Happy Coding

Add external script in head tag.
First for vue, and second for axios ajax.

<head>

    <script src="https://cdn.jsdelivr.net/npm/vue"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/axios/0.19.0/axios.js"></script>

</head>

In body, add div tag with id="myApp" for virtual DOM Vue

    <div id="myApp" >        

        <!-- v-on:submit.prevent -->
        <form method="post" action="process.php" @submit="submit" ref="formHTML" >

            Firstname: <input type="text" name="firstname" v-model="form.firstname" />
            <br />

            Lastname: <input type="text" name="lastname" v-model="form.lastname" />
            <br />

            Description: <textarea name="description" v-model="form.description" rows="10" cols="50" ></textarea>
            <br />

            Programming Languages (multiple): (hold ctrl + click item)
            <select name="languages[]" v-model="form.languages" multiple >
                <option value="c" >C</option>
                <option value="c++" >C++</option>
                <option value="java" >Java</option>
                <option value="javascript" >Javascript</option>
                <option value="php" >PHP</option>
            </select>
            <br />

            <hr />

            <input type="submit" value="Submit" />

        </form>

Script Vue

    <script>

        let vm = new Vue({

            el: "#myApp",

            data: {
                form: {},
                result: {}
            },

            methods: {

                submit: async function (event) {

                    event.preventDefault();


                    var formHTML = event.target; // this.$refs.formHTML

                    console.log( formHTML ); // formHTML element


                    // https://developer.mozilla.org/en-US/docs/Web/API/FormData/Using_FormData_Objects
                    var formData = new FormData( formHTML );

                    console.log( formData );


                    // https://github.com/axios/axios

                    /* AJAX request */
                    this.ajax( formHTML, formData ); // ajax( form, data, destination = null )

                },

                ajax: async function ( form, data, destination = null ) {

                    await axios( {

                        method: form.method,
                        url: form.action,

                        data: data,

                        config: {
                            headers: { "Content-Type": "multipart/form-data" }
                        }

                    } )

                    /* handle success */
                    .then( result => {

                        this.result = result.data;

                        console.log(result);
                        console.log(result.data);

                    } )

                    /* handle error */
                    .catch( error => {

                        console.error(error)

                    } );

                }

            }
