Submitting form in Vue.js with ajax

Question

I'm really stuck on how I would work with submitting a form that makes an ajax request using Vue.js and vue-resource then using the response to fill a div.

I do this from project to project with js/jQuery like this:

view in blade

{!! Form::open(['route' => 'formRoute', 'id' => 'searchForm', 'class' => 'form-inline']) !!}
    <div class="form-group">
        <input type="text" name="id" class="form-control" placeholder="id" required="required">
    </div>
    <button type="submit" class="btn btn-default">Search</button>
{!! Form::close() !!}

js/jquery

var $searchForm = $('#searchForm');
var $searchResult = $('#searchResult');

$searchForm.submit(function(e) {
    e.preventDefault() ;

    $.get(
        $searchForm.attr('action'),
        $searchForm.serialize(),
        function(data) {
            $searchResult.html(data['status']);
        }
    );
});

What I've done/tried so far in Vue.js:

view in blade

{!! Form::open(['route' => 'formRoute', 'id' => 'searchForm', 'class' => 'form-inline']) !!}
    <div class="form-group">
        <input type="text" name="id" class="form-control" placeholder="id" required="required">
    </div>
    <button type="submit" class="btn btn-default" v-on="click: search">Search</button>
{!! Form::close() !!}

vue/js

    Vue.http.headers.common['X-CSRF-TOKEN'] = document.querySelector('#token').getAttribute('value');

    new Vue({
        el: '#someId',

        data: {

        },

        methods: {
            search: function(e) {
                e.preventDefault();

                var req = this.$http.get(
                    // ???, // url
                    // ???, // data
                    function (data, status, request) {
                        console.log(data);
                    }
                );
            }
        }
    });

I'm wondering if it's possible to use components when dealing with the response to output the response data to a div?

Just to summarise everything:

1. How do I submit a form using vue js and vue-resource instead of my usual jQuery way?
2. Using a response from ajax, how can I output data into a div preferably using components?

Answer 1

In order to get the value from input you have to use v-model Directive

1. Blade View

<div id="app">
<form v-on="submit: search">
    <div class="form-group">
        <input type="text" v-model="id" class="form-control" placeholder="id" required="required">
    </div>
    
    <input type="submit" class="btn btn-default" value="Search">
</form>
</div>

<script type="text/javascript">

// get route url with blade 
var url = "{{route('formRoute')}}";

Vue.http.headers.common['X-CSRF-TOKEN'] = document.querySelector('#token').getAttribute('value');


var app = new Vue({
    el: '#app',
    data: {
        id: '',
        response: null
    },
    methods: {
        search: function(event) {
            event.preventDefault();
            
            var payload = {id: this.id};

            // send get request
            this.$http.get(url, payload, function (data, status, request) {

            // set data on vm
            this.response = data;

            }).error(function (data, status, request) {
                // handle error
            });
        }
    }
});
</script>

If you want to pass data to component the use 'props' see docs for more info

http://vuejs.org/guide/components.html#Passing_Data_with_Props

If you want use laravel and vuejs together, then checkout

Answer 2

1. Add v-model="id" on your text input

2. then add it to your data object

   new Vue({
       el: '#someId',
   
       data: {
           id: ''
       },
   
       methods: {
           search: function(e) {
               e.preventDefault();
   
               var req = this.$http.get(
                   '/api/search?id=' + this.id,
                   function (data, status, request) {
                       console.log(data);
                   }
               );
           }
       }
   });
   

3. It’s better to remove v-on="click: search" and add v-on="submit: search" on the form tag.

4. You should add method="GET" on your form.
5. Make sure you have #someId in your html markup.

Answer 3

I used this approach and worked like a charm:

event.preventDefault();

let formData = new FormData(event.target);

formData.forEach((key, value) => console.log(value, key));
