jQuery: some keys of objects cannot be accessed

Question

Using jQuery, I have loaded some data to an object defined by var tmp={}.

Somehow the data will be displayed by console.dir(tmp), but I cannot get some values by accessing it directly (e.g. tmp.val)!

The object I am storing data to is called tmp in the following example. Unfortunately, I cannot present the complete code how the data is gathered since it is too much. What I can present is the output.

console.log(tmp)

$.each(tmp,function(key,val){
    console.log(key);
});

The fist line will display:

Object
  class: "modul7"
  class_name: "Some kind of class name."
  collectionRelevant: 1

The second code will display:

class
class_name

The collectionRelevant is missing.

I know my question is vague.

Has anyone stumbled over something like this? I have no clue anymore in which direction to seek the error.

What will be the output of `console.log( tmp.hasOwnProperty('collectionRelevant') )` ? — Engineer, May 17 '12 at 19:30

I think native JavaScript should be enough for this task.

for( var key in tmp ) {
  // key
  console.log(key);
  // value
  console.log(tmp[key]);
}

That should be `for(var key in tmp)`. Don't wanna be making global variables for no reason :-P – gen_Eric May 17 '12 at 19:29
