# jQuery.wizard
$( "form" ).wizard( [ options ] );
This plugin turns a standard HTML form into a wizard by breaking it into a
series of well-defined steps. The purpose of these steps is to better group
related inputs, preventing the user from becoming overwhelmed at the size or
complexity of a form and helping them to better understand the structure of
an unfamiliar form.
## Structure
The basic stucture of the wizard revolves around steps and branches, the
latter being optional. A simple, linear form may only require one branch that
contains all of the steps, whereas a complex form may require the use of
several branches, or even nested branches. The number of steps and branches in
a form is thus left entirely to the developer.
## Navigation
The wizard employs an asynchronous
[finite-state machine](http://en.wikipedia.org/wiki/Finite-state_machine) that
determines how to navigate through itself. This is accomplished by defining
states within the wizard, which are attached to steps, along with their
corresponding action. Steps without states attached will perform the default
action of going to the next step in the current branch.
### States
States are attached to steps via the state attribute, as defined by
`options.stateAttribute`. States can refer to the name of a transition
function, the index of a step or the name of the branch.
### Transitions
$( "form" ).wizard({
transitions: {
gender: function( state, action ) {
return state.step.find( "[name=gender]" ).val();
}
}
});
Transitions act as a bridge between one state and another. They can be used
to allow custom logic to determine where to go next and should ultimately
return a step index or branch name in the wizard.
#### Arguments
Transitions are called with the wizard object as the context and these
arguments:
* **state** _Object_
The current state of the wizard.
* **action** _Function_
The action function should be used to pass the result back to the wizard
in the case that your transition function is asynchronous.
## Options
Options is a map of key/value pairs that can be passed into the plugin as the
first argument upon initialization. The default values are shown below:
options: {
animations: {
show: {
options: {
duration: 0
},
properties: {
opacity: "show"
}
},
hide: {
options: {
duration: 0
},
properties: {
opacity: "hide"
}
}
},
backward: ".backward",
branches: ".branch",
disabled: false,
enableSubmit: false,
forward: ".forward",
header: ":header:first",
initialStep: 0,
stateAttribute: "data-state",
stepClasses: {
current: "current",
exclude: "exclude",
stop: "stop",
submit: "submit",
unidirectional: "unidirectional"
},
steps: ".step",
submit: ":submit",
transitions: {},
unidirectional: false,
/* callbacks */
afterBackward: null,
afterDestroy: null,
afterForward: null,
afterSelect: null,
beforeBackward: null,
beforeDestroy: null,
beforeForward: null,
beforeSelect: null,
create: null
}
By default the wizard will start on the first step, show and hide steps
instantly, transition to the next step in the same branch as the current step
if no state attribute is present and allow movement forwards and backwards.
* **animations** _Object_
Used to define custom transition animations on step changes. For more
information, read up on jQuery's [.animate()](http://api.jquery.com/animate)
function.
* **show** _Object_
The options and properties that will be used when showing a step.
* **hide** _Object_
The options and properties that will be used when hiding a step.
* **backward** _String_
A selector string used to indicate which elements to bind the `backward()`
method to. The method will be triggered on click.
* **branches** _String_
A selector string used to indicate which elements are branches within the
wizard.
* **enableSubmit** _Boolean_
Whether or not to enable the submit button on all steps.
* **forward** _String_
A selector string used to indicate which elements to bind the `forward()`
method to. The method will be triggered on click.
* **header** _String_
A selector string used to locate the header of the wizard.
* **initialStep** _String_, _Number_, _Array_
Which step to display after the wizard initializes. Accepts a string
representing a step or branch ID, a number representing a step index,
a jQuery object or DOM element representing a step or branch, or an
array of arguments to be passed to the `select()` method.
* **stateAttribute** _String_
The attribute, applied to steps, that contains the name of a state.
* **stepClasses** _Object_
A map of meaningful step classes. These classes will have an effect on step
behavior such as enabling or disabling navigation or preventing the step
from being included in overall progress.
* **current** _String_
The class to toggle on the currently selected step.
* **exclude** _String_
If this class is present on a step the step will not be included in the
progress estimate. This is useful for steps that might contain
explanitory or introductory text without any inputs.
* **stop** _String_
If this class is present on a step the forward button will be disabled.
* **submit** _String_
If this class is present on a step the submit button will be enabled.
* **unidirectional** _String_
If this class is present on a step the backward button will be
disabled.
* **steps** _String_
A selector string used to indicate which elements are steps within the
wizard.
* **transitions** _Object_
A map of keys representing states and their corresponding action methods.
* **default** _Function_
The default transition to use on steps that contain no state attribute.
* **unidirectional** _Boolean_
Whether or not this wizard should be unidirectional; that is allowing only
forward movement.
## Events
$( "form" )
// Bind on initialization
.wizard({
eventHandler: function( event, state ) { ... }
})
// Bind at any other time
.bind( "wizardeventhandler", function( event, state ) { ... });
Event handlers may be passed in on intialization in the options object, or they
can be bound to the wizard at any time using the format _wizardeventname_
(note that it must be in all lowercase).
* **afterBackward** or _wizardafterbackward_
Triggered after the wizard has completed going backwards.
* **afterDestroy** or _wizardafterdestroy_
Triggered after the wizard has been destroyed.
* **afterForward** or _wizardafterforward_
Triggered after the wizard has completed going forwards.
* **afterSelect** or _wizardafterselect_
Triggered after the wizard has completed selecting a new step.
* **beforeBackward** or _wizardbeforebackward_
Triggered before the wizard attempts to move backwards. Returning false
inside of this method will prevent the move.
* **beforeDestroy** or _wizardbeforedestroy_
Triggered before the wizard is destroyed. Returning false inside of this
method will prevent the destruction of the wizard.
* **beforeForward** or _wizardbeforeforward_
Triggered before the wizard attempts to move forward. Returning false inside
of this method will prevent the move.
* **beforeSelect** or _wizardbeforeselect_
Triggered before the wizard attempts to move in any direction. Returning
false inside of this method will prevent the move.
#### Arguments
Events are called with the wizard element as the context and these arguments:
* **event** _Object_
The [jQuery.Event](http://api.jquery.com/category/events/event-object/)
object.
* **state** _Object_
An object containing either the current state of the wizard (for _after_
events) or the state the wizard will be updating to (for _before_ events).
See the [state](readme.md#state) section for further information.
* [ **update** ] _Function_
This function is available on any of the **before** events to allow
deferred cancellation of events if asynchronous processing is needed.
## Methods
$( "form" ).wizard( "methodName" [, args ] );
The wizard comes with plenty of public methods to help you navigate and get at
any relevent information you may need.
* **backward( [ event, howMany ] )** returns _jQuery_
Step backward through the wizard.
* **event** _Event_
The [jQuery.Event](http://api.jquery.com/category/events/event-object/)
object. Used when the function is called via a trigger or event handler.
* **howMany** _Number_
How many steps to take backwards. Should be a positive integer greater
than zero.
* **branch( [ branch ] )** returns _jQuery_
Returns a branch from the wizard. If no arguments are provided, it will
return the currently active branch.

The ID of a branch in the wizard.
* **branches( [ branch ] )** returns _jQuery_
Returns several branches in the wizard. If no arguments are provided, it
will return all of the branches in the wizard.
* **branch** _String_
The ID of a branch in the wizard. If provided, all of the branches
within the given branch are returned.

Returns all of the activated branches in the wizard. An activated branch
is defined as any branch containing a step that has been visited.
* **destroy()** returns _jQuery_
Completely remove the wizard functionality from the element it was attached
to. This basically reverts the element to the state it was before the
wizard was applied to it.
* **form()** returns _jQuery_
Returns the form associated with the wizard.
* **forward( [ event, howMany ] )** returns _jQuery_
Step forward through the wizard.
* **event** _Event_
The [jQuery.Event](http://api.jquery.com/category/events/event-object/)
object. Used when the function is called via a trigger or event handler.
* **howMany** _Number_
How many steps to take forwards. Should be a positive integer greater
than zero.
* **isValidStep( step )** returns _Boolean_
Returns whether or not a step is valid, or contained within the wizard.
* **step** _String_, _Number_, _jQuery_, _Element_
The step to check for in the wizard. Can be an element ID, step index,
jQuery object or DOM element.
* **isValidStepIndex( stepIndex )** returns _Boolean_
Returns whether or not a step index is valid, or contained within the
wizard.
* **stepIndex** _Number_
An integer representing the index of a step in the wizard.
* **select( [ event, ] step [, branch, relative, history ] )** returns _jQuery_
Selects a step within the wizard.
* **event** _Event_
The [jQuery.Event](http://api.jquery.com/category/events/event-object/)

step by step index relative to a branch. This parameter may be omitted
even if further arguments are needed.
* **relative** _Boolean_
If true, the step argument becomes an integer representing the number
of steps to move forwards or backwards relative to the current step.
This parameter may be omitted even if further arguments are needed.
* **history** _Boolean_, _Array_
Whether or not to track the movements between the current step and the
destination step. If set to false, the history will not be kept. This
means that when hitting the back button on the selected step, the user
will be taken directly back to the step they were on beforehand instead
of visiting any steps in between. You can specify which steps will be
included in the history yourself by passing an array of step indexes
that will override whatever steps the plugin actually takes.
* **state( [ step, branch, stepsTaken ] )** returns _Object_
Returns an object containing the state of the wizard at a certain step, or
null if the step could not be found. If no arguments are provided, returns
the current state of the wizard. See the [state](readme.md#state) section

step by step index relative to a branch. This parameter may be omitted
even if further arguments are needed.
* **stepsTaken** _Array_
An array of step indexes that represent the path taken to get to the
given step from the current step. This should be provided if tracking
history for the generation of an accurate state.

found. If no arguments are provided, it will return the index of the
currently selected step in the wizard.
* **branch** _String_
The ID of the branch that contains the step. Useful of searching for a
step by step index relative to a branch. This parameter may be omitted
even if further arguments are needed.
* **relative** _Boolean_
