Q&A

Q1:The objects described in Hour 10 included parent and child objects. Can I include child objects in my custom object definitions?
A1: Yes. Just create a constructor function for the child object, and then add a property to the parent object that corresponds to it. For example, if you created a Nicknames object to store several nicknames for a person in the card file example, you could add it as a child object in the Card object's constructor: this.nick = new Nicknames();.
Q2:Can I create an array of custom objects?
A2: Yes. First, create the object definition as usual and define an array with the required number of elements. Then use a loop to assign a new object to each array element (for example, cardarray[1] = new Card();).
Q3:Which browsers support custom objects?
A3: The features described in this hour are included in JavaScript 1.1, and should be supported by Netscape 3.0 or later and Internet Explorer 4.0 and later.
