推荐答案

随着从您提供的链接的例子中，删除的文件名和 uriString中的距离应用的对象，和参数所需要的功能。例如，startDownload将变为：

Following the example from the link you provided, remove the fileName and uriString fields from the app object, and parameterize the needed functions. For example, startDownload will become:

startDownload: function (fileName, uriString) {

    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSystem) {
        fileSystem.root.getFile(fileName, { create: true }, function (newFile) {
            app.downloadFile(uriString, newFile);
        });
    });
},
