You will need to use the File Plugin of Crodova to write file to the file system as different Operating System have only certain directories accessible to the Application to read/write.

The code to create the file object and writing will look something like this

window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dir) {
   console.log("got main dir", dir);
   dir.getFile("myfile.csv", {
     create: true
   }, function(file) {
     console.log("got the file", file);
     logOb = file;
     var csv = "";
     //we should have the same amount of name/cookie fields
     var name = "testdata1";
     var cookies = "testdata2",
       csv = csv + "" + name + "," + cookies + "\n";
     console.log("csv-" + csv);
     writeLog(csv);
   });
 });

 function writeLog(str) {
   if (!logOb) return;
   logOb.createWriter(function(fileWriter) {
     fileWriter.seek(fileWriter.length);

     var blob = new Blob([str], {
       type: 'text/plain'
     });
     fileWriter.write(blob);
     console.log("ok, in theory i worked");
   }, fail);
 }
