使用 powershell 进行 web ui 自动化。出现异常：invoke 方法失败，因为 [System.__ComObject] 不包含“click”方法。
可以点击提交类型输入吗？
我使用 getElementsByTagName getElementsByClassName getElementsByName ，不起作用。
任何人都可以帮助我吗？
powershell代码如下：
# open the specified web site and commit the key
$ie = new-object -com "InternetExplorer.Application"
$ie.navigate("http://gitlab.alibaba-inc.com/keys/new")
$ie.visible = $true
while($ie.busy) {sleep 1}
$doc = $ie.document
# commit the button
$commit = $doc.getElementsByTagName("commit")
if($commit)
{$commit.click()}
html源代码如下：
