I have a powershell script that I would like to run using an html form. All I have is a few form fields and a button. When I run my powershell script, it opens a new ie window

    I add javascript by using the execScript("SCRIPT HERE","Type Of Script") of the parent window

    $html = @"
<html>
    <body>
        <form>
                First name: <input type="text" id="firstname">
            <br>
                Last name: <input type="text" id="lastname">
            <br>
            <input type="button" id="finished" value="Submit" onclick=''>
            </form>
    </body>
</html>
"@

$ie = new-object -com "InternetExplorer.Application"
$ie.navigate("about:blank")
$ie.document.body.innerHTML = $html
$doc = $ie.Document
$doc.parentWindow.execScript("document.getElementById('finished').onclick = function(){document.getElementById('finished').value = 'Submitted';};","javascript")
$ie.Visible = $true

while ($doc.getElementByID("finished").value -ne "Submitted") {
    start-sleep -m 500
    $firstName = $doc.getElementByID("firstname").value
    $lastName = $doc.getElementByID("lastname").value
}

$ie.Visible = $false
"You answered:"
$doc.getElementByID("firstname").value
$doc.getElementByID("lastname").value
$ie.quit()

    I was trying to accomplish the same thing and ran across your post. I see it's been about 8 months, but if you're still looking here's what I found. I was not able to get "onclick" to work. So I used a hidden input field, and defined an action for the button to update the value of that field. In powershell I getElementbyId for the hidden field, and use that to recognize the user has completed the input.

    $html = @"
<html>
<body>
<form>
First name: <input type="text" id="firstname">
<br>
Last name: <input type="text" id="lastname">
<br>
<input type="hidden" name="finished" value="0">
<input type="button" id="button" value="Continue" onclick="finished.value=1">
</form>
</body>
</html>
"@

$ie = new-object -com "InternetExplorer.Application"
$ie.navigate2("about:blank")
$ie.AddressBar  = $false
$ie.MenuBar     = $false
$ie.StatusBar   = $false

$ie.document.body.innerHTML = $html
$ie.Visible = $true
$doc = $ie.document

while ($doc.getElementByID("finished").value -ne 1) {
    start-sleep -m 500
}

$ie.Visible = $false
"You answered:"
$doc.getElementByID("firstname").value
$doc.getElementByID("lastname").value
$ie.quit()

    I've been wondering if this actually works well:

    http://social.technet.microsoft.com/wiki/contents/articles/how-to-add-a-graphical-user-interface-to-a-powershell-script-by-using-html-applications.aspx

    It's based around running a PowerShell process from VBScript and then using the clipboard to transfer the output back to the HTA.

    Sounds like a half decent hack, I've not tried it for myself yet though.

    @Clayton It works fine for on other windows 10 OS System but gives an error on Windows 10 Azure VM

    Error- The property 'innerHTML' cannot be found on this object. Verify that the property exists and can be set. At line:24 char:1

    Because you are already able to open a new ie window from your powershell script and navigate to the correct page, I'm assuming that you are using InternetExplorer Object. That's why I'm thinking @ravikanth link is good for you. From there (and from many other posts on the internet) you can see how to grab value fields using $ie.Document.getElementById("fieldid").value, do you?

    Another option is System.Net.WebClient which is the proper way to GET/POST web page data. You have a nice example here.

    Otherwise, I think you should be more clear about what you want to do and provide some code sample of what you are trying to do.
