U can easily do that its very easy

    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccessUpload, fail);

    function onFileSystemSuccessUpload(fileSystem) {
     // get directory entry through root and access all the folders
             var directoryReader = fileSystem.root.createReader();

    // Get a list of all the entries in the directory
    directoryReader.readEntries(successReader,fail); 

          }

      function successReader(entries) {
        var i;
        for (i=0; i<entries.length; i++) {
           //alert(entries[i].name);
           if(entries[i].isDirectory==true)
           {
             var directoryReaderIn = entries[i].createReader();
            directoryReaderIn.readEntries(successReader,fail); 

           }

            if(entries[i].isFile==true)
             {
          entries[i].file(uploadFile, fail);
           }
        }
    }; 

 function uploadFile(file) {
var target=""; //the url to upload on server
     var ft = new FileTransfer(),path = "file://"+ file.fullPath,name = file.name;
                ft.upload(path, target, win, fail, { fileName: name });
               // var ft = new FileTransfer();
              //ft.upload(file.fullPath, target, win, fail, options);


            function win(r) {
                alert("Code = " + r.responseCode);
               alert("Response = " + r.response);
                alert("Sent = " + r.bytesSent);
            }

            function fail(error) {
                alert("An error has occurred: Code = " + error.code);
            }
}

用這個

navigator.camera.getPicture(successFn, errorFn, { quality: 50,
    destinationType: navigator.camera.DestinationType.FILE_URI,
    sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY,
    mediaType: navigator.camera.MediaType.ALLMEDIA  });

這將打開選項，您可以選擇文件，選擇一個將在successFn中為您提供文件的名稱和路徑
