Concatenate Json strings

Question

I need to concatenate two Json strings. The code for the first one is below.

var output = {
    Studios: $('#btnStudios button').map(function() {
        return $(this).val();
    }).get(),
    Platform: $('#btnplatforms button').map(function() {
        return $(this).val();
    }).get(),
    VODEST: $('#btnvodest button').map(function() {
            return $(this).val();
        }).get(),
    SDHD: $('#btnsdhd button').map(function() {
            return $(this).val();
        }).get(),
    Category: $('#btncategory button').map(function() {
            return $(this).val();
        }).get(),
    Genre: $('#btngenre button').map(function() {
            return $(this).val();
        }).get(),
};
$('.list').html(JSON.stringify(output));

And the result is:

{"Studios":["warner","tf1","gaumont","pathe","studiocanal","francetv","m6snd"],"Platform":["orange","itunes","sfr"],"VODEST":["vod","est"],"SDHD":["sd","hd"],"Category":["film","tv","others"],"Genre":["thriller","action","drama","horror"]}

I need to add this string to it:

var per = {Period: {"From":["W6"],"To":["W18"]}}

How would I go about doing this?

"I need to add this string to it:" - thats not a string, its another javascript object! — Jamiec

The first string yes. The second string i am not sure about(The one wich i want to add to the first one). You could correct me if there is any error. @Kobi — Tauseef Hussain

If you are using jQuery, you can use $.extend

$.extend(output, per);

before you call JSON.stringify(output).

This will copy all properties from per to output.

You can also do that manually:

output.Period = per.Period;

There is no reason to work with strings here - you can manipulate the JavaScript object, and convert them to a JSON string when you're done. If you do have a string, you can always parse it to an object using:

var output = JSON.parse(firstString);

But again, you could have done that better.

This is a good answer, but the first part assumes you're using jQuery (not tagged in original question).

@Jamiec - You are right. I'm sure $('#btnStudios button').map().get() is jQuery, but I am assuming.

Ha, didnt notice that. I think we can safely assume the OP should have been tagged jQuery

Works perfect. Thank you so much. String,Array,Object very confusing. Need to work harder :)

One option would be to create a new object and add a property to store the data you need?

var per = {Period: {"From":["W6"],"To":["W18"]}};
per.output = output;
$('.list').html(JSON.stringify(per));
