How would you access Object properties from within an object method?

it helps some times This has religious war potential, but it seems to me that if you're using a getter/setter, you should use it internally as well - using both will lead to maintenance problems down the road (e.g. somebody adds code to a setter that needs to run every time that property is set, and the property is being set internally w/o that setter being called).

Any of those help The second time, self.callback passes the reference to the function $.Comment.prototype.callback. As with all Javascript functions, this doesn't carry a binding to the same "this" object (the same reason why you are storing this and using self above, but you are using it overzealously).
Basically, if a function is used within a different context, this no longer refers to the same thing. The first instance above, you store this as self, and then invoke self.callback(). This invokes callback with self as its this object. The second instance simply passes callback the function (without context) to be called. When it is called then, this is lost.

I think the issue was by ths following , Your problem is in main not attack. You set your access modifier for Enemy::setAttackPower(int) and Enemy::getAttackPower() to protected. That means these methods are treated as private unless if you're inside a class that extends Enemy.
That means when you are in main it can't access ninjaObj.setAttackPower(23) because main is outside the scope of any object.

With these it helps You can use the Function.prototype.bind or jQuery $.proxy method for setting the this value of the function:

removeListItem: function(event) {
    var element = event.currentTarget;
    // ...

this will help The problem is that ProductEntry you were trying to create is not a valid JSON.
Try this code:
code :
    var ProductEntry = [{Title: 'ProductTitle', Description: 'Description', Hashtags: 'Hashtags',
                Picture1: 'Picture1', Picture2: 'Picture2', Picture3: 'Picture3', Start: 'startdate', ETA: 

            localStorage.setItem("Product", JSON.stringify(ProductEntry));

        var SearchQuery = document.getElementById("SearchField").value; 
        var storageObject = JSON.parse(localStorage.getItem("Product"));

I wish this help you The addSelectionCallback method has an optional parameter for userData pointer. There you should send the object instance, which you will receive then in your callback.
Inside the method, you can typecast to the correct object type and do the actual work with the object instance.
code :
void MyClass::selCallback(void* userData, SoPath* selPath) {
    static_cast<MyClass *>(userData)->classProperty = 3;

MyClass myInstance;
selNode->addSelectionCallback(MyClass::selCallback, &myInstance);
