Is there any way of instantiating the "chakra.dll" in the form of an object?
something similar to as described here (but for C#), where this command 'host = new ChakraHost();" is used to instantiate Chakra as an object, and then the dot notation syntax is used to call the methods 'host.CallFunction("commitFunction");'  ......?

I think that would require wrapping the functions in some kind of COM object (AutoItObject for example), since ChakraCore.dll exposes only "flat API", i.e. exported DLL functions. ("Note that JSRT APIs are C++ APIs, this sample assumes a C# wrapper.", as it says on the Embedding ChakraCore page).

Hi @scintilla4evr, thanks for your answer

I was wondering if what says @guinness  in his topic here, could be used with this chakradll as well..?

anyway, back on your udf, could you show how to use it if, for example, I would like to use the functions from this 'moment' javascript library directly from AutoIt? (library found on this nice site)

any example is welcome

Thank You :)

Help a poor newbie !

Congratulations, but

I can't find out what's wrong with chakracore.au3  when calling a quite basic execution on the example 1 mode :

(function() {
    var h = window.document.location.href ;
    return h ;
})();

Many thanks in advance.

Func _ChakraCore_Startup($sDllFile = "Chakra.dll")

I had to remove the core part from the dll name and then it works. Powefull extension

My output from the examples

  1. JavaScript Output: 5
  2. JavaScript Output: 13
  3. JavaScript Output: llo Wor
  4. JavaScript Output: Lorem ipsum dolor sit amet
  5. a: 320

Sorry for such a GIGANTIC delay in answering this question.

You can't use window.document.<blah blah insert some object here> in ChakraCore, because the window object is exposed only by web browsers. This UDF only gives access to "raw" JavaScript, so there are no browser-specific objects - no window, navigator, DOM, etc.

      The DOM allows to do anything with elements and their contents, but first we need to reach the corresponding DOM object, get it into a variable, and then we are able to modify it. *
      Well, this little tool (although it is not very nice aesthetically) allows you to get visually a "selector" usable to reference DOM objects.
      Once you have the "selector" of an element you can pass it to the javascript querySelector() function that will return a reference to that element.
      To use this tool you have to:
      1) open the web page you want to inspect into IE browser
      2) run this script (if it find more instances of IE running, it allows you to chose one)
      3) move the mouse over the browser. The "selector" of the element below the pointer is catched automatically while hovering. To copy the selector in the clipboard just right click on the element.
      As you can see, while hovering, the element pointed by the mouse is highlighted with a thin red dotted frame to allow you to better "take aim"
      when the selector is copied to the clipboard a little acoustic signal is emitted as a confirm, then you can paste it in your listing where you need it.
      I hope it can come in handy and save you time when you need to automate a site .... have fun (debugged on Sept. 30 2018)

      suppose we want automate the login to the AutoIt site with our username and password.
      I've already prepared a very simple "template" where are missing some important parts without which the script can't work. Missing parts are the references to the elements of the AutoIt web page that we have to manage by our script.
      well, here is where the tool I have just posted here above comes to our help.
      follow this steps:
      1) in IE open the AutoIt site at the forum page (https://www.autoitscript.com/forum/)
      2) run the above tool (select the IE instance and/or bring it to front if needed)
      3) when the script is "ready", move the mouse over the "Existing user? Sign In" string and right click the mouse button. Doing so the "selector" of that element is copied to the clipboard. Now we can paste it in our AutoLogIt.au3 script as value of the $sSignIn variable.
      4) now click on the "Existing user? Sign In"  to open the "Sig In" session from where we will copy selectors of each of the 2 input box Username and Password, in the same way as we have already done in step 3, and paste those selectors to the $sInputUserId and $sInputPasswd variables respectively.
      5) do the same for the "Sign In" Button and paste it's selector to the $sSignInButn variable
      6) of course also fill the $sMyUserId and $sMyPasswd variables with your data.
      That's It. Run the AutoLogIt script and it should Log you on automatically to the forum.
      AutoLogIt.au3
      #include <ie.au3> $sMyUserId = "" ; <-- your userid here $sMyPasswd = "" ; <-- your password here ; set selectors here $sSignIn = "" ; <-- SigIn element selector here $sInputUserId = "" ; <-- UserId input selector here $sInputPasswd = "" ; <-- Password input selector here $sSignInButn = "" ; <-- Sig In button selector here $oIE = _IECreate("https://www.autoitscript.com/forum/") ; here is how to use the QuerySelector javascript function $hDOM_Element = $oIE.document.QuerySelector($sSignIn) ; get the "sign in" link element ; perform a click action on the above element $hDOM_Element.click() ; or _IEAction($hDOM_Element, "click") as well ; fill the username input $hDOM_Element = $oIE.document.QuerySelector($sInputUserId) $hDOM_Element.value = $sMyUserId ; fill the password input $hDOM_Element = $oIE.document.QuerySelector($sInputPasswd) $hDOM_Element.value = $sMyPasswd ; .... or also using the dot notation directly .... $oIE.document.QuerySelector($sSignInButn).click() Sleep(5000) ; this should logout $sMenu = "body > div:nth-of-type(2) > header > div > ul > li:nth-of-type(6) > a:nth-of-type(2)" $oIE.document.QuerySelector($sMenu).click() $sLogOut = "body > ul > li:nth-of-type(9) > a" $oIE.document.QuerySelector($sLogOut).click()

      This is a little experiment that makes use of a "Browser Control" embedded in a GUI in order to be able to use AutoIt, HTML, JavaScript and CSS all together.
      This little toy will only work on systems with IE11.
      The purpose is to drag all the names of the scientists & drop on the right ones. (among scientists it has also infiltrated an intruder). I hope you find it entertaining.
      I've posted it here in the hope to have some suggestions on how to improve it all (I mean the interaction between Autoit Javascript html and css). Thanks

      Here the this wiki page with list of available UDFs for data compression. For my tasks I only need ZIP support, so I started looking at pure AutoIt UDFs without any 3rd party dlls. And found out that most of available realizations uses standard ("native method") Windows dll - "zipfldr.dll". So for now I chose ZIP UDF by wraithdu. I've tested it on Windows 7 (x64) and it seem works fine. But here the comment from another topic where user says that Windows 10 discontinued support of "zipfldr.dll". Now I confused. I don't have around any Windows 10 machine to tested it. So maybe someone could confirm or deny that? Or maybe would better to switch to UDF with 7zip dll?
      I need an advice...

      Here is the bare bones of a UDF I have started work on.
      Mostly just a proof of concept at this stage, and still need to add some functions and dress the UDF up a bit ... to look like a UDF ... though it has my own distinct styling, especially as I have never really developed a UDF before now .... used plenty and modified plenty though. I've even invented my own UDF variable naming convention, which I am sure some of you will be aghast at. I work with what feels best for me, but others are free to adapt if they wish.
      The idea is to emulate the simplicity of INI files, but gain the benefits of SQL.
      Two scripts are provided.
      (1) The UDF, a work in progress - SimpleSQL_UDF.au3
      (2) An example or testing script - UDF_Test.au3
      Another first for me, is creating a 2D array from scratch, never done that before, that I can recall ... never had a need, and even for 1 dimension arrays, for a long time now, I have just used _StringSplit to create them. So I needed a bit of a refresher course, which my good buddy @TheDcoder assisted me with ... not without some angst I might add. LOL
      SimpleSQL_UDF.zip  (12 downloads previously)
      (I have now completed all the functions I intended to. My next update will be a big improvement, bringing things more inline with my latest INItoSQL DB program changes.)
      Program requires the sqlite3.dll, not included, but easily enough obtained.
      Hopefully the usage is self-evident ... just change the Job number variable in the UDF_Test.au3 file to check the existing functions out.
      Enjoy!
      P.S. This is also related to a new program I have just finished and uploaded - INItoSQL DB
