vue reset all data to default

Resetting All Data to Default in Vue

// Assuming 'data' is your data object
Object.assign(this.$data, this.$options.data.call(this));

1. Explanation: This code uses Object.assign() to reset the data of the Vue instance to its default values. It accesses the $data property to get the current data object and then uses Object.assign() to merge the default data obtained from $options.data.call(this) into the current data object.

2. Step-by-step:

3. this.$options.data.call(this): This retrieves the default data object defined in the component's options, ensuring that any default data defined in the component is retrieved.
4. Object.assign(this.$data, ...): This uses Object.assign() to merge the default data into the current data object, effectively resetting the data to its default state.

5. The this.$data property refers to the data object of the Vue instance, and this.$options provides access to the options of the Vue component.

6. Note:

7. Ensure that the data option is defined as a function that returns the initial data for the component, rather than an object, to allow for proper resetting of the data.

8. Example: javascript export default { data() { return { message: 'Hello', count: 0 }; }, methods: { resetData() { Object.assign(this.$data, this.$options.data.call(this)); } } };
