javascript - Can I convert many rss feeds to single JSON file? -

i working windows 8 app using java script

i have few rss feeds, like:

1. http://dmadmin.dailymirror.lk/index.php?option=com_ninjarsssyndicator&feed_id=16&format=raw

2. http://dmadmin.dailymirror.lk/index.php?option=com_ninjarsssyndicator&feed_id=17&format=raw

following function each rss feed , convert json object..but want rss feed 1 json object. (there 2 rss feeds. after function call gave me 2 separate json objects. want 1 object)

    (x = 0; x < listoffeed.length; x++) {         //loop x start         feedburnerurl = listoffeed[x].url,             feedurl = "http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&output=json&num=999&q=" + encodeuricomponent(feedburnerurl);          winjs.xhr({             url: feedurl,             responsetype: "rss/json"         }).done(function complete(result) { //result = [object xmlhttprequest]  requested urls                                                                                                var jsondata = json.parse(result.response);  //jsondata = [object object] create object             var entries = jsondata.responsedata.feed.entries; //entries = [object object][object object][object object]......              entries.foreach(function (entry) { // process entries...                                                 console.log('{"title" :"' + entry.title + '","date":"' + entry.publisheddate + '"},');                                       });         });     }  //loop x finish } 

1. listoffeed = array of rss url.
2. entries = each object in full json object (there 25 items inside 1 url).
3. jsondata = json format of each url. got two.but want 1 json object these 2 urls.

thank help...

you can use array.concat() join entries arrays. can track number of outstanding requests , process entries when reaches 0. like:

var allentries = []; var pendingrequestcount = listoffeed.length;  var onrequestfinished = function() {   pendingrequestcount--;    if (pendingrequestcount === 0) {     allentries.foreach(function (entry) { // process entries...                                       console.log('{"title" :"' + entry.title + '","date":"' + entry.publisheddate + '"},');                               });   } };  (x = 0; x < listoffeed.length; x++) {   ... // same before   }).done(function complete(result) {     var jsondata = json.parse(result.response);       var entries = jsondata.responsedata.feed.entries;       allentries = allentries.concat(entries);      onrequestfinished();           }); }  //loop x finish 

you should handle failed requests , call onrequestfinished function well.
