AppSuite:Wizard framework

Wizard/Tour framework

App Suite UI provides a simple but flexible framework to implement wizards and guided tours. The essence of both a wizard and a tour is a set of steps the end-user walks through. Usually a step is a smaller modal popup.

Simple example

The starting point is the "Wizard" (or "Tour") class defined in io.ox/core/tk/wizard.js. A simple example:

 
require(['io.ox/core/tk/wizard'], function (Tour) {
   new Tour()
   .step()
       .title('Welcome')
       .content('Lorem ipsum dolor sit amet, consetetur sadipscing elitr')
       .end()
   .start();
}); 

The function step() adds a new step. Each step is separate Backbone view instance (DisposableView to be more precise). The following function calls title() and content() both work on that view; end() just returns to the tour (same idea as in jQuery's end()). This allows long definition chains. A more complex example that puts a spotlight on an element:

 
require(['io.ox/core/tk/wizard'], function (Tour) {
   new Tour()
   .step()
       .title('Welcome')
       .content('Lorem ipsum dolor sit amet, consetetur sadipscing elitr')
       .mandatory()
       .end()
   .step()
       .title('Step 2')
       .content('Lorem ipsum dolor sit amet, consetetur sadipscing elitr')
       .spotlight('#io-ox-topbar')
       .pointAt('.launchers-secondary')
       .mandatory()
       .beforeShow(function () {
           // do anything you want to customize the step
           console.log('before show', this);
       })
       .end()
   .start();
});

end()	Go back to parent element, i.e. the Wizard or the Tour.
start()	Start the wizard/tour.
Step
title()	Append content to the popup title. Handed over to jQuery's append; can be String, DOM element, jQuery set, a function.
content()	Append content the popup body. Handed over to jQuery's append; can be String, DOM element, jQuery set, a function.
footer()	Append content to the popup footer. Handed over to jQuery's append; can be String, DOM element, jQuery set, a function.
mandatory()	Makes a step mandatory. The "close" icon gets removed; escape key no longer works.
toggleNext(state)	Enables (true) or disables (false) the "Next" button
toggleBack(state)	Enables (true) or disables (false) the "Back" button
isFirst()	Returns true if the current step is the first one
isLast()	Returns true if the current step is the last one
pointAt(selector)	Affects the dialogs location (alignment happens automatically).
spotlight(selector)	Sets a spotlight on a given element
modal([state])	Shows a darker backdrop. Default is true.
waitFor(selector)	The step waits for a certain element to exist before showing the popup.
navigateTo(id, [options])	The step launches given app (id) before showing the popup. "options" are optional; handed over to ox.launch().
scrollIntoView(selector)	This element will be scrolled into view before the popup is shown
beforeShow(callback)	Registers for the "before:show" event using once(). The callback's context is the step, i.e. "this" is a backbone view.

Using the registry

A tour only works once, i.e. its steps get disposed once the tour stops. This is intended behavior in order to avoid side-effects and memory leaks. If you want to run a tour twice you have to redefine it. The registry simplifies that:

 
require(['io.ox/core/tk/wizard'], function (Tour) {

    // you can store any data you want; only 'id' is mandatory
    Tour.registry.add({ id: 'test', title: 'Test', type: 'tour' }, function () {

        new Tour()
        .step()
            .title('Welcome')
            .content('Lorem ipsum dolor sit amet, consetetur sadipscing elitr.')
            .spotlight('.classic-toolbar')
            .end()
        .start();
    });

    // run a tour
    Tour.registry.run('test');
});

The registry also helps at listing existing tours:

 
require(['io.ox/core/tk/wizard'], function (Tour) {
    // get all items
    console.log(Tour.registry.list());
    // just get type=tour
    console.log(Tour.registry.list('tour'));
    // which is a shortcut for
    console.log(Tour.registry.collection.where({ type: 'tour' }));
});
