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

[Danp2]

@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]

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

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

[Danp2]

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.

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]

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

expandcollapse popup

#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]

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]

@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]

#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]

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]

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]

@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]

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:

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]

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.
