Function Native Code in Vue Js

Introduction

Vue Js is a popular JavaScript framework used for building interactive user interfaces. It is a progressive framework that supports many advanced features such as reactivity, components, and routing. One of the features that make Vue Js stand out is its ability to integrate with native JavaScript code. In this article, we will discuss how to use native JavaScript code in Vue Js using the function native code feature.

What is Function Native Code in Vue Js?

Function Native Code is a feature in Vue Js that allows you to write and use native JavaScript functions in your Vue components. This feature is useful when you need to manipulate the DOM or perform some complex operations that are not easily achievable using Vue Js directives.

How to Use Function Native Code in Vue Js?

To use Function Native Code in Vue Js, you need to create a method in your Vue component and then call the native JavaScript function inside it. Here is an example:

      <template>
      <div>
      <button @click="showAlert">Show Alert</button>
      </div>
      </template>

      <script>
      export default {
          name: 'MyComponent',
          methods: {
              showAlert() {
                  alert('Hello World!');
              }
          }
      }
      </script>
  

In the above example, we have created a method named showAlert that calls the native JavaScript alert function when the button is clicked. You can also pass arguments to the native JavaScript function by passing them as parameters to the method.

Limitations of Function Native Code in Vue Js

Although Function Native Code in Vue Js is a powerful feature, it comes with some limitations. One of the main limitations is that it does not work well with Vue’s reactivity system. This means that if you manipulate the DOM using native JavaScript code, you may not see the changes reflected in the Vue component. To overcome this limitation, you need to use Vue’s built-in directives or reactive system to manipulate the DOM.

Advantages of Using Function Native Code in Vue Js

Despite the limitations, Function Native Code in Vue Js has many advantages. Some of them are:

• Allows you to use existing JavaScript libraries or functions in your Vue components
• Enables you to perform complex operations that are not easily achievable using Vue Js directives
• Provides more flexibility in terms of how you structure your code

Conclusion

Function Native Code in Vue Js is a powerful feature that allows you to use native JavaScript code in your Vue components. It provides more flexibility and enables you to perform complex operations that are not easily achievable using Vue Js directives. However, it comes with some limitations, and you need to be careful when using it to avoid breaking Vue’s reactivity system.
