Two way data binding in Vue

Sometimes we need to bind the value of a field and we need to change the data on the Vue instance in real time. If we use the standard bind we used in a tutorial of this series before, it would not work. In order to do that, we must use the v-model directive:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Test</title>
</head>
<body>
  <div id="demo">
    {{ realTimeString }}
    <br>
    <input type="text" name="string" v-model="realTimeString">
</div>
<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js"></script>
<script type="text/javascript">


  new Vue({
  el: '#demo',
  data: {
    realTimeString : ""
  }
});

</script>

</body>
</html>
Enter fullscreen mode Exit fullscreen mode

We'll see how the string over the field will change according to what we type in that field.
