Hi experts,

I want to add a reference to a JavaScript file like the way we add dll file of .NET in D365FO. Is it possible? if yes, how can we do that?

Actually, I have written my logic, consider a method in a JavaScript file and I want to call that method in my D365FO.

I will be thankful to you.

Regards,
Arif

You can create a resource in which you can place the javascript file. For reference of this, you can check extensible controls. There javascript file will be used as a resource.

Sir Bharani Preetham,

I really appreciate your prompt response. Can you please let me know how to use that resource in my code? I am trying to access it like the below image but it's showing me an error.

Sir Bharani Preetham,

I have found how to access that resource like this.

internal final class JavaScriptTestJob { public static void main(Args _args) { ResourceNode textFileResourceNode = SysResource::getResourceNode(resourceStr(JavaScriptResource)); } }

Now, I have a method in my JavaScript file with a parameter and I have to call that from D365FO x++ and pass an argument. How can I do that?

If you want to use JavaScript through .NET Interop, you'll have to compile JavaScript to CIL. As far as I know, no such a compiler exists, therefore it's not a good idea.

There are ways how to use JavaScript from C#, but if you ask me, you shouldn't be doing such things. Either use a CLI language or implement this thing in JavaScript as a separate component.

It may be more efficient if you explain your business requirements to us, so we can help you to design a solution that is technically possible.

Sir Martin Dráb,

Suppose, I have the same requirement of integrating with a third-party website which verify an invoice which you already answered in the below link mentioned but it is in .NET dll file

https://community.dynamics.com/forums/thread/details/?threadid=c061ef80-2747-ee11-be6d-6045bdebe084

Now, I have written the same code in JavaScript file which contains a method with a parameter as object. So, now I have to access that file in D365FO directly without accessing any .NET code.

Please suggest to your best understanding.

Thanks and regards,

Arif Hussain

Hmm, so you have a solution that you can use in X++ (through .NET Interop), but you decided not to use it and rather to rewrite it in JavaScript, which you then can't use from X++. Why? It sounds like investing time to artificially create a dead end.

Sir Martin Dráb,

I have completed it in .NET and it meets my requirements and for that I am really thankful to you. And know I am trying to learn if in future I have any requirements like these doing any integration with any JavaScript or other than .NET language then how can I do that. I first thought I can do the same way like .NET but I got stuck and it's really a new thing for me to learn. I also tried creating a resource and adding my JavaScript file there but I do not know how to use that. Please suggest me with your best knowledge.

Regards,
Arif Hussain

As I said, it's sounds like a completely wrong idea to me. If you want to call JavaScript code from F&O, run it it somewhere else, such as in an Azure Function. Inside F&O, you can use either X++ or .NET Assemblies, not JavaScript.

A place where F&O uses JavaScript is on the client side, i.e. in web browsers. It means that you can use it when developing extensible controls, but not to mix it with X++ on server side.
