Question

I need to read many files in a directory.
I can get files names of directory, but don’t get read the file content

Below is my code

$("#import-offline").click( function(){
            var localFolder = "ico/recebe/importa/";
            window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
                  fs.root.getDirectory(localFolder, {}, function(dirEntry){
                  var dirReader = dirEntry.createReader();
                  dirReader.readEntries(function(entries) {
                        for(var i = 0; i < entries.length; i++) {
                            var entry = entries[i];
                            if (entry.isFile){  // here works
                                var arquivoPath = entry.fullPath;
                                var reader = new FileReader();
                                reader.onloadend = function(evt) {
                                    $("#msgSync").html(evt.target.result);
                                };
                                reader.readAsText(arquivoPath);

                            }
                        }
                  }, fail);
                }, fail);
            });

        });    

    });
