We covered an example of Declarative Rendering in VueJS. Now let’s see how we can bind a data property to an input element via Vue JS.
Let’s directly dive into the example
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<div id="root">
<input type="text" v-model="message"><br/><br/>
The value of input box is {{message}}<br/><br/>
<button type="submit" onClick="app.message='Namaste'">Change Value</button>
</div>
<!-- development version, includes helpful console warnings -->
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
let app = new Vue({
el: '#root',
data: {
message: "Hello World",
}
});
</script>
</body>
</html>
As you can extending from the previous example. Here we have binded the value of message property to an input box via v-bind attribute. This is two-way binding.
Try changing the value of input box, it will also change the value we display below it. Also to demonstrate that we have a single point to truth. I have created a button which changes the value of message property on clicking the button.
