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 npm and running npm install xompass-angular-wizard

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.

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', ['xompass-angular-wizard']);

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

<wizard on-finish="finishedWizard()" on-cancel="cancelledWizard()"> 
    <wz-step wz-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 wz-title="Continuing">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step wz-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.

1. 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
• on-cancel: Here you can put a function to be called when the wizard is cancelled. 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.
• indicators-position: Can use "top" or "bottom" to specify default position for steps.

2. 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. Each step can have the following attributes (we will go into detail on each further below):

• wz-title: A unique title used for identifying each step.
• wz-heading-title A heading title display above step indicators
• canenter
• canexit
• wz-disabled
• description: A description available to use in each step's UI.
• wz-data Data you wish to make available to the steps scope.
• wz-order The order in which the steps should be in. If no order or duplicated order it will add the step to the end.

3. 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: Calls on-cancel if defined, otherwise the default action is to go 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.
• wz-reset: This will reset the wizard meaning bring the user to the first step and reset each step to being incomplete.

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 Dynamic Steps

A step can be conditionally disabled and may change at any time either adding it or removing it from the wizard step flow.

Example

HTML

<wizard on-finish="finishedWizard()" on-cancel="cancelledWizard()"> 
    <wz-step wz-title="Starting" wz-disabled="{{disabled}}">
        <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 wz-title="Continuing">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step wz-title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>

Controller

//this will cause the step to be hidden
$scope.disabled = 'true';

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 function 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 function 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()" on-cancel="cancelledWizard()"> 
    <wz-step wz-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 wz-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 wz-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 wz-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.
• cancel: Goes to the previous step.
• reset: Goes to the first step and resets all steps to incomplete.
• 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.
• currentStepTitle(): This returns a String which is the title of the step you are on.
• currentStepDescription(): This returns a String which is the description of the step you are on.
• currentStep(): This returns an Object which is the current step you are on.
• totalStepCount(): This returns an Number which is the total number of enabled steps.
• getEnabledSteps(): This returns an Array which is the enabled steps.
• setEditMode(boolean): Set the edit mode of the wizard. Setting editMode to true will make ALL steps accessible, setting edit mode to false will make all steps with an index lower than the latest "completed" step accessible.

Events

Angular Wizard emits the following events on the scope and pass an object with the step info and the index as argument:

• wizard:stepChanged: When succeed changing the current step
• wizard:stepChangeFailed: When changing step and either fails canexit of leaving step or canenter of arriving step.

$scope.$on('wizard:stepChanged',function(event, args) {
    console.log(args);
}

Navigation bar

Any changes you wish to make to the navigation bar can be done by overwritting the CSS. Because everyone wants the navigation bar in a different location and in a different style we have provided a default which you can change via your own HTML and CSS. 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)

Color Definitions

All of those colors are variables in the angular-wizard.less. You can easily change them by importing the angular-wizard.less file into your own less file(s) and change the variables. The available variables are:

• @wz-color-default
• @wz-color-done
• @wz-color-current
• @wz-color-editing
