Usage

import VueMultiStepForm from 'vue-multi-step-form';

Basic Usage

 <vue-multi-step-form
    id="myWizard"
    name="myWizard"
    :step-data="stepData"
    @onComplete="onComplete"
 >
    <template slot="header-row">
       <h2>Wizard Heading</h2>
    </template>
    <template slot="step1">
       <component1 />
    </template>
    <template slot="step2">
       <component2 />
    </template>
    <template slot="step3">
       <component3 />
    </template>
 </vue-multi-step-form>

export dafault{
    data(){
        stepData:[],
    },
    mounted(){
        //optional
        for(let i=0;i<3;i++){
            //these all are default and optional values
            this.stepData.push({
                'step_valid': true,
                'step_skip': false,
                'show_back_button': true,
                'show_next_button': true,
                'last_step': false,
            });
        }
    },
    methods:{
        onComplete(){
            //final step submit
        }
    }
}

If you want to validate step from inside of component use EventBus instead.

Validation

<vue-multi-step-form
    id="myWizard"
    name="myWizard"
    ref="myWizard"
    :step-data="stepData"
    @valdiateStep="valdiateStep"
    @onComplete="onComplete"
 >

if step_valid is false for current step in stepData then VueMultiStepForm will emit validateStep Use your validation package or our VueNiceValidate package to validate current step fields and set step_valid for current_step to true.

methods:{
    valdiateStep(currentStepIndex){
        //validate your current step here
        //if current step is valid set step_valid 
        this.stepData[currentStepIndex].step_valid = true;
        //move to next step 
        this.$refs.myWizard.nextStep();
        //next step will keep emiting validateStep until step_valid is true
    },
}

Post Submit

if action prop is defined then your form will submit through web request else it will emit onComplete event

<vue-multi-step-form
    id="myWizard"
    name="myWizard"
    :action="'/my-post-url'"
    method="POST" 
    :step-data="stepData"
    @valdiateStep="valdiateStep"
 >

Custom Footer

<template
v-slot:footer="props"
>
    <div class="mt-5 m-0-a">
    <div class="row">
        <button
        v-if="!props.isFirstStep"
        type="button"
        class="btn btn-outline-dark fade-in-out mr-1"
        @click="prevClick"
        >
        {{ 'back' }}
        </button>
        <button
        type="button"
        class="btn btn-md btn-primary"
        @click="nextClick"
        >
        {{ props.isLastStep ? (post ? 'Update Post' : 'Create Post') : 'Next' }}
        </button>
    </div>
    </div>
</template>

You can manually go to next step and prev step by using component methods.

methods:{
    nextClick: function (e) {
        this.$refs.multiStep.nextStep();
    },
    prevClick: function (e) {
        this.$refs.multiStep.prevStep();
    },
}
