Consider i am having an object "req".

When i use console.log(req) i get

Object { term="s"}

My requirement is to append an value with the existing object.

My expected requirement is to be like this:

Object { term="s", st_id = "512"}

Is it possible to do the above?

If yes, how ?

Thanks in advance..

There are several ways to do it;

Plain javascript:

var req = { "term" : "s" };
req.st_id = "512";

Because javascript objects behaves like associative arrays* you can also use this:

var req = { "term" : "s" };
req["st_id"] = "512";

jQuery way $.extend():

var req = { "term" : "s" };
$.extend(req, { "st_id" : "512" });

You can do this in a couple of ways:

req.st_id = "512";

or

req["st_id"] = "512";

The second of these is especially useful if the variable name is dynamic, e.g. a variable could be used instead of the string literal:

var key = "st_id";
req[key] = "512";

Yes this is possible, to add properties to a value simply use the following syntax:

req.st_id = "512";
