Question

我已经使用cordovaFileTransfer插件下载了csv文件。但是文件在我的设备中不可见。如何访问下载的文件。

代码：-

var stockData = [ { 红色”，值：“＃f00” }， { 颜色：“绿色”，值：“＃0f0” }， { 颜色：“蓝色”，值：“＃00f” }， { 颜色：“青色”，值：“＃0ff” }， { 颜色：“洋红色”，值：“＃f0f” }， { 颜色：“黄色”，值：“＃ff0” }， { 颜色：“黑色”，值：“＃000” } ];

function convertArrayOfObjectsToCSV(args) {
    var result, ctr, keys, columnDelimiter, lineDelimiter, data;

    data = args.data || null;
    if (data == null || !data.length) {
        return null;
    }

    columnDelimiter = args.columnDelimiter || ',';
    lineDelimiter = args.lineDelimiter || '\n';

    keys = Object.keys(data[0]);

    result = '';
    result += keys.join(columnDelimiter);
    result += lineDelimiter;

    data.forEach(function(item) {
        ctr = 0;
        keys.forEach(function(key) {
            if (ctr > 0) result += columnDelimiter;

            result += item[key];
            ctr++;
        });
        result += lineDelimiter;
    });

    return result;
}

$scope.downloadCSV=function(args) {
//alert(JSON.stringify(args))
    var data, filename, link;

    var csv = convertArrayOfObjectsToCSV({
        data: stockData
    });
    if (csv == null) return;

    //filename = args.filename || 'export.csv';

    if (!csv.match(/^data:text\/csv/i)) {
       // csv = 'data:text/csv;charset=utf-8,' + csv;
       csv =  csv;
    }
    //data = encodeURI(csv);

    //link = document.createElement('a');
    //link.setAttribute('href', data);
    //link.setAttribute('download', filename);
    //link.click();




    ionic.Platform.ready(function(){

    var scc=cordova.file.dataDirectory;
    //alert(scc);

      $cordovaFile.writeFile(scc,'sk12.csv', csv, true).then(function(result){
        alert('Success! Export created!'+JSON.stringify(result));
         var url = result.target.localURL;
         var filename = url.split("/").pop();
         var targetPath2 = cordova.file.dataDirectory + filename;
          $cordovaFileTransfer.download(url, targetPath2, {}, true).then(function (result) {   
               $scope.hasil = 'Save file on '+targetPath2+' success!';
                $scope.mywallpaper=targetPath2;


          }, function (error) {
                $scope.hasil = 'Error Download file';
          }, function (progress) {
                $scope.downloadProgress = (progress.loaded / progress.total) * 100;
               // alert("dom "+$scope.downloadProgress);
          });
      }, function(err) {
        alert("ERROR"+JSON.stringify(err));
      });

}） }
