Clearing input in vuejs form


What you need is to set this.text to an empty string in your submitForm function:

submitForm(e){    this.todos.push(        {            text: this.text,            completed: false        }    );    this.text = "";    // To prevent the form from submitting    e.preventDefault();}

Remember that binding works both ways: The (input) view can update the (string) model, or the model can update the view.


Assuming that you have a form that is huge or simply you do not want to reset each form field one by one, you can reset all the fields of the form by iterating through the fields one by one

var self = this;Object.keys(this.data.form).forEach(function(key,index) {    self.data.form[key] = '';});

The above will reset all fields of the given this.data.form object to empty string. Let's say there are one or two fields that you selectively want to set to a specific value in that case inside the above block you can easily put a condition based on field name

if(key === "country")    self.data.form[key] = 'Canada';else    self.data.form[key] = ''; 

Or if you want to reset the field based on type and you have boolean and other field types in that case

if(typeof self.data.form[key] === "string")    self.data.form[key] = ''; else if (typeof self.data.form[key] === "boolean")    self.data.form[key] = false;

A basic vuejs template and script sample would look as follow

<template>  <div>    <form @submit.prevent="onSubmit">      <input type="text" class="input" placeholder="User first name" v-model="data.form.firstName">      <input type="text" class="input" placeholder="User last name" v-model="data.form.lastName">      <input type="text" class="input" placeholder="User phone" v-model="data.form.phone">      <input type="submit" class="button is-info" value="Add">      <input type="button" class="button is-warning" @click="resetForm()" value="Reset Form">    </form>  </div></template>

See ow the @submit.prevent="onSubmit" is used in the form element. That would by default, prevent the form submission and call the onSubmit function.

Let's assume we have the following for the above

<script>  export default {    data() {      return {        data: {          form: {            firstName: '',            lastName: '',            phone: ''          }        }      }    },    methods: {      onSubmit: function() {        console.log('Make API request.')        this.resetForm(); //clear form automatically after successful request      },      resetForm() {        console.log('Reseting the form')        var self = this; //you need this because *this* will refer to Object.keys below`        //Iterate through each object field, key is name of the object field`        Object.keys(this.data.form).forEach(function(key,index) {          self.data.form[key] = '';        });      }    }  }</script>

You can call the resetForm from anywhere and it will reset your form fields.


These solutions are good but if you want to go for less work then you can use $refs

<form ref="anyName" @submit="submitForm"></form><script>   methods: {      submitForm(){         // Your form submission         this.$refs.anyName.reset(); // This will clear that form      }   }</script>
