humni/multi-step-form

Requires jQuery

This multi-step-form Animator handles the and submits multi-step forms. Each step is treated as its own form and is submitted and handled with event handlers. The goal is to create a robust multi-step form handler.

Documentation

Simple Example

Include the multi-step-form.min.js

multiStepForm.init('.multi-step-form');  
multiStepForm.addNextBtns('.multi-step-form-next');  
multiStepForm.addPrevBtns('.multi-step-form-prev');

Custom Submit Handler Example

multiStepForm.init('#steps-container');
multiStepForm.addNextBtns('.multi-step-form-next');

submitHandler = function (){
    var form = multiStepForm.getCurrentStep();

    //submit the form
    $.ajax({
        type: 'post',
        url: $(form).attr('action'),
        data: $(form).serialize(),
        success: function () {
            console.log('Success!');
        },
        error: function () {
            console.log('Error!');
        }
    });

    //This prevents any other submit handlers (including the default) from running
    return false;
}

//finally add the handler to the multiStepForm
multiStepForm.addHandler('submit', submitHandler);

Methods

init(selector)
Sets up the multi-step-form with the selector for the container of the multi-step-form.

addNextBtns(selector)
Binds the nextStep to the click event of the specified selector

addPrevBtns(selector)
Binds the prevStep to the click event of the specified selector

addHandler(event, function) : boolean
This adds an event handler to one of the events. Use the eventName in the event parameter, and the function parameter must be a function. If a bound event handler returns false, the event will no longer bubble through the bound handlers. Handlers executed in order of which they are bound, with the default handler executing last.

This will return true if the hander was bound successfully.

next()
This will go to the next step

prev()
This will go to the previous step

goToStep(step, submit = false)
This will go to the specified step, and will submit the current step if submit is set to true.

getCurrentStep() : jQueryObject
Will return the current step of the multi-step form.

Events

nextStep
Called when going to the next step. stepId is the new step number

prevStep
Called when going to the previous step. stepId is the new step number

submit
Called to submit the forms for the current step. The default handler will use synchronous ajax to post the form to the forms action property.
