Sending a variable to a function in JavaScript (winJs) from a different function

Greetings! Currently, I am developing a Windows 8 app using Java Script.

function fetchFromLiveProvider(currentList, globalList,value) {
    feedburnerUrl = currentList.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) {
                 var jsonData = JSON.parse(result.response);
                    //console.log(JSON.stringify(jsonData));
                 var entries = jsonData.responseData.feed;
               });
    }
function setOther(entries){ 
       //some code here
    }

My goal is to pass the entries in the fetchFromLiveProvider function to another function named setOther(entries){}. Any assistance in achieving this would be greatly appreciated. Thank you!

Answer №1

By utilizing the promise returned by WinJS.xhr, you can implement the following approach: 

var entriesPromise = function retrieveFromLiveProvider(currentList, globalList, value) {
    feedburnerUrl = currentList.url,
    feedUrl = "http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&output=json&num=999&q=" + encodeURIComponent(feedburnerUrl);
    return WinJS.xhr({
        url: feedUrl,
        responseType: "rss/json"
    });
}

function processEntries(entries) {
    entries.done(function handleResponse(result) {
        var jsonData = JSON.parse(result.response);
        //console.log(JSON.stringify(jsonData));
        var items = jsonData.responseData.feed;

        //additional code goes here
    })
}

processEntries(entriesPromise);
