Question

我这里有个情况。我公司有一个网页，可用于创建票证。用户收到电子邮件，他必须根据电子邮件中的信息创建票证。我尝试自动执行此过程，但是卡住了上传附件的过程。

当用户单击附加按钮时，将弹出一个新的弹出窗口，并且我的宏失去了对该弹出窗口的控制。

所以目前正在做什么，保存电子邮件-需要将其附加。使用功能将路径复制到剪贴板运行vb脚本以粘贴并使用发送键输入，延迟5秒点击附加按钮。

因此，在宏单击附加按钮之前，VBS将向后运行以粘贴并按Enter。因此，当弹出窗口打开时，VBS将启动并关闭弹出窗口。

我正在检查要在VB脚本中运行附加功能，这样我就不必单击附加按钮。但是我无法到达任何地方。有人帮忙吗？

以下是网页中可用的功能。我不知道该运行哪个以及如何运行。

这是我使用的VBA代码。

Set IE = New SHDocVw.InternetExplorer
            IE.Visible = True
            
            IE.Navigate "https://sorry cant share the link as per the company policy"
            Do While IE.Busy = True Or IE.READYSTATE <> 4: DoEvents: Loop
        
            Set HTMLDoc = IE.Document
            
    '***************** Save Email

            eachitem.SaveAs StrFile, 3
            
    '***************** file link to clipboard
            CopyText StrFile
                    
    '***************** Attach Email
            HTMLDoc.getElementById("header_add_attachment").Click
            Application.Wait (Now() + TimeValue("00:00:02"))
            
    '***************** Call external VBS file to handle the pop up then attach
            Shell "Explorer.exe " & StrFolderPath & "SNOW.vbs", vbNormalFocus
            HTMLDoc.getElementById("attachFile").Click
            SendKeys "{Enter}", True

我尝试了以下方法来调用该函数，但无济于事！任何援助将不胜感激。我真的不知道哪个功能将文件附加到网站上，以及如何。

Set HTMLDoc1 = IE.Document.parentWindow
        HTMLDoc1.execScript code:="isJEXLExpression(" & StrFile & ")"
        HTMLDoc1.execScript code:="checkAndSetAttachButton()"
        HTMLDoc1.execScript code:="setDeleteButton(this.value)"
        HTMLDoc1.execScript code:="$('attachButton').click()"
        HTMLDoc1.execScript code:="clearAttachmentField($(this).up().up()); setDeleteButton(this.value);"

使用VBA将文件作为附件上传到网页
