Why is Firebug displaying an inaccessible JavaScript object property?

I am struggling to access the content of an object and can't seem to figure out why. It seems like maybe the properties that Firebug shows the object has are not actually there, or I might just be using the wrong syntax to access them.

Here is the function in question:

function(userData) {
    console.log(userData);   // statement 1
    console.log(userData.t_nodecontent); // statement 2
}

When running this function, FireBug displays the data for statement 1 but returns undefined for statement 2. (Note: Previously mentioned seeing unknown which was incorrect)

Could there be something obvious that I am missing in trying to reference the value of t_nodecontent? I'm feeling quite lost and confused about this.

Answer №1

unknown refers to a Host Object, similar to those created by ActiveXObject in Internet Explorer.

If the property did not exist, you would receive undefined

Therefore, you are indeed accessing its property, but it belongs to a type not specified by ECMAScript.

Answer №2

Give this a shot and see what it spits out:

for(let item in userInfo){
   console.log(item, userInfo[item]);
}

Answer №3

The issue lies in the userData variable being interpreted as [userData]. Make sure to access userData[0] instead. This situation has happened to me previously (most recently today with an object property of a Dojo.Data item)... When an object is passed within an array, Firebug shows the first element of the array rather than the entire array.
