Powershell, ie9 and getElementById
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>
t开发者_如何学Pythonhe 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
See http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/Q_27920160.html --
Quoted: "I should've used member invocation:
$ie = new-object -com "InternetExplorer.Application"
$ie.navigate("about:blank")
$doc = $ie.Document
$element = [System.__ComObject].InvokeMember(“getElementById”,[System.Reflection.BindingFlags]::InvokeMethod, $null, $doc, $id)
and for getElementsByTagName:
$elements = @([System.__ComObject].InvokeMember(“getElementsByTagName”,[System.Reflection.BindingFlags]::InvokeMethod, $null, $doc, $tagname))
"
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.
Example of using querySelector:
$element = [System.__ComObject].InvokeMember("querySelector",[System.Reflection.BindingFlags]::InvokeMethod, $null, $ie.Document, "$QueryHere")
