How do I share a javascript object between different pages in Adobe AIR?

//write an Object to a file
private function writeObject():void {
    var object:Object = new Object();//create an object to store
    object.value =  asObject.text; //set the text field value to the value property
    //create a file under the application storage folder
    var file:File = File.applicationStorageDirectory.resolvePath("myobject.file");
    if (file.exists)
        file.deleteFile();
    var fileStream:FileStream = new FileStream(); //create a file stream
    fileStream.open(file, FileMode.WRITE);// and open the file for write
    fileStream.writeObject(object);//write the object to the file
    fileStream.close();
}
