Javascript 无法在ionic中下载动态图像

嘿，我正在创建一个应用程序，其中动态图像应该从网上下载，但有些人无法下载请检查下面的代码，给出一些下载建议，并告诉如何在ngcordova的社交共享插件中传递动态图像链接

 $

scope.downloadImage = function() {
            $http.get('http://sabkideal.com/phpapi_/cashback.php').success(function(response) {
      $scope.data = response;

       for (var i=0 ;i <response.length; i++)
       {
        var url = response[i].image;
        var deal = response[i].id;
        //url showing the same url every time i click and not jumping to next statement when click on send image download .
       console.log(deal);

      console.log(url);

      var filename = url.split("/").pop  ;

 console.log(filename);

      var     targetPath = encodeURI(cordova.file.dataDirectory + fileName);
       console.log(targetPath);

    var   options = {};
       var  trustHosts = true;

        }


                $cordovaFileTransfer.download(url, targetPath, options, trustHosts)
      .then(
        function(result) {
          alert('Download success');
          refreshMedia.refresh(targetPath);
        },
        function(err) {
          alert('Error: ' + JSON.stringify(err));
        },
        function(progress) {
          // progressing download...
        })

});


     }
