如何使用Cordova创建子文件夹 [英] How to create subfolder using Cordova

问题描述

我正在使用Cordova，并且尝试在设备上的SD卡的根目录中创建一个文件夹。我使用以下代码创建了文件夹，并在其中添加了文件'login.txt'：

I'm using Cordova and I tried to create a folder to the root of my SD card on a device. I used the following code for create the folder and add a file 'login.txt' inside it:

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

function gotFS(fileSystem) {
   fileSystem.root.getDirectory("citylook", {create: true}, gotDir);
}

function gotDir(dirEntry) {
    dirEntry.getFile("login.txt", {create: true, exclusive: true}, gotFile);
}

function gotFile(fileEntry) {
    // Do something with fileEntry here
    fileEntry.createWriter(gotFileWriter, fail);
}

function gotFileWriter(writer) {
    writer.onwriteend = function(evt) {
        console.log("contents of file now 'some sample text'");
        writer.truncate(11);
        writer.onwriteend = function(evt) {
            writer.seek(0);
            writer.write(testo);
            writer.onwriteend = function(evt){
                console.log("contents of file now '"+testo+"'");
            }
        };
    };
    writer.write("some sample text");
}

function fail(error) {
    console.log(error.code);
}

现在，我需要在 citylook文件夹中创建一个文件夹，所以我尝试过此操作：

Now, I need to create a folder inside "citylook" folder, so I tried this:

function onDeviceReady() {
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onSuccess, null);
}

function onSuccess() {
    fileSystem.root.getDirectory("citylook", {create: true, exclusive: false}, onGetDirectoryWin, onGetDirectoryFail);
    fileSystem.root.getDirectory("citylook/nuovo", {create: true, exclusive: false}, onGetDirectoryWin2, onGetDirectoryFail2);
}

但我无法创建子文件夹。我的代码有什么问题？谢谢。

but I can't create a subfolder. What's is wrong in my code? Thank you.

fileSystem.root.getDirectory("citylook", {create: true}, gotDir);
fileSystem.root.getDirectory("citylook/subfolder", {create: true}, gotDir);

推荐答案

window.resolveLocalFileSystemURL(
        cordova.file.externalDataDirectory,
        function(entry) {
          entry.getDirectory(
            "myNewDirectory",
            { create: true, exclusive: false },
            function(result) {
              alert(JSON.stringify(result));
            },
            onError
          );
        }
      );

我正在使用cordova为Android /数据//文件成功创建一个文件夹。

i'm using cordova create a folder to the Android/data//files success.
