FF.au3: _FFWaitWhileElement() --- A Function to pause script until Element CANNOT be found on page

[noellarkin]

This is for those pages that seem to load when you use _FFOpenURL(), but they have a text saying "please wait while we load your page..." but according to _FFOpenURL() the page has loaded.  An example seen in popular sites is the Cloudflare page saying "Checking your browser before...". It's the opposite of pausing a script until an element is visible on a page. It takes Elements in the form of id, xpath or text search.

                Local $ConstructXPath = ".//*[@id='" & $thiselement & "']"

            ; MsgBox(0, "", $ElementXPathInnerHTML)
            If $ElementXPathTextContent = "_FFCmd_Err" Or $ElementXPathInnerHTML = "_FFCmd_Err" Then
                $ElementFound = 0
                Else
                $ElementFound = 1
            EndIf
        
            If $elementtype = "text" Then
                $ElementFound = _FFSearch($thiselement)
                ; MsgBox(0, "", $ElementFound)
            EndIf

            $TimeoutCountdown += 1000
            _FFDisConnect()
            _FFConnect($LocalHost, $BrowserPort, $TimeOut)
        WEnd
        Return $ElementFound

    EndFunc

_FFConnect($LocalHost, $BrowserPort, $TimeOut)
_FFOpenURL("https://www.site.com/page", True)
_FFWaitForElement("Please Wait...","text", 60000)
MsgBox(0,"","Page finished loading")

It's pretty simple, hope it helps some of you who are working with FF.au3 :)
