WebDriver UDF (W3C compliant version) - 2024/09/21

@thuong12382 You need to establish the location of the web driver. Please review the demo script (wd_demo.au3), which contains working examples for many of the functions.

HJL · November 9, 2018

Hello Dan,

we were using FFau3 together with MozRepl and want to change to your UDF. We did not find a function to read content from a webpage element. Is it _WD_Action or _WD_ElementAction? How does it work?

Another question: does _WD_LoadWait return the same as _WD_FindElement? If not, that would save code.

Have a nice weekend

Hans

Danp2 · November 9, 2018

Hi Hans,

You would use _WD_ElementAction to interact with an element. To retrieve its value, use 'text' as the value for the $sCommand parameter.

This has been previously suggested for _WD_WaitElement. Is that what you mean? If not, please elaborate.

Here is my radio buttons example:

My example radio buttons

Here is my simple code:

#include <wd_core.au3>
#include <wd_helper.au3>

Local $sDesiredCapabilities, $sSession

Func SetupChrome()
    _WD_Option('Driver', 'chromedriver.exe')
    _WD_Option('Port', 9515)
    _WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

    $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"chromeOptions": {"w3c": true, "args":[' & """start-maximized""," & " ""disable-infobars""" & "" & '] }}}}'
 EndFunc   ;==>SetupChrome

SetupChrome()
_WD_Startup()

$sSession = _WD_CreateSession($sDesiredCapabilities)
_WD_Navigate($sSession, "https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_custom_radio")

$radio_4 = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//span[@class='checkmark']")
_WD_ElementAction($sSession, $radio_4, 'click')

_WD_Shutdown()

Can you help me to choose the radio button "Four". I have tried several times. I am new to this UDF, html and css. Thank you <3

That site uses iframes, so you'll need to switch to the correct frame before you can locate the element with WD_FindElement. This can be done with _WD_Window or the helper function _WD_FrameEnter.

Check out the DemoFrames function in wd_demo.au3 for an example of using these functions.

Local $aDemoSuite[][2] = [["DemoTimeouts", False], ["DemoNavigation", False], ["DemoElements", False], ["DemoScript", False], ["DemoCookies", False], ["DemoAlerts", False],["DemoFrames", False], ["DemoActions", True]]

_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

EndFunc

I have tried that example but i still don't know how to click that radio or reach to its ID . I am noob, can you tell clearlier?

Danp2 · November 11, 2018

That site is odd because it's using a custom radio button, but here's two ways to select the radio buttons --

#include "wd_core.au3"
#include "wd_helper.au3"

Local $sDesiredCapabilities
Local $iIndex
Local $sSession

$_WD_DEBUG = $_WD_DEBUG_Info

SetupChrome()

_WD_Startup()

$sSession = _WD_CreateSession($sDesiredCapabilities)

_WD_Navigate($sSession, "https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_custom_radio")
ConsoleWrite("Frames=" & _WD_GetFrameCount($sSession) & @CRLF)
$sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//iframe[@id='iframeResult']")
_WD_FrameEnter($sSession, $sElement)

; Method 1
$sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//label[3]/input")
_WD_ElementAction($sSession, $sElement, 'click')

Sleep(3000)

; Method 2
$aElements = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//input", "", True)
;_ArrayDisplay($aElements)
_WD_ElementAction($sSession, $aElements[0], 'click')

Sleep(3000)

_WD_FrameLeave($sSession)
_WD_DeleteSession($sSession)
_WD_Shutdown()

Func SetupChrome()
    _WD_Option('Driver', 'chromedriver.exe')
    _WD_Option('Port', 9515)
    _WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

    $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"chromeOptions": {"w3c": true }}}}'
EndFunc   ;==>SetupChrome

_WD_WaitElement is what I was looking for - perfect. Thanks for your help and for this UDF....

pempemHY · November 20, 2018

Hi Dan, when i choose the $Command is 'action' in the function _WD_Action, can i control the page to scroll down? And how to do it?

Danp2 · November 20, 2018

@pempemHY Please provide a better description of what you are attempting to accomplish. Show us what you've tried thus far.

P.S. There may be a better way than using "actions".

pempemHY · November 20, 2018

#include "wd_core.au3"
#include "wd_helper.au3"

Local $sDesiredCapabilities
Local $iIndex
Local $sSession

$_WD_DEBUG = $_WD_DEBUG_Info

SetupChrome()
_WD_Startup()
$sSession = _WD_CreateSession($sDesiredCapabilities)
_WD_Navigate($sSession, "https://www.youtube.com/")
Sleep(500)
_WD_Action($sSession, "actions", 'PageDown')
;ControlSend($handles, "", $controlID, '{PGDN}')
Sleep(20000)
_WD_DeleteSession($sSession)
_WD_Shutdown()

Func SetupChrome()
_WD_Option('Driver', 'chromedriver.exe')
_WD_Option('Port', 9515)
_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"chromeOptions": {"w3c": true }}}}'
EndFunc

i try this with Youtube, key wasn't sent. Should i use ControlSend? Can i get controlID and handle of my session with this UDF?

Danp2 · November 20, 2018

In many cases, the scrolling will occur automatically once you interact with an element.

Why do you want to scroll the view? Again, what's your end goal?

pempemHY · November 20, 2018

Thank you, my problem was solved. Some elements at the bottom of the page (must use PageDown if you wan to see them) can't be interacted,.To solve this, i have set fullscreen chrome and it's OK.

Danp2 · November 20, 2018

@pempemHY I'd like to better understand the issue. Can you post an example, ideally with a publicly accessible website, where you can't interact with the element unless the browser is full screen?

Acanis · November 20, 2018

Hey Danp2, thanks for creating this UDF

Didnt code some time, so maybe Iam just confused, but I cant get it to run^^...

I downloaded the UDFs JSON, WinHttp and this one.
I unpacked the chromedriver in the same folder with wd_demo.
I started the demo with SciTE and changed: Local Const $_TestType = $eChrome
I start the demo (1 Chrome window is already open), and nothing happens with Chrome. All I can see, is that the driver is opening.

Iam using the newest Chrome version, every UDF and the driver are fresh downloaded, my AutoIt version is: 3.3.14.2

The demo is closing after a few seconds, my console says:

_WDStartup: OS: WIN_10 WIN32_NT 17134 
_WDStartup: AutoIt: 3.3.14.2
_WDStartup: WD.au3: 0.1.0.15

Do you know, what Iam doing wrong?

Thanks

@Acanis

It appears that they changed something in the latest version of ChromeDriver. I'll post back if I get it working.

Dan

P.S. You could also try downgrading to the prior version of ChromeDriver.

Edited November 20, 2018 by Danp2

Danp2 · November 20, 2018

Ok... it looks like "chromeOptions" has been changed to "goog:chromeOptions".

I'll change this in wd_demo and will be releasing an update to the UDF soon.

Try this code! Then delete the line "_WD_Window($sSession, 'fullscreen')" and try it again . See the difference.

@pempemHY I tried running your code, but it seemed to get hung up in this area --

$button_go = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//a[@id='u_0_1w']")
_WD_ElementAction($sSession, $button_go, 'click')

Not sure what this should be doing. Would really help if you could provide a much simpler example to review.
