Angular-Wizard

Angular-wizard is a component that will make it easy for you to create wizards in your app. You can check a running example of the wizard by clicking here

How do I add this to my project?

You can download this by:

Using bower and running bower install angular-wizard
Using npm and running npm install angular-wizard
Downloading it manually by getting the files from the dist folder
Using JsDelivr CDN files:

<!-- Use LATEST folder to always get the latest version-->
<script type="text/javascript" src="http://cdn.jsdelivr.net/angular.wizard/latest/angular-wizard.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.jsdelivr.net/angular.wizard/latest/angular-wizard.min.css">

<!-- Or use TAG number for specific version -->
<script type="text/javascript" src="http://cdn.jsdelivr.net/angular.wizard/0.5.1/angular.wizard.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.jsdelivr.net/angular.wizard/0.5.1/angular-wizard.min.css">

The dist folder contains the following files:

JS files needed for the directives and services
CSS files with default styles for the directive
LESS file with styles for the directive. If you have less in your project, I recommend using the less instead of the CSS since it has variables to configure Wizard colors.

Dependencies

Angular-wizard depends on Angular and Lodash (or Underscore).

Starter Guide

First example

The first thing we need to do is add a dependency to angular-wizard module which is called mgo-angular-wizard.

We can do this simply by doing:

angular.module('your-app', ['mgo-angular-wizard']);

Now, in some HTML for a controller, you can just add a wizard as follows:

<wizard on-finish="finishedWizard()">
    <wz-step title="Starting">
        <h1>This is the first step</h1>
        <p>Here you can use whatever you want. You can use other directives, binding, etc.</p>
        <input type="submit" wz-next value="Continue" />
    </wz-step>
    <wz-step title="Continuing">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>

This will look like the following when you're in the second step:

Let's go step by step to see how this works.

You need to declare a master wizard directive. This wizard directive, has the following options as attributes:

on-finish: Here you can put a function to be called when the wizard is finished. The syntax here is very similar to ng-click
name: The name of the wizard. By default, it's called "Default wizard". It's used for the WizardHandler which we'll explain later.
edit-mode: If set to true, this will set the wizard as edit mode. Edit mode means that all steps have been completed and the user can now navigate to and modify any step. Defaults to false.
hide-indicators: If set to true, the indicators in the bottom of the page showing the current page and allowing navigation for the wizard will be hidden. Defaults to false.
current-step: You need to set here a property from your scope (similar to ng-model) and that property will always have the name of the current step being shown on the screen.
template: Path to a custom template.

Inside the wizard, we can have as many steps as we want. Each step MUST have a title which is going to be used to identify it. Inside each step, we can put whatever we want. Other directives, bindings, controls, forms, etc.
Inside the step, we now see a button which has a wz-next attribute. That means that clicking that button will send the user to the next step of wizard. Similar to wz-next, we have the following attributes:

wz-previous: Goes to the previous step
wz-cancel: Goes back to the first step
wz-finish: Finishes the wizard and calls the on-finish later on. It's important to note that if we're in the last step and we put wz-next it'll be the same as putting wz-finish as the wizard will know we're at the last screen.

All of this attributes can receive an optional function to be called before changing the step. Something like:

<input type="button" wz-next="setMode(mode)" value="Next" />

In this case, the setMode function will be called before going to the next step.

Wizard Step Validation

The wzStep directive has the following options as attributes:

canexit: Here you can reference a function from your controller. If this attribute is listed the funtion must return true in order for the wizard to move to the next step. Promises are supported but must resolve with a thruthy value. If it is ommitted no validation will be required.
canenter: Here you can reference a function from your controller. If this attribute is listed the funtion must return true in order for the wizard to move into this step. Promises are supported but must resolve with a thruthy value. If it is ommitted no validation will be required.

Example

HTML

<wizard on-finish="finishedWizard()">
    <wz-step title="Starting" canexit="exitValidation">
        <h1>This is the first step</h1>
        <p>Here you can use whatever you want. You can use other directives, binding, etc.</p>
        <input type="submit" wz-next value="Continue" />
    </wz-step>
    <wz-step title="Continuing" canenter="enterValidation">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>

Controller

$scope.enterValidation = function(){
    return true;
};

$scope.exitValidation = function(){
    return true;
};
//example using context object
$scope.exitValidation = function(context){
    return context.firstName === "Jacob";
}
//example using promises
$scope.exitValidation = function(){
    var d = $q.defer()
    $timeout(function(){
        return d.resolve(true);
    }, 2000);
    return d.promise;
}

If a step requires information from a previous step to populate itself you can access this information through the context object. The context object is automatically passed in as an argument into your canexit and canenter methods. You can access the context objext from your controller via: WizardHandler.wizard().context

Manipulating the wizard from a service

There are some times where we actually want to manipulate the wizard from the controller instead of from the HTML.

For those cases, we can inject the WizardHandler to our controller.

The main function of this service is the wizard(name) which will let you get the wizard to manipulate it. If you have just one wizard in the screen and you didn't set a name to it, you can just call it as wizard(). Let's see an example:

<wz-step title="Cool step">
    <input type="submit" ng-click="changeLabelAndGoNext()" />
</wz-step>

// In your controller
$scope.changeLabelAndGoNext = function() {
    $scope.model.label = "Hola Gonto";
    WizardHandler.wizard().next();
}

In this case, we're changing a label and moving forward on the steps. The functions available in the wizard() are:

next: Goes to the next step
previous: Goes to the previous step
finish: Finishes the wizard.
goTo(number|title): This goes to the indicated step. It can receive either the number of the step (starting from 0) or the title of the step to go to.
currentStepNumber(): This returns a Number which is the current step number you are on.

Navigation bar

The navigation bar shown below works in the following way:

Completed steps are painted as green
Current step is painted as dark grey
Future step is painted as light grey
Editing step (Modifying a step already completed in the past) is painted as red
You can click in any completed step to go back to that step. You can't click in the current step nor in the future ones unless you've already completed a future step before (for example in EditMode all steps are completed by default)

All of those colors are variables in the angular-wizard.less. You can easily change them by changing the colors in that file

Personalize the navigation bar

By default, the navigation bar can't be easily personalized. The title of the step will be the text displayed. To remedy this, you will have to use your own custom template of navigation bar (default here).

Use the step directive's attribute extra-data to have more control inside your template like this:

In your controller:

$scope.stepData = {
    'icon': 'fa-book',
    'displayName': 'My really cool step',
    'customClass': 'my-custom-class',
    'hide': true
};

In your main view:

<wz-step title="Cool step" extra-data="stepData">
    <input type="submit" ng-click="changeLabelAndGoNext()" />
</wz-step>

In your custom navigation bar template (wizard.html):

...
<li class="{{step.extraData.customClass}}"
    ng-hide="{{step.extraData.hide}}"
    ng-class="{default: !step.completed && ...}"
    ng-repeat="step in steps">

        <a ng-click="goTo(step)">
            <i class="fa {{step.extraData.icon}}"></i>
            {{step.extraData.displayName || step.title || step.wzTitle}}
        </a>
      </li>
...
