How To Call A Vue Js Function On Page Load

When you're working with Vue.js, you might come across situations where you need to call a specific function when a page loads. This can be particularly useful for initializing data, fetching information from an API, or setting up certain configurations. In this article, we'll walk you through how to call a Vue.js function on page load.

One way to achieve this is by using the "mounted" lifecycle hook provided by Vue.js. The mounted hook is called after the Vue instance has been mounted to the DOM, making it a perfect place to execute code when the component is ready.

To call a function on page load using the mounted hook, you need to define the function within your Vue component and then call it inside the mounted hook. Here's a simple example to demonstrate this:

<div>
    <h1>Welcome to our Vue.js Page!</h1>
  </div>



export default {
  mounted() {
    this.callFunctionOnPageLoad();
  },
  methods: {
    callFunctionOnPageLoad() {
      console.log("Function called on page load!");
      // Your code logic here
    }
  }
};

In the above code snippet, we have a Vue component with a mounted hook that calls the "callFunctionOnPageLoad" method when the component is mounted. Inside the method, you can perform any necessary actions you want to take when the page loads.

Remember, the mounted hook is specific to Vue components and is not available at the global Vue instance level. So, if you need to call a function on page load for the entire application, you might want to consider using a plugin or a more global approach.

Keep in mind that calling functions on page load should be done thoughtfully to ensure the best user experience. Excessive or resource-intensive operations could impact performance negatively.

Using the mounted hook is just one way to call a function on page load in Vue.js. Depending on your specific needs, you may explore other lifecycle hooks or additional techniques to achieve the desired functionality.

In conclusion, knowing how to call a Vue.js function on page load can be a valuable skill when working on web applications. By utilizing the mounted hook or other suitable methods, you can execute code precisely when needed without any hassle. Experiment with different approaches and see what works best for your particular project. Happy coding!
