What is the Difference between AJAX and Javascript?

Answer

AJAX is not different from Javascript.
Like , a child can't be differentiated by a mother.
AJAX is a acronym for 'Asynchronous Javascript And XML'.

AJAX is a new approach towards page reloading.

If you want a specific book , you will purchase that book
and not the whole book store.

Similarly if you want a small part of the data in a web page
, you will not go for whole page reload, you woould prefer
to get the data you want.

How can we assign an object in Java Script??

For Example:-
-----------
If i create an object "obj1"
var obj1 = Object();
obj1.name = "hari";

and if i want to assign it to two objects "obj2" and "obj3"
with different names...

obj1.name = "gopi"
obj2 = new Object(obj1);

obj1.name = "raghu"
obj3 = new Object(obj1)

Now ob2.name become to "raghu" from "gopi". WHY?
how to solve the above problem?

Answer

var obj1 = Object();
obj1.name = "hari";

obj1.name = "gopi";
obj2 = new Object(obj1);

//preserving name property of obj2 through obj4
var obj4=new Object();
obj4.name=obj2.name;

obj1.name = "raghu";
obj3 = new Object(obj1);

obj2=new Object(obj4);
alert("obj2 name="+obj2.name+" obj3 name="+obj3.name)
