introduction

Vue.js is a popular JavaScript framework that has now reached version 3.0. But Vue 2.0 has become the framework of choice for modern web development through its flexibility, efficiency, and intuitiveness. This article will introduce the characteristics and advantages of Vue 2.0, and provide a case of using Vue in HTML at the beginning and how to import Vue, and finally make a summary.

1. Features and advantages of Vue 2.0

Vue 2.0 has many exciting features and advantages. First of all, it adopts the idea of component development, so that developers can divide complex web applications into multiple independent and reusable components. This modular approach to development makes the code easier to understand and maintain.

Secondly, Vue 2.0 has responsive data binding capabilities, that is, when the data changes, the page will automatically update to reflect these changes. This simple yet powerful data binding mechanism enables developers to easily manage and control the state of the application. In addition, Vue 2.0 also provides a rich ecosystem of instructions and plug-ins, as well as an easy-to-use template syntax, enabling developers to build interactive and dynamic user interfaces more quickly.

2. Primary use case of Vue in HTML

Below is a simple HTML example using Vue 2.0. First, we need to import Vue's JavaScript file in the HTML file, which can be achieved in the following ways:

Create a new html file

Write the <script> tag code in the body

In Vue 2.0, we can import Vue directly by importing Vue source code files, or use CDN to import Vue:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.js"></script>

Suppose we want to display a counter on the page, and the user can click a button to increase the value of the counter. It can be done by following these steps:

Define a container element in HTML, along with an element for displaying the counter value and a button

<div id="app">
  <p>计数器的值：{
     
     { count }}</p>
  <button @click="increment">增加</button>
</div>

Create a Vue instance in JavaScript, and define the required data and methods in `data` and `methods`

<script>
  new Vue({
    el: '#app',
    data: {
      count: 0
    },
    methods: {
      increment() {
        this.count++;
      }
    }
  });
</script>

I've ordered it ten times. . .
Through the above code, we create a Vue instance and bind it to appthe element with id. countThat is, the initial value of the counter we defined, which is bound to <p>the tags in HTML through the double curly braces syntax. incrementmethod is used to increment the value of the counter and will be triggered when the user clicks the button.

Summarize

Vue 2.0 is a feature-rich and easy-to-use front-end framework. Through its component-based development, responsive data binding and other features, it can help developers build modern web applications more efficiently.

This article introduces the features and advantages of Vue 2.0, and provides a simple HTML case to demonstrate the basic use of Vue. At the same time, it also introduces the import method of Vue. I hope this blog can help you understand Vue. I will continue to update more content after I study in depth.
