I need help with my JavaScript project.

CMPS $162$: Module $7$ Programming Project

$//---------//$

$//$ Objects $//$

$//---------//$

console.log$("$Objects$")$;

$//1.$ Complete the implementation of the Circle object that has methods to

$//$ calculate the area and circumference. You can find a start of the code

$//$ and how the object is supposed to be used below.

$//$ NOTE: that the initial code has several lines commented out that

$//$ you must complete.

$//$ HINT: use the Math.PI to get the value of Pi$.$

$//$ Google how to calculate the area and circumference of a circle if

$//$ you do not recall.

$//$ Round to the nearest $100$th e$.$g$.$ n$.$nn

function Circle$($radius$)\{$

$//$ Replace the question marks to complete the constructor

$//$

$//$ this.? $=?$;

$//$

$//$ implement getArea$()$ method

$//$

this.getArea $=$ function $()\{$

$//$ Your code goes here

$\}$

$//$ implement a getCircumference$()$ method

$//...$

this.getCircumference $=$ function $()\{$

$//$ Your code goes here

$\}$

$\}$

$//$ create the Circle object

var circle $=$ new Circle$(10)$;

$//$ calculate area, not working yet!

var area $=$ circle.getArea$()$;

console.log$($area$)$;

$//$ calculate circumference, not working yet!

var circumference $=$ circle.getCircumference$()$;

console.log$($circumference$)$;

$//2.$ Write the same implementation for a rectangle. Note that the constructor

$//$ takes two parameters in this case: width and height. There should be two

$//$ methods, getArea and getPerimeter.

$//$

$//$ Like exercise $1,$ instanciate a rectangle object using the values width$=10$

$//$ and height $=5$ then log the area and perimeter to the console.

$//-----------------//$

$//$ Browser Control $//$

$//-----------------//$

console.log$("$Browser Control"$)$;

$//1.$ Create a function that:

$//(1)$ Opens a popup window that covers roughly one quarter of the current

$//$ browser.

$//$ a$.$ You will need get the window's outer height and outer width, divide

$//$ them each by two, and then open a new window using the calculated height

$//$ and width values.

$//$ b$.$ The function should accept an arguement called url. The value of

$//$ this argument will be the url of the web page that opens in the popup.

$//$ c$.$ Add an onclick event to the button below to execute the pop$-$up

$//$ function. Pass a specific URL in the call.

See console!
