Vue Js Inheritance Call Parent Method

Vue.js is a popular JavaScript framework that offers developers a flexible and efficient way to build interactive web applications. One common requirement in web development is the ability for child components to communicate with their parent components. In this article, we will explore how you can use Vue.js to implement inheritance and call methods defined in a parent component from a child component.

To start, let's create a simple Vue.js setup with a parent component and a child component. In the parent component, define a method that you want to call from the child component. For example, we can create a method named `parentMethod`:

Vue.component('parent-component', {
  template: `
    <div>
      <h2>Parent Component</h2>
      
    </div>
  `,
  methods: {
    parentMethod() {
      console.log('Method called from parent component');
    }
  }
});

Vue.component('child-component', {
  template: `
    <div>
      <h3>Child Component</h3>
      <button>Call Parent Method</button>
    </div>
  `,
  methods: {
    callParentMethod() {
      this.$parent.parentMethod();
    }
  }
});

new Vue({
  el: '#app'
});

In this code snippet, we have a `parent-component` that includes a child component `child-component`. The child component has a button that, when clicked, calls the `callParentMethod` method. This method, in turn, utilizes the `$parent` property to access the parent component and call the `parentMethod`.

Remember to make sure you have Vue.js included in your project. You can include it via a CDN or install it via npm if you prefer.

Now, when you run your application and click the "Call Parent Method" button in the child component, you should see the message "Method called from parent component" logged to the console.

Through this simple example, you can see how Vue.js enables you to establish a communication channel between parent and child components through method inheritance. This feature is powerful as it allows you to create modular and reusable code in your Vue.js applications.

In conclusion, Vue.js provides a convenient way to handle inheritance and method calls between components, making it easier for developers to design interactive and robust web applications. By understanding and leveraging Vue.js' component-based architecture, you can build applications that are both efficient and maintainable. Experiment with these concepts in your Vue.js projects to unlock a whole new level of functionality and organization. Happy coding!
