Passing Some Argument To The Callback Function Of Winjs Xhr

In Windows 8, I am using WinJs.xhr in a loop to download some content, and as it arrives afterward to the 'done callback', I would like to pass an argument to retrieve the element

Solution 1:

You'll need to capture it in a closure, which with vanilla for loops/iteration is a pain:

for (var k = 0 ; k < 9; k++) {
    (function(item) {
        var url;
        var title = item.name;
        if (title != null)
            url = monUrl+ title;

        WinJS.xhr({ url: url, responseType: "responseXML" }).done(function complete(result) {
            // I would like to retrieve the right title here for example
            var dataArray = new Array();
            var xml = result.responseXML;
            /* use your title property here */
        });
    })(dataArray[k]);
}
