使用良好的日期格式，它也会告诉我我没有输入任何日期

Edit2：添加了代码我找不到解决方案，你有什么想法吗？感谢阅读，祝你有美好的一天！（抱歉我的英语不好）

Answer 1

我终于找到解决办法了！！当我按下“Choix”按钮时，会触发一个事件，使此功能出现在代码中

<script type="text/javascript">
<!--
var theForm = document.forms['Form1'];
if (!theForm) {
    theForm = document.Form1;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
// -->
</script>

然后我只需要将值“Calendar1”或“Calendar2”作为 eventTarget 和日期（java 格式）作为 eventArgument 发送到 __doPostBack 函数，就像这样：

Set currentWdw = .document.parentWindow
    With currentWdw
    Application.Wait Now + TimeValue("0:00:01")
    .execScript ("__doPostBack('Calendar1','" & datesail & "')")
    Application.Wait Now + TimeValue("0:00:01")
    .execScript ("__doPostBack('Calendar2','" & datesail & "')")
    End With

这是一个非常具体的案例，但我希望这个答案对以后的人有所帮助。

祝你有个愉快的一天！
