Hello @GregEisenberg You need to do this: Local $oJsonRect=_WD_ElementAction($sSession, $sElements, 'rect') ConsoleWrite("!" & Json_Get($oJsonRect, "[x]") & @CRLF) ConsoleWr

@NguyenLe, this is a continuation of our discussion from the other thread.

 

If you examine the code for _WD_WaitElement, you will see that it just calls _WD_FindElement in a loop. Can you provide a simple example where _WD_FindElement doesn't find an element that is present on the page? Be sure to utilize a website that is accessible to everyone.

Also, it would be interesting to get your perspective on whether this issue could be related to the character encoding.

@mrPuh What about the Opera webdriver console? Can you post the output from there?

P.S. Add some error checking to your code. For example -- 

$sSession = _WD_CreateSession($sDesiredCapabilities)

If @error = $_WD_ERROR_Success Then
    _WD_Navigate($sSession, "https://www.earnstations.com/")
    _WD_WaitElement($sSession,$_WD_LOCATOR_ByXPath,"//a[@class='btn']")
    $sElement = _WD_FindElement($sSession,$_WD_LOCATOR_ByXPath,"//a[@class='btn']")
    _WD_ElementAction($sSession, $sElement, 'click')
EndIf

When I launch Chrome webdriver in console this message.

When I launch Opera webdriver in console this message and Opera don't launch.

When I set $sDesiredCapabilities = '{"capabilities": { } }' in AutoIT console this:

It looks like you will need to keep trying different options until you find a working example.

You may want to review the following links f you haven't already done so --

I've downloaded all the necessary files to the necessary directories (I think)

I'm trying to get this to work and think I've got part way there (firefox isn't my default browser)

I'm a little confused about using  _WD_ or _WD  as for example in _WD_Navigate or _WDNavigate  this one seems to work _WDNavigate

I see in wd_core.au3  there is a parameter Global $_WD_DRIVER = "" ; Path to web driver executable 

  

#include "wd_helper.au3"
#include "wd_core.au3"
Global $_WD_DRIVER
Local $sDesiredCapabilities
Local $iIndex
$sCommand ="C:\Program Files (x86)\Mozilla Firefox\"
$_WD_DRIVER = $sCommand & "firefox.exe"

SetupGecko()
_WDStartup()
$sSession = _WDCreateSession($sDesiredCapabilities)
_WDNavigate($sSession, 'http://google.com')
$sElement = _WDFindElement($sSession,$_WD_LOCATOR_ByXPath,"//a[@class='gsfi']")

If @error = $_WD_ERROR_Success Then
    _WDElementAction($sSession, $sElement, 'value','Hello')
EndIf

Func SetupGecko()
_WDOption('Driver', 'C:\Users\PC1\Documents\AutoIt_code\geckodriver.exe')
_WDOption('DriverParams', '--log trace')
_WDOption('Port', 4444)

$sDesiredCapabilities = '{"desiredCapabilities":{"javascriptEnabled":true,"nativeEvents":true,"acceptInsecureCerts":true}}'
EndFunc

I'm a little confused about using  _WD_ or _WD  as for example in _WD_Navigate or _WDNavigate  this one seems to work _WDNavigate

The Console gives me:

_WDStartup: OS: WIN_10 WIN32_NT 16299
_WDStartup: AutoIt: 3.3.14.3
_WDStartup: WD.au3: 0.1.0.3

Thanks I'd hoped this would do the trick (but didn't):

  

Func SetupGecko()
$ff = '--binary C:\Program Files (x86)\Mozilla Firefox\firefox.exe'
_WDOption('Driver', 'geckodriver')
_WDOption('DriverParams', $ff)
_WDOption('Port', 2828)

$sDesiredCapabilities = '{"desiredCapabilities":{"javascriptEnabled":true,"nativeEvents":true,"acceptInsecureCerts":true}}'
EndFunc

The DriverParams is used to pass parameters to the web driver. It's not for indicating the location of the browser executable. This would be done as part of DesiredCapabilities, which gets passed to _WD_CreateSession.

Edit: @Jury I just reread the flags section and see where they say this should work as you indicated. Can you post the contents from the Scite output window?

Thanks a lot, @Danp2. Your UDF works great. Now I have 2 questions. First, what is the syntax of $sDesiredCapbilities? For example, how do I integrate 'start-maximized' option in the $sDesiredCapabilities? The 2nd question is, what happens if I don't call _WD_DeleteSession() function at the end of my code? Will it create any prolem if I do it repeatedly, such as temporary files piling up in the computer? Currently I'm not calling this function because I want to keep the website open after the code is finished. I just call _WD_Shutdown(). Your answers will be greatly appreciated.
