I would suggest utilizing the resolveLocalFileSystemURL method provided by PhoneGap's file plugin. You can then use the cordova.file.applicationDirectory property to access where your www folder is located.

Make sure you install the plugin: $ cordova plugin add org.apache.cordova.file

Then you could use an object such as the following to parse the files and do whatever is needed:

var FileManager = {

  /**
   * Execute this.entryHandler against all files and directories in phonegap's www folder
   */
  run: function () {

    window.resolveLocalFileSystemURL(
      cordova.file.applicationDirectory + 'www/',
      this.directoryFoundHandler,
      this.errorHandler
    );

  },

  /**
   * The directory has been successfully read.  Now read the entries.
   *
   * @param {DirectoryEntry} directoryEntry
   */
  directoryFoundHandler: function (directoryEntry) {

    var directoryReader = directoryEntry.createReader();

    directoryReader.readEntries(
      this.entryHandler,
      this.errorHandler
    );

  },

  /**
   * Files were successfully found.  Parse them!
   *
   * @param {Array.} entries
   */
  entryHandler: function (entries) {

    entries.forEach(function (entry) {

      // Deal with your files here
      if (entry.isDirectory) {
        // It's a directory might need to loop through again
      } else {
        // It's a file, do something
      }

    });

  },


  /**
   * @param {FileError} error
   */
  errorHandler: function (error) {

    console.log("ERROR", error);

  }

};
