Why are the properties of this object undefined? Javascript

Question

Attribute is an object in this form:

   var attribute = {
    AttributeId: attributeId,
    EntityId: entityId,
    AttributeDBName: attributeDbName,
    AttributeDisplayName: attributeDisplayName,
    IsSearchable: isSearchable,
    IsDeleted: isDeleted,
    IsVisible: isVisible,
    AttributeTypeId: attributeTypeId,
    Description: description,
    IsSystem: isSystem,
    IsActive: isActive,
    IsUnique: isUnique,
    IsRequired: isRequired,
    IsPersistent: isPersistent,
    DefaultValue: defaultValue
};

That attribute then gets passed to this function along with the ID of a grid:

function AddAttributeToGrid(attribute, gridId) {

    console.log(attribute); //Works! Displays the attribute.

    var id = a.attributeId;

    console.log(id);//UNDEFINED? WHAT?   

}

If I create a global variable (let's call it 'tempAttribute') and set it inside of AddAttributeToGrid, like so:

 function AddAttributeToGrid(attribute, gridId) {
    tempAttribute = attribute
}

I can then access the properties of tempAttribute...

Why can I not get the data from the properties? What is going on?

The property of attribute is AttributeId, not attributeId.

JavaScript is case sensitive.

But this assumes you initialized your object with a defined attributeId to start with. This is not clear in your code.

i think you have

var id = a.attributeId;

instead of

var id = attribute.AttributeId;

inside the AddAttributeToGrid function definition

Close :) Turns out it was just a damn capitol letter instead of lowercase!
