Vue Js Encode Decode Json Object

Vue Js Encode Decode Json Object:Vue.js is a JavaScript framework that allows developers to build interactive and dynamic user interfaces. One of its features is the ability to encode and decode JSON objects. Encoding refers to converting a JavaScript object into a JSON string, while decoding is the process of converting a JSON string into a JavaScript object.

Vue.js provides two methods for encoding and decoding JSON objects: JSON.stringify() and JSON.parse(). JSON.stringify() takes a JavaScript object and returns a JSON string, while JSON.parse() takes a JSON string and returns a JavaScript object

How do you encode a JSON object in Vue.js?

The code JSON.stringify(this.myObject) in Vue.js is used to encode a JavaScript object this.myObject into a JSON string. The resulting JSON string can then be sent over the network or stored in a database.

Here’s how it works:

this.myObject is a JavaScript object that you want to encode as a JSON string.
JSON.stringify() is a built-in JavaScript function that takes a JavaScript object and returns a JSON string representation of that object.
The resulting JSON string is assigned to this.encodedJson, which can be used in your Vue.js application.

Vue Js Encode JSON Object Example

<div id="app">
        <button @click="encodeObject">Encode Object</button>
        <p>Encoded JSON: {{ encodedJson }}</p>
    </div>
    <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    myObject: { name: "John", age: 30, city: "New York" },
                    encodedJson: ""
                };
            },
            methods: {
                encodeObject() {
                    this.encodedJson = JSON.stringify(this.myObject);
                }
            }
        });
    </script>

Output of Vue Js Encode JSON Object

How do you decode a JSON object in Vue.js?

The line of code this.person = JSON.parse(this.jsonString); is used in Vue.js to decode a JSON object and store it in the person data property.

Here’s how it works:

The JSON.parse() method is called with the jsonString variable as its argument. This method takes a JSON string and parses it into a JavaScript object.
The resulting JavaScript object is then assigned to the person data property using the = assignment operator. This means that the person property now holds the decoded JSON object

Vue Js Decode JSON Object Example

  <div id="app">
        <p>JSON string: {{ jsonString }}</p>
        <button @click="decodeJson">Decode</button>
        <p v-if="person">Name: {{ person.name }}, Age: {{ person.age }}</p>
    </div>
    <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    jsonString: '{"name": "John", "age": 30}',
                    person: null
                };
            },
            methods: {
                decodeJson() {
                    this.person = JSON.parse(this.jsonString);
                }
            }
        });
