Using a variable for a Javascript object key

I can’t figure out how I am messing this up.

My code gives me the error:

invalid property id

Code:

 return  { this.Obj.itemid :
               {  Color : this.Obj.color,
                  Name : this.Obj.name,
                  Year : this.Obj.year
                }
           };

I need to return these hashes as an array (thus the return), but no matter what I do, it either returns the error above, or the var reference is stringified. I can’t actually get the dynamic js value in there as a key.

I’ve tried this:

" + this.Obj.itemid + "

and this:

var itemid = this.Obj.itemid;
return { itemid : {
         //etc..
    }}

Any ideas?

The problem is that you can’t use this.Obj.itemid in that way.

Instead, try something like:

var ret={};
ret[this.Obj.itemid]=
   {
      Color : this.Obj.color,
      Name : this.Obj.name,
      Year : this.Obj.year
   };
return ret;
