store objects in associative array

Question

How do I store ExtendScript objects in associative array?

var assArray = {};

for (i=1; i<=app.project.items.length; i++) {
    //alert(app.project.item(i).name); one of them is "_vegs"
    assArray[app.project.item(i).name] = app.project.item(i);
}

alert(assArray["_vegs"].name);

This code returns error at the second alert line.

Unable to execute script at line 9. undefined is not an object.

What am I missing here?

Why do you count from 1 to `length`, why not from 0 to `length-1` ? — fafl, Jan 27 '17 at 12:29
Checkout "push". var myarray = [] and then myarray.push(...), see https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Array/push and sorry for micro editing :-) — Gunnar, Jan 27 '17 at 12:34
@Gunnar I need to access items by its name later on. I don't want to use normal array. — sanjihan, Jan 27 '17 at 12:35
@sanjihan, I created a dummy project with item named `_vegs` and ran your code and it works fine. Probably you have different error. Try running your code on dummy project. — Ziki, Jan 29 '17 at 13:39
@sanjihan I can not confirm your error. It works for me as well. Didn't have `_vegs` in it but other names with whitespaces. The error must come from something else. — fabianmoronzirfas, Feb 02 '17 at 06:47

var assArray = {};

for (i=1; i<=app.project.items.length; i++) {
    //alert(app.project.item(i).name); one of them is "_vegs"
    assArray[app.project.item[i].name] = app.project.item[i];
}

alert(assArray["_vegs"].name);

I think the problem is in (i) hopefully [i] will work

Nah, item() is a function in extendscript. It looks like they don't allow storing objects in arrays. – sanjihan Jan 27 '17 at 13:49
