v-model in Vue
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:
- 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.
- 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
<template> <div> <input v-model="name"> </div> </template> <script> export default { data() { return { name: '', }; }, }; </script>
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.
