I get this in the Console

Interface: BD
Interface: Ludwig
Interface: SD
Interface: Tamba
Interface: HH
Interface: chris

What are you expecting to see?

@d-healey said in Print Object Value for Object Key; not working:

u expecting to see

Yes same here.
Im expecting to get:
BD
item1 = Ludwig
item2 = Xyz

SD
item1 = Tamba
item2 = SD_xxx

HH
item1 = chris

But its only printing the first variable of each category..

d.healey

Use Console.print(trace(obj)); to see the contents of the object.

For global objects you can also right click in the script watch table to see the contents.

I did.
So if at line 2 (in your example)= BD
how do i specify the index? Ive tried [0], [1] [2] [3] . It doesnt work..

d.healey

The index of BD?

ten7kur

@d-healey said in Print Object Value for Object Key; not working:

The index of BD?

Looking at the Script Watch Table its line 2. But i think im not understanding something. It should be and is @index = 0??

d.healey

@ten7kur Obj is an object not an array. So obj doesn't have indexes like [0],[1],[2], etc. BD is an array though so BD[0] = "Ludwig".

ten7kur

This post is deleted!

ten7kur

I understand that "Obj" is a object. I thought an object holds arrays....

ten7kur

How can i access the arrays?

d.healey

@ten7kur It does, "BD" is a key and its value is an array.

d.healey

@ten7kur said in Print Object Value for Object Key; not working:

How can i access the arrays?

obj.BD or obj.SD, etc.

keyArray2.push(obj[BD]);? ..ooops typo. I meant :

keyArray2.push(obj[k][BD]);

I cant get the keyArray2 to populate correct, its displaying the fist value from each category.. as before

const var SamplemapList_CAT1 = Content.getComponent("SamplemapList_CAT1");
const var SamplemapList_CAT2 = Content.getComponent("SamplemapList_CAT2");

// viewport list the items
SamplemapList_CAT1.set("useList", true);
SamplemapList_CAT2.set("useList", true);
const var keyArray = [];
const var keyArray2 = [];
const var keyArray3 = [];
    
// put under category
const var names = ["BD_Ludwig","BD_Xyz","SD_Tamba","SD_Xxx","HH_chris"]; 

     

// this will hold the samplenames sorted by category
     var obj = {};

     for(n in names)
         {
         // This splits the string into a list using the given separator
         var sp = n.split("_");

         var drm_category = sp[0];
         var drm_sampleName = sp[1];

         // We can check if the category is already used
         if(isDefined(obj[drm_category]))
             obj[drm_category].push(drm_sampleName); // append to the existing list
         else
             obj[drm_category] = [drm_sampleName]; // create a new list at the key
         }
		 
    for (k in obj)
    {
        //Lists CAT1
        keyArray.push(k);
         Console.print(k);
        
         //List CAT
        keyArray2.push(obj[k][BD]);
        keyArray3.push(obj[k][SD]);
        //keyArray2.push(k[obj]);
        Console.print(obj[k][BD]);
    }
    
 
    
    
// Update the viewports
SamplemapList_CAT1.set("items", keyArray.join("\n"));
SamplemapList_CAT2.set("items", keyArray2.join("\n"));

@ten7kur
Even in something simple like this code below , i cant get "a" to show all its contents; all it prints is "a" and its first value "10" + undefined parameter 0

const var o = {a:[10,11,12], b:14, c:15, d:16}

    for (k in o)
    {    
        Console.print(o[k][a]);
    }

If i do:

const var o = {a:[10,11,12], b:14, c:15, d:16}

    for (k in o)
    {    
        Console.print(o[k]);
    }

Then i get a print out of "[Array] 14 15 16"
What am i not understanding?
Thanks

@ten7kur

so in your simple example:

You have an object called o

it has 4 attributes named a,b,c and d

you need to reference these attributes in the object

Console.print(o.a);

will print "Array"

Console.print(o.a[0]);

will print 10

Console.print(o.b);

will print 14

so if you want to iterate through the attributes of o

const var o = {a:[10,11,12], b:[14,22,77], c:[1,9,6,-415], d:[16,22,11,56]}


    for (k in o)
    {    
        // k will first hold a, then b then c then d
        var key = o[k];
        Console.print(key[0]);
    }

so this will print:
10
14
1
16

so with some better name vars

const var o = {a:[10,11,12], b:[14,22,77], c:[1,9,6,-415], d:[16,22,11,56]}

for (key in o)
{    
    // key will first hold a, then b then c then d
    var attrib = o[key];
    for (val in attrib)
    {
        Console.print(val);
    };
};

    // key will first hold a, then b then c then d
    var attrib = o[key];
    for (val in attrib)
    {
        Console.print(val);
    };
};

Aha, i see.
Console is printing all the values!Great! But going back to my first example, i cant manage to display it in a viewport.
The array "attrib" only shows 1 value "chris"... Why? yet Console prints all??

@ten7kur said in Print Object Value for Object Key; not working:

Aha, i see.
Console is printing all the values!Great!

No. its not, I think you maybe still not quite there...your code:

const var o = {a:[10,11,12], b:14, c:15, d:16}

    for (k in o)
    {    
        Console.print(o[k][a]);
    }

So Console is being asked to print something about o...

o[k][a]

-- so break this down:

o - the object
k - an attribute of o
a - huh?

as you move through your loop K contains the attribute - so first time through
o = your object
k = the first attribute of your object (which first time thru is an attribute called "a")
a = well who knows what this equals but it really should be pointing at an index - its important to realise that even though you've named your attribute "a" in your object theres no way for the code to get at "an attribute called a" unless you explicitly call it - maybe like this:

Console.print(o.a)

in the loop you are running the code has no idea that theres something called "a" in your object

So as you say "all it prints is "a" and its first value "10" + undefined parameter 0"

so Console.print essentially does this:

print o[k] -- so it prints "a"
print o[k][a] -- er there is no attribute called "a" on the output of o[k] so its undefined...so prints undefined...

All of your problems are (as far as I can see) based on not understanding arrays and objects in javascript - stop, slow down, go do an online javascript course (they're free) and you will be much better off...

Aha, i see.
Console is printing all the values!Great!
No. its not, I think you maybe still not quite there...your code:
const var o = {a:[10,11,12], b:14, c:15, d:16}

    for (k in o)
    {    
        Console.print(o[k][a]);
    }
So Console is being asked to print something about o...

o[k][a]

-- so break this down:

o - the object
k - an attribute of o
a - huh?

as you move through your loop K contains the attribute - so first time through
o = your object
k = the first attribute of your object (which first time thru is an attribute called "a")
a = well who knows what this equals but it really should be pointing at an index - its important to realise that even though you've named your attribute "a" in your object theres no way for the code to get at "an attribute called a" unless you explicitly call it - maybe like this:

It is printing all values. Checkout my snippet.
Console.print(val1); prints everything! yet but var attrib only has 1 item, "chris". Thats what i dont understand...

Ok, will do more reading...
