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


Recommended Posts

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.

Global $BrowserPort = 4242
Global $TimeOut = 60000
Global $LocalHost = "127.0.0.1"

    Func _FFWaitWhileElement($thiselement, $elementtype = "xpath", $timeoutms = 60000)

        _FFConnect($LocalHost, $BrowserPort, $TimeOut)

        Local $Element
        Local $ElementFound = 1
        Local $TimeoutCountdown = 0
        
        While $ElementFound <> 0 And $TimeoutCountdown < $timeoutms
        
            If $elementtype = "xpath" Then
                $Element = _FFXPath($thiselement)
            EndIf
            
            If $elementtype = "id" Then
                Local $ConstructXPath = ".//*[@id='" & $thiselement & "']"
                $Element = _FFXPath($ConstructXPath)
            EndIf
            
            ; MsgBox(0, "", $Element)
            
            Local $ElementXPathTextContent = _FFCmd("FFau3.xpath.textContent")
            ; MsgBox(0, "", $ElementXPathTextContent)
            Local $ElementXPathInnerHTML = _FFCmd("FFau3.xpath.innerHTML")
            ; 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 :)

      I'm using Firefox however it shows up in all browsers.  When you hover over a hyperlink and the cursor turns to a hand then in the lower left corner of the browser the actual web URL link pops up.  How does one capture that text programmatically?  I know in FF I can right click and "Copy Link" I'm wondering if there is another way.

      I have a simple code that takes file "C:\Temp\File1.txt" and pastes it in drop area of specific firefox location ( Note : The drag drop works manually meaning firefox window supports drag and drop)  . The return value is true with no error indicating that operation successful.
      The results are not getting updated in firefox window even after exe execution completion and sleep time 20secs.
      Attached my code snippet and _FileDragDrop.au3 + text file it works 
      #include "_FileDragDrop.au3" Opt("WinTitleMatchMode", 2) ;1=start, 2=subStr, 3=exact, 4=advanced, -1 to -4=Nocase Opt("MouseCoordMode", 0) ;1=absolute, 0=relative, 2=client $File1 = "E:\AutoIt\DragDropFile\File1.txt" $File2 = "E:\AutoIt\DragDropFile\File2.txt" If ProcessExists("Firefox.exe") Then $hWnd = WinGetHandle("Mozilla Firefox") ; My FF tab title substring WinActivate($hWnd) Else MsgBox(64,"Error","No Firefox window found",10) EndIf $hNPPlus=WinGetHandle("[CLASS:Notepad++]") WinActivate($hNPPlus) $iRet = _FileDragDrop($hNPPlus, $File1, 75, 274) ConsoleWrite("Return: "&$iRet&" @error="&@error&", @extended="&@extended&@CRLF) Sleep(20000) ;~ Above code to add in Notepad++ works fine ;~ Cordinate from drop file 1 - 75, 274 $iRet = _FileDragDrop($hWnd, $File1, 75, 274,'|',False) ConsoleWrite("Return: "&$iRet&" @error="&@error&", @extended="&@extended&@CRLF) Sleep(20000) ;~ Above code to add file in firefox with title Mozilla firefox DOES NOT work Exit
       
      Repose from code -->
      Press Ctrl+Alt+Break to Restart or Ctrl+Break to Stop
      Return: True @error=0, @extended=0
      Return: True @error=0, @extended=0

      wd_capabilities.au3 UDF was changed/modified/refactored .... and commited/merged (02-12-2021) to https://github.com/Danp2/WebDriver

      WARNING: Before you start using this UDF be sure you download the recent version from: https://github.com/Danp2/WebDriver
       
      ==================================================================================================

      Recently I start wd_capabilities.au3 project on my side.
      I think this is time to share to AutoIt community.
      Check attached UDF: wd_capabilities.au3

      Here is a scratch example showing how to use them:
      #include "wd_helper.au3" #include "wd_capabilities.au3" _Example() Func _Example() ........ ........ ........ _WD_Capabilities_Build_Arguments(Null) ; CLEANUP ARGS _WD_Capabilities_Build_Arguments('--headless') _WD_Capabilities_Build_Arguments('start-maximized') _WD_Capabilities_Build_Arguments('disable-infobars') _WD_Capabilities_Build_Arguments('user-data-dir', 'C:\Users\' & @UserName & '\AppData\Local\Google\Chrome\User Data\Default') Local $s_WD_Capabilities_Arguments = _WD_Capabilities_Build_Arguments(Default) ; GET ARGS _WD_Capabilities_Build_Preferences(Null) ; CLEANUP PREFS If $s_Download_dir Then _WD_Capabilities_Build_Preferences('download.default_directory', $s_Download_dir) Local $s_WD_Capabilities_Preferences = _WD_Capabilities_Build_Preferences(Default) ; GET PREFS Local $s_Desired_Capabilities = _WD_Capabilities_Build_JSON('chrome', $s_WD_Capabilities_Arguments, $s_WD_Capabilities_Preferences) Local $WD_SESSION = _WD_CreateSession($s_Desired_Capabilities) ........ ........ ........ EndFunc  
      I plan to publish the code on GitHub.
      In the indefinite future, when the project becomes more functional, if @Danp2 accepts it, I hope it may be included in the main WebDriver UDF.

      I am waiting for yours feedback and help in the further development of this project.

      REMARK 1:
      As so far this UDF only supports GoogleChrome.
      Adding support for other browsers shouldn't be difficult, I just didn't need to.

      REMARK 2:
      For now, this project is working but still as a early BETA, so please do not discuss, ask questions, or post examples or snippets of code that pertain to any function of this UDF in other part of this forum, until it is found acceptable. Simply: discusion and tests only here in this topic.

      So I was trying to write a function that can find a button (or any other XPath Element) and scroll the page + move the mouse to the location of the button.
      My logic for this was:
      1. get position of button using _FFGetPosition
      2. get inner dimensions of browser window and total dimensions of page
      3. divide total dimensions by inner dimensions to get number of page down operations
      4. use Mod() to get remaining pixels offset
      5. MouseMove() and add requisite offsets for Titlebar etc (what the +5 and +54 is for in the last line)
      Example Code:
      _FFConnect($LocalHost, $BrowserPort, $TimeOut) Local $Button = _FFXPath(".//*[@id='thisbutton']") Local $ButtonPosition = _FFGetPosition($Button) Local $ElementWidth = $ButtonPosition[0] Local $ElementHeight = $ButtonPosition[1] Local $InnerWidth = _FFCmd("window.content.innerWidth") Local $InnerHeight = _FFCmd("window.content.innerHeight") Local $PageWidth = _FFCmd(".body.offsetWidth") Local $PageHeight = _FFCmd(".body.offsetHeight") Local $PGDNNo = Int($ElementHeight/$InnerHeight) Local $PGDNMod = Mod($ElementHeight, $InnerHeight) ; MsgBox(0,"","$ElementX: " & $ElementWidth & @CRLF & "$ElementY: " & $ElementHeight) ; MsgBox(0,"","$InnerWidth: " & $InnerWidth & @CRLF & "$InnerHeight: " & $InnerHeight) ; MsgBox(0,"","$PageWidth: " & $PageWidth & @CRLF & "$PageHeight: " & $PageHeight) ; MsgBox(0,"",$PGDNNo) ; MsgBox(0,"",$PGDNMod) Local $iter = 1 While $iter <= $PGDNNo WinActivate($BrowserWindowClass,"") _FFCmd("window.content.scrollByPages(1)") $iter += 1 WEnd MouseMove($ElementWidth + 5, $PGDNMod + 54) This isn't working. In some cases, it's not doing the page down operation the number of times needed, or not accurately pinpointing the location. I think there may be something wrong with the logic I'm using. What am I doing wrong?
      Thanks.
