v-model is a directive in Vue.js used to create two-way data bindings between form input elements and Vue.js data properties. It implements two-way binding by automatically updating input changes and data changes, unlike other directives such as v-bind and v-on in that it provides two-way binding. v-model can be used with a variety of form input elements, including text input boxes, text areas, check boxes, radio buttons, and drop-down lists.

What is v-model?

v-model is a directive in Vue.js that is used to create two-way data bindings between form input elements and Vue.js data properties.

How v-model works

The v-model directive establishes two-way data binding through the following steps:

  1. Input Changes: When the value of the form input element changes, v-model will automatically update the value of the bound Vue.js data property.
  2. Data changes: When the value of the Vue.js data attribute changes, v-model will automatically update the value of the bound form input element.

How v-model differs from other directives

v-model differs from other data binding directives in Vue.js (such as v-bind Unlike v-on), because it provides two-way data binding, other instructions only support one-way binding.

Usage of v-model

v-model can be used for various form input elements, including:

  • Text input box
  • Text area
  • Check box
  • Radio button
  • Drop-down list

Usage example

<code class="vue"><template>
  <div>
    <input v-model="name">
  </div>
</template>

<script>
export default {
  data() {
    return {
      name: '',
    };
  },
};
</script></code>

In the above example, when the user enters text in the <input> element, the value of the name data attribute will automatically update. Likewise, when the value of the name data attribute changes via Vue.js logic, the text in the <input> element will automatically update.
