Hi,<br />
<br />
I am just practising some JS questions.<br />
I need to create a circle object with the Object() constructor and a method that will calculate<br />
its circumference.<br />
<br />
Can you please advise what is wrong with my code:<br />
<br />
&lt;html&gt;<br />
&lt;head&gt;&lt;title&gt;Object object&lt;/title&gt;<br />
&lt;script type=&quot;text/javascript&quot;&gt;<br />
<br />
var circle = new Object(radius);<br />
circle.radius = radius;<br />
circle.calcCircumference;<br />
<br />
function calcCircumference() {<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return (Math.PI*Math.Pow(radius,2<wbr />));<br />
}<br />
<br />
&lt;/script&gt;<br />
&lt;/head&gt;<br />
&lt;body bgColor=&quot;#EOFFFF&quot;&gt;<br />
&lt;script type=&quot;text/javascript&quot;&gt;<br />
alert(circle.calcCircumfer<wbr />ence(3);<br />
<br />
&lt;/script&gt;<br />
&lt;/body&gt;<br />
&lt;/html&gt;<br />
<br />
thanks

Hi,

I am just practising some JS questions.
I need to create a circle object with the Object() constructor and a method that will calculate
its circumference.

Can you please advise what is wrong with my code:

<html>
<head><title>Object object</title>
<script type="text/javascript">

var circle = new Object(radius);
circle.radius = radius;
circle.calcCircumference;

function calcCircumference() {
	return (Math.PI*Math.Pow(radius,2));
}

</script>
</head>
<body bgColor="#EOFFFF">
<script type="text/javascript">
alert(circle.calcCircumference(3);

</script>
</body>
</html>

please help with JS object

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
