Use HTML form as GUI for powershell

Question

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

Answer 1

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

$html = @"

    
        

                First name: 
            

                Last name: 
            

            
            
    

"@

$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()
