Basics of Javascript class and object

JavaScript Classes and Objects

     The following example is explain you to learn about basics of javascript classes and objects. In the following example we have created a variable funvar including fun1 and fun2 functions.

var funvar=function(A)
{
 alert(A);
 this.fun1=function()
 {
  alert("This function call without argument");
 },
 this.fun2=function(arg1)
 {
  alert(arg1);
 }
}

     When we create a object for the funvar variable, that will automatically call and inside defined functions are initialized.

var ObjVar=new funvar("Constructor call creating time");

     After then if we want to  call that function we can call it using created object variable (ObjVar).

ObjVar.fun1();
ObjVar.fun2("Function 2 Arugument");
