provides configuration for navigating steps by clicking headers
provides configuration for allowing navigating through steps with unvalidated form elements

Demo

The following demo contains examples for listening to the 'msf:viewChanged' event to update a progress bar as well as defined header step classes to distinguish the current and completed steps and click navigation. View a jsfiddle here

Setup

The multi-step-form-js package requires: 1. use of jQuery and jQuery Validation 2. an .msf-content html element with 1 to N .msf-view html elements and uses optional: 1. jQuery Unobtrusive Validation 2. an .msf-header element with N required .msf-step elements 3. an .msf-navigation element with .msf-nav-button buttons; if buttons are not defined they will be generated

Example Html element with multi-step-form (msf) classes. As progress is made through each step the 'msf-step-active' and 'msf-step-complete' classes will be added to the element of 'msf-step' class adn the 'msf:viewChanged' event is triggered.

Initialize

Requires jQuery and jQuery Validation

<script src=".../path/to/jquery/jquery.min.js"></script>
<script src=".../path/to/jquery/validation/jquery.validate.min.js"></script>

can optionally use jQuery Unobtrusive Validation

<script src=".../path/to/jquery/unobtrusive/validation/jquery.validate.unobtrusive.min.js"></script>

include mulit-step-form.js

<script src="../path/to/multi-step-form-js/multi-step-form.js"></script>

Example Multi-Step-Form-Js initialization with options activeIndex - index of step to initially display, default : 0 allowClickNavigation - allows ability to click steps in header to advance form, default : false allowUnvalidatedStep - allows ability to advance in form without passing validation, default : false hideBackButton - boolean value indicating if back button should be visible after the first step, default : false validate - jQuery Validation options object, default : {}


<script type="text/javascript">
    $(".msf:first").multiStepForm({
        activeIndex : 0,
        allowClickNavigation : true,    
        allowUnvalidatedStep : false,    
        hideBackButton : false,
        validate: {
            rules : {
                name : "required",
                email : {
                    required : true,
                    email : true
                    }
                }
            }
        });
</script>

Example Multi-Step-Form-Js initialization using unobtrusive validation

<script type="text/javascript">
    $(".msf:first").multiStepForm();
</script>

Example jquery event listener to update some progress bar with object parameter containing properties: 'currentIndex', 'previousIndex', and 'totalSteps'

<script type="text/javascript">
    $(document).on("msf:viewChanged", function(event, data){
        var progress = Math.round((data.currentIndex / data.totalSteps)*100);
        $(".progress-bar").css("width", progress + "%").attr('aria-valuenow', progress);
    });

</script>
