How do I call ExtendScript functions from Javascript

[Jiajun22852525kmyb]

Hello!

I am struggling to connect JS and Extendscript. To start, my folder path is workspace/client/index.js and workspace/host/index.jsx.

My JS code is:

and my JSX code is:

I want to return the path, start, and end times from Extendscript, but I'm not getting any return value from JS. What am I doing wrong? Thank you!

"I'm not getting any return value from JS" - I meant JSX

Also, I just realized that I'm missing a bracket, but after fixing that it still did not print the return value. I added a simple console.log("hi"); before the evalScript and that printed out though.

Update: I removed the brackets from getInfo() in  ' csInterface.evalScript("getInfo()", function(array_string) ' and it printed the whole entire function as a string. Not what I intended, but at least that's something. What went awry?

I just realized that getInfo returns a string of the function which is why it works. 

my jsx looks like this now:

and my js looks like this:

However, I'm getting an EvalScript Error and I don't know why.

Can somebody help? Thank you!

PProPanel offers multiple examples of getting data across the ExtendScript <--> JavaScript boundary. 


Also, when calling evalScript() within JavaScript, you'll need to include the outermost layer of ExtendScript defintion, so you'd reference '$._FUNCTIONS.getInfo', not 'getInfo'.

Hello Bruce! 

I tried referencing the function as you stated, but I am not printing anything out to the debug console except for the "hello" before I call evalScript().

This is my js code right now:

This is my jsx code:

Ideally, getInfo() should return "hi" and then be printed out to the console, but at the moment it's not working. If I change .getInfo() to .printHi() though, it does print "hi" which is very puzzling. Thank you!

I checked the post and they cited another post that helped them solve the issue. However, the one that they cited doesn't exist anymore, and they solved their problem by removing a manifest reference to an empty jsx file, which for me isn't empty. I tried to debug the code again and then I found out that the getInfo works when I just have a return "hi" statement, but fails to return anything when I copy my extendscript code into the function. I checked my extendscript code separately using the debugger before and it works, so is there anything else that would cause the return to fail? Thank you!

That makes no sense.

Send me the actual extension, please.
