How to set literal code in Vue.js

Vue.js is a popular JavaScript framework for building single-page applications. With Vue.js, you can easily create reusable and easy-to-maintain code while handling the DOM in an elegant way and implement responsive and data-driven user interfaces.

This article will introduce how to set text code in Vue.js to create user-interactive web applications.

1. Create a Vue.js project

First, you need to install Vue.js. You can download Vue.js from the Vue.js official website, or install it using npm. Once installed, you can use the Vue CLI to create a new Vue.js project:

npm install -g @vue/cli
vue create my-project

In this example, We will use the Vue CLI to create a new Vue.js project named "my-project".

2. Create a component

In Vue.js, a component is the basic unit for building a single-page application. Each component contains HTML template, CSS stylesheet and JavaScript code. In order to create a Vue.js component, we need to create a Vue.js Single File Component (SFC).

In Vue.js, an SFC is a file with the .vue file extension that contains a complete component, including its HTML, CSS and JavaScript code.

For example, here is a simple Vue.js SFC:

<template>
  <div>
    <h1>{{ message }}</h1>
    <button @click="changeMessage">Change Message</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: "Hello, Vue.js!"
    };
  },
  methods: {
    changeMessage() {
      this.message = "Vue.js is Awesome!";
    }
  }
};
</script>

<style>
h1 {
  color: red;
}
button {
  background-color: blue;
  color: white;
  padding: 10px;
}
</style>

In this example, we create a component named "my-component". The HTML code in the component uses the template syntax of Vue.js to bind the component's data attribute "message" to the

element in the page. In the component, we also define a method called "changeMessage" that changes from "Hello, Vue.js!" to "Vue.js is Awesome!" when the "Change Message" button is clicked.

The component also contains a section called "style", which is used to define the CSS style of the component.

3. Register Component

To use a component, you need to register the component in your Vue.js application. To do this, import your Vue.js component in Vue.js Components and then register it in your Vue.js instance using Vue.js's global component registrar.

For example, here is how to register "my-component" in a simple Vue.js instance:

import Vue from "vue";
import MyComponent from "./MyComponent.vue";

Vue.component("my-component", MyComponent);

new Vue({
  el: "#app"
});

In this example, we first imported "MyComponent". We then register the "my-component" component into the Vue.js application using Vue.js's global component register. Finally, we create a new Vue.js instance and bind it to the DOM element with the ID "app".

4. Using Components

Finally, to use a Vue.js component, you can include it in the template of your Vue.js instance:

<div id="app">
  <my-component></my-component>
</div>

In this example, we include the "my-component" component in the template of the Vue.js instance using the Vue.js component name "my-component". When you load your Vue.js application in your browser, you will see the message in the component along with a button that allows you to change the message.

Summary

By following the steps above, you can set up literal code in Vue.js to create reusable and easy-to-maintain web applications. Including Vue.js components in a Vue.js instance template is a simple and powerful way to enable users to easily interact and manipulate the code. I hope this article helps you get started with Vue.js quickly and start creating great web applications!
