Constructing json object using javascript

I am facing issues while constructing an object using javascript. I want this:

{
    "p_id": "2",
    "p_name": "weblogic",
    "ip_list": [
        {
            "ip_id": 2690
        },
        {
            "ip_id": 2692
        },
        {
            "ip_id": 2693
        }
    ]
}

Below is the javascript code that I am using to get the data into the object:

var ipArray = [];
secTagJSON.p_name = "weblogic";
secTagJSON.p_id = "2";
for (var index=0; index < selectedArray.length; index++){
    secTagJSON.ip_list.push("ip_id": selectedArray[index]);
}

I am able to construct the properties for p_id and p_name but struggling to create the the ip_list. Please let me know how to get this constructed using javascript.

Code for posting to the server:

var ipArray = [];
secTagJSON.p_name = "weblogic";
secTagJSON.p_id = 2;
for (var index=0; index < selectedArray.length; index++){
 secTagJSON.ip_list.push({"ip_id": selectedArray[index]});
}
console.log (secTagJSON);
console.log (JSON.stringify(secTagJSON));
 $http.post("http://server:port/api/v1/tags").
    success(function(data) {
      console.log (data)
    });

Try:

secTagJSON.p_name = "weblogic";
secTagJSON.p_id = "2";
secTagJSON.ip_list = [];
for (var index=0; index < selectedArray.length; index++){
 secTagJSON.ip_list.push({"ip_id": selectedArray[index]});
}

you forgot your {} around "ip_id": etc... You also need to declare that ip_list is an array. Your ip_list is an array of objects. I would guess that your script was not running as it was.

Posting to your server you should use:

$http.post('server:port/api/v1/tags', secTagJSON).sucess(...

Simply do this: 

var obj = { ip_list: [] };

obj.p_name = "weblogic";
obj.p_id = "2";

for (var i = 0, j = selectedArray.length; i < j; i++)
   obj.ip_list.push({ ip_id: selectedArray[i] });

Note that your ip_list is actually an array of objects. So, when you iterate over it, remember that each var item = json.ip_list[i] will return an object, that you can access its properties using: item['ip_id'].

Note that obj is an Javascript object, it is not an JSON. If you want the JSON, you can use JSON.stringify(obj). This will return your JSON (string).

Hope I've helped.
