我可以使用 Phonegap/cordova 框架复制目录吗?

Question

我想将一个目录从一个位置复制到另一个位置。我研究我发现复制到API。在该文档中，我从文档中找到了快速示例，如下所示

function win(entry) {
    console.log("New Path: " + entry.fullPath);
}
function fail(error) {
    alert(error.code);
}
function copyDir(entry) {
    var parent = document.getElementById('parent').value,
        newName = document.getElementById('newName').value,
        parentEntry = new DirectoryEntry({fullPath: parent});
    // copy the directory to a new directory and rename it
    entry.copyTo(parentEntry, newName, success, fail);
}

现在我如何混淆源路径变量在哪里，目标路径变量在哪里？任何人都可以为我提供一个很好的例子吗

我希望以下内容对您有所帮助：

var root;
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
    function(fileSystem) {
        root = fileSystem.root;
        // get the directory we want to get within the root directory
        var srcDir = 'srcDir'; 
        root.getDirectory(srcDir, {create: false}, getDirectoryWin, getDirectoryFail);
});
// the directory param should be a DirectoryEntry object that points to the srcDir    
function getDirectoryWin(directory){
    console.log('got the directory');
    // path to the parent directory that holds the dir that we want to copy to
    // we'll set it as the root, but otherwise you'll
    // need parentDir be a DirectoryEntry object
    var parentDir = root;
    // name of the destination directory within the parentDir
    var dstDir = 'dstDir'; 
    // use copyWin/copyFail to launch callbacks when it works/fails
    directory.copyTo(root, dstDir, copyWin, copyFail);
}
function getDirectoryFail(){
    console.log("I failed at getting a directory");
}
function copyWin(){
    console.log('Copying worked!');
}
function copyFail(){
    console.log('I failed copying');
}
