Application handler

Information

A JavaScript library that handles path maps that direct control to handlers, along with the query string parameters.

Recommended use is for supporting paths in the hash part of the address bar. You can do this using a hash history library (such as Hash or the jQuery hash plugin) and call the exec() method when the hash changes.

Example

var UserHandler = Application.handler(function (username, section) {
    alert('Hi ' + username + '!');
    if (section) alert('Showing ' + section + ', page ' +
                       this.get_param('page', 1));
});

var HomeHandler = Application.handler(function () {
    alert('Home!');
});

var app = new Application([
    ['^home$', HomeHandler],
    ['^user/([^/]+)(?:/([^/]+))?$', UserHandler]
]);

app.exec('user/bob/articles?page=2');
// Handler UserHandler will be found (because the pattern matches), and
// then be used like this:
// var handler = new UserHandler(app, 'user/bob/articles?page=2',
//                               'user/bob/articles',
//                               ['bob', 'articles'], {page: '2'});
// handler.run('bob', 'articles');

The above example will open a dialog with the text "Hi bob!", followed by another dialog with the text "Showing articles, page 2". Experiment with the app.exec(...) call!

Example 2 (using Hash and jquery.hash)

// Create application for handling the site.
var app = new Application([
    ['^$', HomeHandler],
    ['^project/([^/]+)$', ProjectHandler],
    ['^.*$', NotFoundHandler]
]);

// Set up application to use the hash as its path.
$(document).hashchange(function (e, hash) {
    app.exec(hash);
});

// Enable the hash library.
$.hash.init();

Note that in the above code, the handlers haven't been included. The example code is only to show how to set up the Application library to use the Hash library with the jQuery hash plugin.
