Try this:


_WD_ExecuteScript($sSession, 'document.getElementsByTagName('p')[1].select();')

I tried this already...works unfortunately not...:-(

 

_WD_ExecuteScript: {"value":{"error":"javascript error","message":"TypeError: document.getElementsByTagName(...)[1].select 
 --> is not a function","stacktrace":"execute_script @, line 0\ninline javascript, line 1\nsrc: \"undefined\"\nStack:\n

Maybe some minor hint to _WD_NewTab

A error occurs if no browser is opend and the script interrupt.

Func _WD_NewTab($sSession, $lSwitch = True)
    Local Const $sFuncName = "_WD_NewTab"
    Local $sTabHandle = ''

    _WD_ExecuteScript($sSession, 'window.open()', '{}')

    If @error = $_WD_ERROR_Success Then
        Local $aHandles = _WD_Window($sSession, 'handles', '')
        
        $sTabHandle = $aHandles[UBound($aHandles) - 1] ;<<<<<<<<<<<<<<<<<<<<<<If this is no array, script interrupt

        If $lSwitch Then
            _WD_Window($sSession, 'Switch', '{"handle":"' & $sTabHandle & '"}')
        EndIf
    EndIf

    Return SetError($_WD_ERROR_Success, 0, $sTabHandle)
EndFunc


Func _WD_NewTab($sSession, $lSwitch = True)
    Local Const $sFuncName = "_WD_NewTab"
    Local $sTabHandle = ''

    _WD_ExecuteScript($sSession, 'window.open()', '{}')

    If @error = $_WD_ERROR_Success Then
        Local $aHandles = _WD_Window($sSession, 'handles', '')
          If IsArray($aHandles) Then
        $sTabHandle = $aHandles[UBound($aHandles) - 1]
          Else
            ConsoleWrite("> An error occurred. " & 'No Session exist.' & @CRLF)
        EndIf

        If $lSwitch Then
            _WD_Window($sSession, 'Switch', '{"handle":"' & $sTabHandle & '"}')
        EndIf
    EndIf

    Return SetError($_WD_ERROR_Success, 0, $sTabHandle)
EndFunc

@horphi Probably need to check the value of @error after the call to _WD_Window. I'll have to do some testing, but would have thought that the earlier call to _WD_ExecuteScript would have failed.

Edit: Fixed _WD_ExecuteScript so that it properly sets @error

Hello. Tested with  Microsoft WebDriver (version 16299).

 

Here the Setup Function

Func SetupEdge()
_WD_Option('Driver', 'MicrosoftWebDriver-16299.exe')
_WD_Option('Port', 17556)
EndFunc

_WD_CreateSession need to be modified becuase the sessionid is not returned here [value][sessionId] It's retuned here [sessionId] That's all

I tested just few commands navigate,FindElement,Action But I think all will work correctly.

 

Saludos

the handle do not return from the new tab, because this tab does not have time to create

Fixed _WD_NewTab

Func _WD_NewTab($sSession, $lSwitch = True)
    Local Const $sFuncName = "_WD_NewTab"
    Local $sTabHandle = ''
    Local $TimerNewTab = 0
    _WD_ExecuteScript($sSession, 'window.open()', '{}')
    $TimerNewTab = TimerInit()

    While 1
        If TimerDiff($TimerNewTab) > 5000 Then Return SetError($_WD_ERROR_Success, 0, $sTabHandle)
        If @error = $_WD_ERROR_Success Then
            Local $aHandles = _WD_Window($sSession, 'handles', '')
            $sTabHandle = $aHandles[UBound($aHandles) - 1]
            If $lSwitch Then
                _WD_Window($sSession, 'Switch', '{"handle":"' & $sTabHandle & '"}')
            EndIf
            ExitLoop
        EndIf
        Sleep(10)
    WEnd
    Return SetError($_WD_ERROR_Success, 0, $sTabHandle)
EndFunc   ;==>_WD_NewTab

Now, if the tab is not created within 5 seconds, it returns an SetError

Thanks for the feedback. Can you provide further details so that I can replicate the issue? Which browser, etc.

Also, I can see a few issues with this revised implementation, such as --

  • Possible misplaced If @error check.
  • Wrong return value when timeout occurs
  • How do you determine that the new tab exists?

Finally, I would suggest making the timer "max" value an optional parameter.

P.S. Perhaps an even simpler implementation would be to replace the timer loop with a single Sleep command using the same optional variable to allow the calling routine to determine the desired delay length.

Yes, you're right, I have not yet found how to fix this inside this function. Perhaps, if the _WD_ExecuteScript will store errors in the global variable, and I will check it through

While 1

if $GlobalVariableOfErrorExecuteScript='okay'  then exitloop

wend

Yes, this is a simple implementation. But, for example, if you have a heavily loaded virtual machine and the fiefox tab will be created for a very long time, it will not always work sleep. Of course SLEEP can be done for 5 minutes :) but in some tasks some people can lose a lot of money.

Does it fail for you every time in this environment? If so, please change $_WD_DEBUG = True and post the contents of the Scite output window after running your code.

Also, is there a reason you aren't running the latest version of Autoit?

If $HandleTab<>'' then MsgBox(0,"","Table IS EXIST, because it return value of handle")
 _WD_Window($sSession, 'Switch', '{"handle":"' & $HandleTab & '"}')
EndIf

But the current implementation should return the handle of the last tab (even if the newest one hasn't appeared as you previously indicated). So $HandleTab would only be blank if there was an error from _WD_ExecuteScript.

Why Wrong? 

if i change timeout 5000 to 0

If TimerDiff($TimerNewTab) > 0 Then Return SetError($_WD_ERROR_Success, 0, $sTabHandle)

i return $HandleTab='' (nothing)

Actually, I meant the error code, not the return value. I would use $_WD_ERROR_Timeout here instead of $_WD_ERROR_Success

Shouldn't be necessary to use a global here. Look at other instance where the value of @error is saved to $iErr.
