how to add key value pair in the JSON object already declared

Question

I have declared a JSON Object and added some key value pair in that like:

var obj  = {}; 

and added some data into it like:

obj = { "1":"aa", "2":"bb" }; 

But I want to add more key value pair in the same object, if I add key value pair same above mentioned then it replace the old one. So could any one please tell me how I can append data in the same JSON Object i.e. obj.

Answer 1

Could you do the following:

obj = {     "1":"aa",     "2":"bb" };   var newNum = "3"; var newVal = "cc";   obj[newNum] = newVal;    alert(obj["3"]); // this would alert 'cc' 

Answer 2

You can use dot notation or bracket notation ...

var obj = {}; obj = {   "1": "aa",   "2": "bb" };  obj.another = "valuehere"; obj["3"] = "cc";
