In-Depth Information
1. Create a circle object with the Object() constructor and a method that will cal-
culate its circumference.
2. Write a function that will create a clock object.
a. It will have three properties: seconds , minutes , and hours .
b. Write two methods: setTime() to set the current time and displayTime() to
display the time.
c. The user will be prompted to select either a.m./p.m., or military time. The
value he or she chooses will be passed as an argument to the displayTime()
3. The output will be either
14:10:26 or 2:10:26 pm
depending on what argument was passed to the display() method.
4. The following function acts as a constructor to create an Employee object.
Use this function to create three new employees. Set the properties and print
the employees' names. Add a phone property to this function.
<script type="text/javascript">
function Employee(){
var = name;
this.getName = function(){
this.setName = function(name){ = name;
5. Create an object literal called Customer. The Customer will have
properties: a name, gender, photo, and occupation. There will be one method
called showCustomer() . The user will be prompted for each of the property val-
ues. Use the showCustomer() method to display the data in an HTML table.
6. Using JavaScript prototyping, extend the Employee (Exercise 4). Create two
new subclasses from the Employee: a Salesman and a Manager class. Use a pro-
totype to create a salary property for the new employees ( setSalary , getSalary ),
and a setRaise() method to add 15 percent to the salary. Check to see if each of
the new Employees is an instance of the Employee class.
