【问题描述】：

我正在尝试使用 Powershell 单击“CSV（逗号分隔）”，以便能够保存此报告。

这是下拉菜单背后的代码。

<div class="MenuBarBkGnd" id="ReportViewerControl_ctl09_ctl04_ctl00_Menu" style="display: block; visibility: visible; position: absolute; z-index: 1;">
                                        <div class="DisabledButton">
                                            <a title="XML file with report data" class="ActiveLink" style="padding: 8px 8px 3px; font-family: Verdana; font-size: 8pt; text-decoration: none; display: block; white-space: nowrap;" onclick="$find('ReportViewerControl').exportReport('XML');" href="javascript:void(0)" alt="XML file with report data">XML file with report data</a>
                                        </div><div class="DisabledButton">
                                            <a title="CSV (comma delimited)" class="ActiveLink" style="padding: 8px 8px 3px; font-family: Verdana; font-size: 8pt; text-decoration: none; display: block; white-space: nowrap;" onclick="$find('ReportViewerControl').exportReport('CSV');" href="javascript:void(0)" alt="CSV (comma delimited)">CSV (comma delimited)</a>

                                        </div>
                                    <div style="left: 0px; top: 0px; width: 26px; height: 368px; position: absolute; z-index: -1; opacity: 0.05; background-color: black;"></div></div>

下面的代码会弹出下拉列表。

$DownloadButton = $ie.Document.getElementById('ReportViewerControl_ctl09_ctl04_ctl00_ButtonImgDown')
$DownloadButton.click()

【问题讨论】：

你能贴一些代码吗？
我发布了下拉列表的 html 代码。我不确定您还在寻找什么。
你用 powershell cmd 试过什么？
我尝试过使用 Powershell，但我不知道自己在做什么。
另外，我已经让它与 SendKeys 一起使用，但是这台机器上运行的很多东西会导致它失去焦点，所以我认为 SendKeys 不是最好的选择。

【解决方案1】：

我尝试使用您的代码进行测试。我在单击 CSV（逗号分隔）选项时放置了一条警报消息。因此，当代码单击该特定选项时，它将显示一条警报消息。这表明代码点击了正确的元素。

这里是修改后的 HTML：

<!doctype html>
<html>
<head>
<script>
function abc()
{
    alert("Clicked...");
}
</script>
</head>
<body>
<div class="MenuBarBkGnd" id="ReportViewerControl_ctl09_ctl04_ctl00_Menu" style="display: block; visibility: visible; position: absolute; z-index: 1;">

</body>
</html>

VBA 代码：

Sub demo()

    Dim URL As String
    Dim IE As Object
    Dim i As String

    Set IE = CreateObject("InternetExplorer.Application")


    IE.Visible = True


    URL = "D:\Backup20190913\tests\391.html"


    IE.Navigate URL


    Do While IE.ReadyState = 4: DoEvents: Loop
    Do Until IE.ReadyState = 4: DoEvents: Loop

    i = IE.document.getelementsbytagname("a").Item(1).innerHTML


    If i = "CSV (comma delimited)" Then
        IE.document.getelementsbytagname("a").Item(1).Click

    End If

    Set IE = Nothing


End Sub

此 VBA 代码将找到链接并尝试将其 innerHTML 与静态值匹配。如果匹配，它会点击它。

输出：

此外，您可以尝试根据自己的要求修改代码。如果您有任何问题，可以让我们知道。

【讨论】：

谢谢！这非常有帮助。我觉得我很接近。这就是我现在正在尝试的：$DownloadCSV = $ie.Document.getElementsByTagName('a') | ?{$_.innerHTML -eq "CSV (comma delimited)"} $DownloadCSV.innerText $DownloadCSV.click() 但它不起作用...返回CSV (comma delimited) System.__ComObject
实际上，它成功了！由于昨晚没有活动，该网站已将我注销！你真棒！嗯，你们都很棒！非常感谢！
