Same file keep downloading in phonegap

Error in checking the file.

I have use one code. But i think there is some problem. The file got stuck to one file. And always keep dowloading the same file.

here is how i code this. Here in the below code. I am trying to download the images to local sdcard. If the file is already available i dont want it to download. And if not, then download. But it seems its just keep repeat download the same file. 

function appReady(datadira){



                    $(".gallery").html("Ready to check remote files...");
                    $.get("http://www.pankhida.com/main/?json=get_page&page_id=115&callback=?", {}, function(res) {
                        if (res.page.attachments.length > 0) {
                            $(".gallery").html("Going to sync some images...");
                            for (var i = 0; i < res.page.attachments.length; i++) {
                                if (knownfiles.indexOf(res.page.attachments[i].url) == -1) {
                                    //alert("need to download " + res[i]);
                                    var ft = new FileTransfer();
                                    var fullPath = res.page.attachments[i].url;
                                    var filename = fullPath.replace(/^.*[\\\/]/, '');
                                    var dlPath = DATADIR.toURL() + "/" + filename;
                                    var uri= res.page.attachments[i].url;

                                    uri = encodeURI(uri);

                                    //console.log("downloading crap to " + dlPath);
                                    window.resolveLocalFileSystemURL(DATADIR.toURL() +"/"+ filename, appStart, function(){
                                            ft.download(uri, dlPath, function(e){
                                                //renderPicture(e.toURL());
                                                alert("Successful download of "+e.toURL());
                                            }, onError, true);


                                        });





                                }
                            }
                        }
                        $(".gallery").html("");
                    }, "json");

                }

I am using window.resolveLocalFileSystemURL which i got from this URL http://www.raymondcamden.com/2014/7/1/Cordova-Sample-Check-for-a-file-and-download-if-it-isnt-there.

Please suggest where i am wrong. Or any correct code will be really helpful.

It has to do with the closure inside resolveLocalFileSystemURL.The value of ft ends up being the last one used from the loop. Try changing

for (var i = 0; i < res.page.attachments.length; i++) {

to

res.page.attachments.forEach(function(attachment) {

and the last } to }).

Inside the loop, use attachment instead of res.page.attachments[i].
