执行自动保存与Adobe AIR使用了弹出保存对话框开幕

问题描述

我有一个AIR应用程序，我想实现一个自动保存功能。目前，我有使用定时器来检查我的应用程序的当前活动文件的状态，那么如果文件更改到一个新的文件，该服务会检查当前文件名，如果已经改变，那​​么该文件已经修改的服务。当发生这种情况我想执行一个自动保存，这是我可以做的，但问题是，保存弹出保存对话框打开时，保存被调用，这就是我所说的保存功能：

I've an AIR app that I'd like to implement a auto-save functionality. Currently I have a service that uses a timer to check the status of the current active file in my app, then if the file changes to a new file, the service checks the current file name if that has changed then the file has changed.When this happens I want to perform a auto-save, which I can do but the problem is that the save popup save box opens when the save is called, this is how I call the save function:

var文件：文件= File.userDirectory.resolvePath（文件路径）;file.save（jsonToExport）;

var file:File = File.userDirectory.resolvePath( filepath );file.save( jsonToExport );

有没有办法来调用没有一个弹出框打开保存（）函数？

Is there a way to call the save() function without a popup box opening?

推荐答案

而不是使用文件的保存方法，请尝试使用FileStream直接写入文件：

Rather than using the File's save method, try using a FileStream to write the file directly:

var file:File = File.userDirectory.resolvePath( filepath );

//Instantiate new file stream
var fs:FileStream = new FileStream();

//add optional event listener to do some action once finished
fs.addEventListener(Event.CLOSE, fileWrittenComplete);

//open the file in write mode
fs.openAsync(file, FileMode.WRITE);

//write your data to file
fs.writeUTFBytes(jsonToExport);

//close the file stream
fs.close();
