json on premier cep Parsing issue

[Animatinogym]

hi , 
i'm trying to parse array from js to jsx 
the pasring works Great with Aftereffects CEP
however in Premier pro it doesn't work if the data came from

JSON.stringify() it does n't work 

i simplified the code to those lines thisis .jsx 

#include 'json2.js';


function jsontest( ) {
    var randomarray = [3,5,7] ; 
    var arraystrinfied = JSON.stringify(randomarray) ;
    var myJSON = '["shark","fish","dolphin"]' ;
    var obj = JSON.parse(arraystrinfied);    // this doesn't work 
    //var obj = JSON.parse(myJSON);       this works just fine 
    alert(obj[1]); 

}

note that the same code above works fine in After effects 
what is it i'm missing ?

i tested it on a windows machine same issue 
any help would be appreciated

> the pasring works Great with Aftereffects CEP

I see that you're including Doug Crockford's json2.js, which is good, because...the JSON object available via ExtendScript is provided by the CC Libraries panel, and is only available when that panel is open. [It's unrelated to CEP.] 

Also, it seems you might need to escape at least some of the quotes in myJSON...?

Hi @Bruce Bullis  

thank you for replying 

the thing is myJASON parsed fine no issue i put it to make things clear 

the problem with the stringfied array (arrayftringfied ) 

also all works fine in aftereffects both the stringfied array and the quoted one (myJASON)

.

Is the CC Libraries panel open in PPro, when you're attempting to execute your script? If it isn't, arrayStrinfied will always be null, right?

[Animatinogym]

CC Libraries panel was closed and even when i open it the same heppens 
what drives me crazy that 

    var arraystrinfied = JSON.stringify(randomarray) ;

 is fine and i get a string data 
the stringify alone works fine

parse any Data work also fine and i get objects{} except
except the data came from JSON.stringify() this is only the issue

I have confirmed that, in PPro, when the Libraries panel is not open, none of the JSON calls above work correctly.

I have also confirmed that the code below (slightly modified from your original), DOES succeed in PPro.

var randomarray = [3,5,7] ; 
var arraystrinfied = JSON.stringify(randomarray) ;
var myJSON = '["shark","fish","dolphin"]' ;
var obj = JSON.parse(myJSON);    
alert(obj[1]);

thank you @Bruce Bullis  for making everything Clear ,
how ever 

    var randomarray = [3,5,7] ; 
    var arraystrinfied = JSON.stringify(randomarray) ;
    var obj = JSON.parse(arraystrinfied);    // this doesn't work 

this doesn't work on PPro 
sorry if Asked the wrong questions 
and thanks again .

Where, specifically, do you see it failing?

Your code works perfectly in PPro 15.2.0x35 (shipping), as long as the Libraries panel is open.

[Animatinogym]

i open the Libraries panel  just to be safe 

var obj = JSON.parse(arraystrinfied);    // this doesn't work 

 PPro 15.2.0 build 35 this is not working 
note that arraystrinfied came from JSON.stringify 
i tried another windows machine the same

Works fine here, multiple Windows machines.

Hi, this code doesn't work for me either.
This is not the first time I've come across the fact that it works for you, but it doesn't work for me

Libraries panel open

[Bruce Bullis]

That error is on line 9, which suggests that lines 6 or 7 may have succeeded.

I beg your pardon, you need to be careful what you write! Thank you! The code works

[Harchenko]

But an object that works in AE will not work in PP. This is true. For RR, the data needs to be changed
