File-related Dialogs

You can use Open Dialog and Save Dialog to allow users to choose files or directories.

Open Dialog

Following is an example of Open Dialog for choosing a text *.txt file.

var FileSystem = require("filesystem/FileSystem");

FileSystem.showOpenDialog(false, false, "Select a text file...", null, ["txt"], function (err, files) {
    if (!err) {
        if (files.length > 0) {
            // User selected one or more files
        } else {
            // User canceled
        }
    } else {
        // Handle error
    }
});

Save Dialog

Following is an example of Save Dialog for getting a file name.

var FileSystem = require("filesystem/FileSystem");

FileSystem.showSaveDialog("Save text as...", null, "Untitled.txt", function (err, filename) {
    if (!err) {
        if (filename) {
            // User selected a file name
        } else {
            // User canceled
        }
    } else {
        // Handle error
    }
});
