使用PhoneGap将文件从www复制到'Documents'

Question

我正在尝试将存储在phonegap文件夹(www/default_files/file.txt)中的文件复制到iOS中的文档文件夹,到目前为止我得到的是:

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys)
{
  fileSys.root.getFile("file.txt", null, function(theFile){ // file exist don't do anything},
    function(error)
    {
      // file does not exist, so copy it
      fileSys.copyTo(fileSys.root.fullPath, "www/default_files/file.txt",
        function success(entry)
        {
          console.log("Success: " + entry);
        },
          function error(entry)
        {
          console.log(entry);
        });
  });
}, fileError);

fileSys.root.fullPath包含正确的Documents Path,问题是如何访问www文件夹...

有任何想法吗？

这段代码适用于iOS.此函数将数据库文件的副本从/ www文件夹实现到/ Documents文件夹.

function copyBase(){
    var wwwPath = window.location.pathname;
    var basePath = 'file://'+ wwwPath.substring(0,wwwPath.length-10);
    window.resolveLocalFileSystemURL(basePath+'myDB.db', 
        function(fileDB){
            console.log('success! database was found')  
            window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onSuccess, null);

                function onSuccess(fileSystem) {
                    var documentsPath = fileSystem.root;
                    fileDB.copyTo(documentsPath, 'myDB.db',
                    function(){
                        console.log('copying was successful')
                    }, 
                    function(){
                        console.log('unsuccessful copying')
                    });
                }
        }, 
        function(){
            console.log('failure! database was not found')
        });
}
