Why does javascript "Object.keys()' not work with Autohotkey? Topic is solved

[gues747747474]

Code: Select all

JS_Products_Oject = 
(join`r`n
{
"grogu":{"price":50,"Iva":10},

"strela":{"price":100,"Iva":15},

"zzz":"End"}
)

js_code = 
(join`r`n

Products = %JS_Products_Oject%;

Products_Keys = Object.keys(Products).join("|");

)

	;ComObjError(false)		;turn error message box off

SC := ComObjCreate("ScriptControl")
SC.Language := "JScript"

	;SC.alert("hh")		;"alert()" does not work

SC.Eval(js_code)

MsgBox, % ""
. SC.Eval(Products_Keys)               "`r`n`r`n"

If you load a JavaScript engine of the appropriate version, it will work.

ScriptControl is very old.

There are at least a few ways to load a newer engine:

• Create an InternetExplorer.Application with ComObjCreate and write a document/script into it.
• Create a htmlfile with ComObjCreate and write a document/script into it.
• Create a GUI with an ActiveX WebBrowser control... and write a document/script into it.
• Use JsRT.ahk and ActiveScript.ahk. Usage is shown on GitHub (use either JsRT.IE11 or JsRT.Edge).
• Use JsRT or ChakraCore via DllCall (ChakraCore is open source and probably more up to date).

I tried JsRT.ahk/ActiveScript.ahk on my win10 system and still got no dice:

Code: Select all

js := new JsRT.Edge()

code =
(
var Products = {"grogu":{"price":50,"Iva":10},
"strela":{"price":100,"Iva":15},
"zzz":"End"}

var Product_keys = Object.keys(Products)
var stringVals = [1,2,3].join("|");
)
js.Exec(code)
js.Product_keys
; => {}
js.stringVals
; => "1|2|3"

Its like Object doesn't exist.

However if javascript is not crucial to this flow; https://biga-ahk.github.io/biga.ahk/#/?id=keys may be able to produce the same data:

Code: Select all

A := new biga() ; requires https://www.npmjs.com/package/biga.ahk

products := {"grogu": {"price": 50, "Iva": 10}
, "strela": {"price":100, "Iva":15}
, "zzz": "End"}

A.keys(products)
; => ["grogu", "strela", "zzz"]

I only went as far as

Code: Select all

#Include <ActiveScript>
#Include <JsRT>

script := new JsRT.IE  ; IE11 feature set.
; script := new JsRT.Edge  ; Edge feature set.

MsgBox % script.eval("typeof Object.keys")

Which shows "function" in either case.

Code: Select all

#Include <ActiveScript>
#Include <JsRT>

script := new JsRT.IE  ; IE11 feature set.
; script := new JsRT.Edge  ; Edge feature set.

MsgBox % script.eval("JSON.stringify(Object.keys({a:1,b:2}))")

Shows ["a","b"].

Object is defined even with the version of JScript used by ScriptControl.

js.Product_keys
; => {}

How did you determine that? Product_keys contains a JScript Array of three items, not a string. Why are you using join() in one case and not the other?
