If I want to get source a page with Javascript, Should I do?

I can't get source by _WD_GetSource()

$Source = _WD_ExecuteScript($sSession, 'document.documentElement.outerHTML')
Msg(0, 'Source', $Source)

Thank you.

Why not? Show some code we can run and post the results from the Scite output window.

NguyenLe · December 19, 2018

@Danp2 Sorry, I know the problem.

What should I do when the code is hidden inside a frame?

_WD_GetSource: {"value":"\u003Chtml xmlns=\"http://www.w3.org/1999/xhtml\">\u003Chead>\n        \u003Cmeta charset=\"utf-8\" />\n        \u003Ctitle>????????? ????? ?8389\u003C/title>\n        \u003Clink rel=\"shortcut icon\" href=\"img/ico.ico\" />\n    \u003C/head>\n    \u003Cframeset rows=\"*,70\" style=\"border: none;\" frameborder=\"no\" framespacing=\"0\" border=\"0\">\n        \u003Cframe id=\"content_frame\" name=\"content_frame\" src=\"http://www.seosprint.net/?ref=11027427\" marginwidth=\"0\" marginheight=\"0\" frameborder=\"0\" style=\"border: 0px;\" />\n        \u003Cframe id=\"counter_frame\" name=\"counter_frame\" src=\"visit_frame.php?id=8389\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" noresize=\"noresize\" frameborder=\"0\" />\n    \u003C/frameset>\u003Cnoframes>\u003C/noframes>\n\n\u003C/html>"}

Have you tried using _WD_FrameEnter to switch context to the frame and then calling _WD_GetSource?

How could i get the web driver to navigate to a page but not wait for it to load, just move onto the next line of code?

I looked into __WD_Navigate within wd_core, which lead onto WinHttp.au3 but no matter what i can comment out It always seems to wait. I cant see any obvious loops that would keep the thread from returning.

Setting _WinHttpSetTimeouts and _WD_Timeouts to 0 dont seem to help either.

I believe this was covered previously in this thread. Try searching within it for the term pageLoadStrategy.

Thanks that was perfect

For anyone else who lands on this.

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c": true, "args": ["--disable-infobars --kiosk"]},"pageLoadStrategy":"none"}}}'

is what i am now using.

I would like to use a portable version of chrome with this UDF, however I'm failing to add the parameter to the capabilities. As an Error I get missing command parameters.

Here's the code within the SetupChrome function:

Func SetupChrome()
;MsgBox(0,"",@ScriptDir & '\Chrome\chromedriver.exe')
_WD_Option('Driver', @ScriptDir & '\Chrome\chromedriver.exe')
_WD_Option('Port', 9515)
_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c":true, "binary":"' & @ScriptDir & '\Chrome\App\Chrome-bin\chrome.exe"}}}}'
EndFunc

This is the Console Output:

On the ChromeWebdriver Website i found the following option:

Quote
Using a Chrome executable in a non-standard location
ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
chromeOptions object

This is a list of all the Chrome-specific desired capabilities, which all are under the chromeOptions dictionary.

If possible, use the ChromeOptions class instead of specifying these directly.

Name Type Default Description

binary string Path to the Chrome executable to use (on Mac OS X, this should be the actual binary, not just the app. e.g., '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome')

Thanks a lot!

The issue is the backslash characters in the file path. Either replace them with forward slashes or "escape" them with another backslash.

crazycrash · December 30, 2018

Thank a ton! Also @ScriptDir needs to be changed if anyone else has the same problem! Cheers

This worked:

Func SetupChrome()
;MsgBox(0,"",@ScriptDir & '/Chrome/chromedriver.exe')
_WD_Option('Driver', @ScriptDir & '/Chrome/chromedriver.exe')
_WD_Option('Port', 9515)
_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '/chrome.log"')

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c":true, "binary":"' & StringReplace (@ScriptDir, "\", "/") & '/Chrome/App/Chrome-bin/chrome.exe"}}}}'
EndFunc

How to I get handle of the window open by Webdriver?

_WD_Window($sSession, 'handles')

or

_WD_Window($sSession, 'window')

is not that I need. I need handle for WinSetState() like 0x00020990.

Thanks!

You could use _WD_Action($sSession, 'title') to get the document title for the active tab. You should then be able to use one of the standard Autoit commands to get the window's handle by the title.

I need handle for WinSetState() like 0x00020990.

Why? There may be a better way to accomplish your goal. Please tell us which browser you are using and how you intend to use WinSetState to manipulate the window's state.

Hi friends,

I'm trying to get the element from a chrome session using _WD_GetElementFromPoint. But when the element is on an iframe , I always get a blank element id.

When I am on the session, I get the iframe element id and tag but after entering into the frame, I always get blank values.

Is there any thing else that I need to take care when I'm trying to get an element , which is in an iframe using _WD_GetElementFromPoint? Please help.

Func DemoFrames()
    _WD_Navigate($sSession, "https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_frame_cols")
    ConsoleWrite("***Number of frames=" & _WD_GetFrameCount($sSession) & @CRLF)
    While (1)
        $sElement = _WD_GetElementFromPoint($sSession, 720,290)
        $sTag = _WD_ElementAction($sSession, $sElement, 'name')
        ConsoleWrite("***Element = " & $sElement & ", Tag: " & $sTag & @CRLF)
        If StringInStr($sTag,"iframe") = 0 or $sElement = "" Then ExitLoop ;if not an iframe
        $sResult =  _WD_FrameEnter($sSession, $sElement)
        ConsoleWrite("*** Frame enter Result = " & $sResult & @CRLF)
    wend
    While not _WD_IsWindowTop($sSession)
        _WD_FrameLeave($sSession)
    Wend

    #cs

    ;ConsoleWrite("TopWindow=" & _WD_IsWindowTop($sSession) & @CRLF)
    $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//iframe[@id='iframeResult']")
    _WD_FrameEnter($sSession, $sElement)
    ConsoleWrite("TopWindow=" & _WD_IsWindowTop($sSession) & @CRLF)
    _WD_FrameLeave($sSession)
    ConsoleWrite("TopWindow=" & _WD_IsWindowTop($sSession) & @CRLF)
    #ce

EndFunc

_WD_GetElementFromPoint isn't designed to work with frames. When I have a chance, I'll see if there's a way to make it compatible with frames.

HI,

does somebody has trouble with Func _WD_NewTab?

If i start a session and my FF window the first tab is automatically opened. This is ok.

If i excute the Func _WD_NewTab(), a new Tab will be opend. This is ok.

From this on i can open as many tabs as i want. This is ok.

But if i close the first Tab, which was opend by the Func _WD_NewTab(), then Func does not work anymore.

Does somebody had the error as me?

I use the easy command

_WD_NewTab($sSession)
_WD_Navigate($sSession, 'https://duckduckgo.com/')

_WD_NewTab ==> Webdriver Exception
__WD_Post: URL=HTTP://127.0.0.1:4444/session/0ae9bf11-0fe6-4ab0-b7aa-dae67af54df9/url; $sData={"url":"https://duckduckgo.com/"}

Best regards,

horphi

Danp2 · January 11, 2019

@horphi Please post a short script that we can run to reproduce the issue you've described.

horphi · January 11, 2019

No problem...

You need to modify "_WD_Option('Driver', 'D:\YOUR_LOCAL_PATH\geckodriver-v0.23.0-win64\geckodriver.exe "--marionette-port 2828"')"

Open the session
Klick DDG Suche
Close the Tab and click again....

@horphi Thanks for the script. I'm working on a solution to the issue you found.

Danp2 · January 12, 2019

@horphi Here's a revised version of _WD_NewTab. Please review the code for any oversights on my part and then test to ensure it works as expected.

Func _WD_NewTab($sSession, $lSwitch = True, $iTimeout = -1)
    Local Const $sFuncName = "_WD_NewTab"
    Local $sTabHandle = '', $sLastTabHandle, $hWaitTimer, $iTabIndex, $aTemp

    If $iTimeout = -1 Then $iTimeout = $_WD_DefaultTimeout

    Local $aHandles = _WD_Window($sSession, 'handles')

    If @error <> $_WD_ERROR_Success Or Not IsArray($aHandles) Then
        Return SetError(__WD_Error($sFuncName, $_WD_ERROR_Exception), 0, $sTabHandle)
    EndIf

    $iTabCount = UBound($aHandles)

    ; Get handle to current last tab
    $sLastTabHandle = $aHandles[$iTabCount - 1]

    ; Get handle for current tab
    Local $sCurrentTabHandle = _WD_Window($sSession, 'window')

    If @error = $_WD_ERROR_Success Then
        ; Search for current tab handle in array of tab handles. If not found,
        ; then make the current tab handle equal to the last tab
        $iTabIndex = _ArraySearch($aHandles, $sCurrentTabHandle)

        If @error Then
            $sCurrentTabHandle = $sLastTabHandle
            $iTabIndex = $iTabCount - 1
        EndIf
    Else
        _WD_Window($sSession, 'Switch', '{"handle":"' & $sLastTabHandle & '"}')
        $sCurrentTabHandle = $sLastTabHandle
        $iTabIndex = $iTabCount - 1
    EndIf


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

    If @error <> $_WD_ERROR_Success Then
        Return SetError(__WD_Error($sFuncName, $_WD_ERROR_Exception), 0, $sTabHandle)
    EndIf

    $hWaitTimer = TimerInit()

    While 1
        $aTemp = _WD_Window($sSession, 'handles')

        If UBound($aTemp) > $iTabCount Then
            $sTabHandle = $aTemp[$iTabIndex + 1]
            ExitLoop
        EndIf

        If TimerDiff($hWaitTimer) > $iTimeout Then Return SetError(__WD_Error($sFuncName, $_WD_ERROR_Timeout), 0, $sTabHandle)

        Sleep(10)
    WEnd

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

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