Powershell、ie9 和 getElementById
我成功地使用此网站的 Web 自动化脚本： heise Web 自动化
我知道它是德语的，但也许有人可以帮忙。
e-plus网站的重要部分：
<tr>
<td class="td1">Benutzername:</td>
<td class="space"><img src="/img/c.gif" alt="" /></td>
<td class="td2"><input type="text" id="IDToken1OL" name="IDToken1" onfocus="setToken(this)" onblur="getToken(this)" value="Benutzername" /></td>
</tr>
<tr>
<td class="td1">Passwort:</td>
<td class="space"><img src="/img/c.gif" alt="" /></td>
<td class="td2"><input type="password" id="IDToken2OL" name="IDToken2" onfocus="setToken(this)" onblur="getToken(this)" value="" class="passwortFake" /></td>
</tr>
Powershell脚本部分：
$script:ie = New-Object -comobject InternetExplorer.Application
$ie.visible = $false
$ie.silent = $true
#
$ie.Navigate("https://www.eplus.de/login/login.asp")
LadenWarten(1)
#
$ie.Document.getElementById("IDToken1OL").value = $user
$ie.Document.getElementById("IDToken2OL").value = $passwort
$ie.Document.getElementsByTagName("a") | foreach {
if ($_.href -eq "javascript:SSO_Submit()") {
$_.Click()
}
}
getElementById适用于ie8，但现在我已经更新到ie9，它不再工作了。
错误消息：
+ $ie.Document.getElementById <<<< ("IDToken1OL").value = $user
+ CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest
参数计数错误。
我所能找到的只是一个提示，即在 ie9 中 getElementById 发生了变化。
有人可以帮忙吗？
谢谢，大卫
I use successfully a script for web automation from this site: heise web automation
I know it is in german, but perhaps someone can help.
The important part of the e-plus website:
<tr>
<td class="td1">Benutzername:</td>
<td class="space"><img src="/img/c.gif" alt="" /></td>
<td class="td2"><input type="text" id="IDToken1OL" name="IDToken1" onfocus="setToken(this)" onblur="getToken(this)" value="Benutzername" /></td>
</tr>
<tr>
<td class="td1">Passwort:</td>
<td class="space"><img src="/img/c.gif" alt="" /></td>
<td class="td2"><input type="password" id="IDToken2OL" name="IDToken2" onfocus="setToken(this)" onblur="getToken(this)" value="" class="passwortFake" /></td>
</tr>
the part of the Powershell script:
$script:ie = New-Object -comobject InternetExplorer.Application
$ie.visible = $false
$ie.silent = $true
#
$ie.Navigate("https://www.eplus.de/login/login.asp")
LadenWarten(1)
#
$ie.Document.getElementById("IDToken1OL").value = $user
$ie.Document.getElementById("IDToken2OL").value = $passwort
$ie.Document.getElementsByTagName("a") | foreach {
if ($_.href -eq "javascript:SSO_Submit()") {
$_.Click()
}
}
the getElementById worked for ie8 but now I have updated to ie9 and it is not working anymore.
the errormessage:
+ $ie.Document.getElementById <<<< ("IDToken1OL").value = $user
+ CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest
the count of the arguments is wrong.
all I was able to find was a hint, that in ie9 getElementById changed.
can anybody help?
Thanks, David

当仅自动化一个具体站点（并且脚本不是通用的或任何站点）时，您可以尝试在 IE 设置中设置兼容性视图（工具 -> 兼容性视图设置）。浏览网站时，IE 应切换到 IE8 视图。
When automating only one concrete site (and the script is not generic or any site) you can try to set compatibility view in IE settings (Tools -> Compatibility View settings). IE should switch to IE8 view when browsing the site.
使用查询选择器的示例：
