Solution

You can use the v-if conditional rendering for disabling the form and showing the message. https://v2.vuejs.org/v2/guide/conditional.html

Just create a variable like savingSuccessful: false and set it to true when your ajax request was successful.

Use it now in your form like

 <form @submit.prevent="submit" v-if="!savingSuccessful">

This means your form will be displayed until your variable is true.

For a success-message you can create something like this:

<div class="success" v-if="savingSuccessful"> 
    {{ this.text }} 
</div>

Your message will be rendered when the variable is true.
