Q: Comment spécifier storage = e.storageVolume.rootDirectory.nativePath?

var remoteFile = 'http://www.CompanyName.com/ClientName.txt'; 

jQuery(function($){ 
    air.StorageVolumeInfo.storageVolumeInfo.addEventListener(air.StorageVolumeChangeEvent.STORAGE_VOLUME_MOUNT, onVolumeMount); 
    air.StorageVolumeInfo.storageVolumeInfo.addEventListener(air.StorageVolumeChangeEvent.STORAGE_VOLUME_UNMOUNT, onVolumeUnmount); 

    var PluggedIn = false; 
    var volumes = air.StorageVolumeInfo.storageVolumeInfo.getStorageVolumes(); 
    for (var i = 0; i < volumes.length; i++) { 
     if (volumes[i].isRemovable) { 
      if (volumes[i].name == 'COMPANYNAME') { 
       PluggedIn = true; 
       $('#content').append('I see you already have CompanyName plugged in!'); 
       var myNativePath = volumes[i].rootDirectory.nativePath; 
       var storage = 'desktopDirectory'; // myNativePath 
       downloadFile(remoteFile, storage); 
      } else { 
       $('#content').append('What you have plugged in is not CompanyName.'); 
      } 
     } 
    } 
    if (!PluggedIn){ 
     $('#content').append('<h1>Please insert your CompanyName card.</h1>'); 
    } 

}) 

function onVolumeMount(e) { 
    if (e.storageVolume.isRemovable) { 
     $('#content').html('<h1>Thank you</h1>'); 
     if (e.storageVolume.name == 'COMPANYNAME') { 
      var myNativePath = e.storageVolume.rootDirectory.nativePath; 
      var storage = 'desktopDirectory'; // myNativePath 
      downloadFile(remoteFile, storage); 
     } else { 
      $('#content').append('<p>The card you just plugged in is not CompanyName.</p>'); 
     } 
    } else { 
     $('#content').append('<p>This device is not removable</p>'); 
    } 
} 

function onVolumeUnmount(e) { 
    $('#content').html('<h1>Goodbye!</h1>'); 
} 

function downloadFile(remoteFile, storage){ 
    var fn = remoteFile.match(/[a-z0-9-+\._]+?$/i); 
    var myFile = air.File[storage].resolvePath(fn); 
    var myURLStream = new air.URLStream(); 
    myURLStream.addEventListener(air.Event.COMPLETE, function(e){ 
     var myByteArray = new air.ByteArray(); 
     myURLStream.readBytes(myByteArray, 0, myURLStream.bytesAvailable); 
     var myFileStream = new air.FileStream(); 
     myFileStream.openAsync(myFile, air.FileMode.WRITE); 
     myFileStream.writeBytes(myByteArray, 0); 
     myFileStream.close(); 
    }); 
    myURLStream.load(new air.URLRequest(remoteFile)); 
} 

Answer 1

var myFile = new air.File("file:///" + storage).resolvePath(fn);
