Add method to JavaScript object

We can add a method to JavaScript object. First define a method and then assign that method as a property to object.

Example:

<html>
<body>
<script> 
function stuClassName(className){  
this.className=className;     
}  
function Student(name,rollNo){  
this.name=name;  
this.rollNo=rollNo; 
this.stuClassName= stuClassName;  
}  
var student=new Student("Jai", "MCA/07/06"); 
student.stuClassName("MCA Final");
document.write("Name: " +student.name + "</br>");  
document.write("RollNo: " + student.rollNo + "</br>");  
document.write("Class: " + student.className);      
</script>  
</body>
</html>
