Vue Js Reset Data Values to Initial: In Vue.js, resetting data values refers to updating the state of a component to its initial values. This is useful when you want to clear or reset the state of a component after certain actions have been taken.

To reset data values in Vue.js, you can define a method that sets the data properties to their initial values, and call that method when needed. Alternatively, you can create a copy of the initial data object and assign it to the component’s data property. This will effectively reset the state of the component to its initial values.

In summary, resetting data values in Vue.js involves updating the state of a component to its initial values, which can be achieved by defining a reset method or by creating a copy of the initial data object.

What are the different approaches to reset the data values in Vue.js

1. The data function is defined to return an object that contains the title and message properties, as well as a defaultData property that is initially set to null.
2. In the template, the title property is displayed as an h1 heading, the message property is bound to an input element using the v-model directive, and the value of message is displayed in a p element using interpolation.
3. A button is added to the template with a click event that calls the resetData method when clicked.
4. The resetData method is defined to create a deep copy of the original data object using JSON.parse and JSON.stringify, and then assigns the copy to this.$data using Object.assign.
5. When the button is clicked, the resetData method is called and the component’s data is reset to its initial state.
6. The defaultData property is also displayed in the template, but is not used in the resetData method.

<div id="app">
   <h1>{{ title }}</h1>
   <input type="text" v-model="message" />
   <p>{{ message }}</p>
   <button @click="resetData">Reset Data</button>
    {{defaultData}}
</div>
  <script>
      new Vue({
            el: '#app',
            data() {
                return {
                    title: 'My Component',
                    message: 'Hello, Vue!',
                    defaultData: null
                }
            },
            methods: {
                resetData() {
                    // Create a deep copy of the original data object
                    const originalData = JSON.parse(JSON.stringify(this.$options.data()));
                    Object.assign(this.$data, originalData);
                }
            }
        });
 </script>
