Submitting a form in Vue.js

To submit a form in Vue.js, you can use the following steps:

1. Bind the form elements to data properties in your Vue component using the v-model directive.

2. Add an event listener to the form's submit button.

3. In the event listener, prevent the default form submission behavior.

4. Submit the form data to your server using a library such as Axios.

5. Update your data properties based on the response from the server.

Example:

HTML

<template>
  <form @submit="onSubmit">
    <input type="text" v-model="name">
    <input type="email" v-model="email">
    <button type="submit">Submit</button>
  </form>
</template>

<script>
import axios from "axios";

export default {
  data() {
    return {
      name: "",
      email: "",
    };
  },
  methods: {
    onSubmit(event) {
      // Prevent the default form submission behavior.
      event.preventDefault();

      // Submit the form data to your server.
      axios.post("/submit", {
        name: this.name,
        email: this.email,
      }).then(() => {
        // Handle the successful form submission.
      }).catch(() => {
        // Handle the failed form submission.
      });
    },
  },
};
</script>
