With the continuous development of front-end development, there are now more and more types of front-end technology frameworks, such as React, Vue, Angular, etc. Among them, Vue is currently one of the most popular front-end frameworks. It has the advantages of powerful component-based development, convenient template syntax, and good rendering performance. In addition, Vue can also easily introduce jQuery and make better use of jQuery plug-ins and methods to achieve richer effects.

So, how to introduce and use jQuery in Vue? Here is a brief introduction.

Install jQuery
First, we need to install jQuery in the Vue project.
You can enter the following command in the command line window:

npm install jquery --save

After the installation is completed, jQuery will be automatically added to the package.json file.

Introducing jQuery
Introducing jQuery into the Vue project, there are the following two ways:

(1)require method

Can be used in main Use require in .js to introduce jQuery:

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

window.jQuery = require('jquery')
require('bootstrap/dist/js/bootstrap.min')

new Vue({
  render: h => h(App),
}).$mount('#app')

(2) Directly introduce

in index.html. You can also directly introduce jQuery in index.html:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Vue App</title>
  <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://cdn.bootcdn.net/ajax/libs/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</head>
<body>
  <div id="app"></div>
</body>
</html>

Using jQuery
When jQuery is introduced into the Vue project, you can use it happily. Here is an example of using bootstrap's tooltip plug-in:

<template>
  <div class="container">
    <button type="button" class="btn btn-primary mt-5"
        data-toggle="tooltip" title="这是一段提示文本">
      Hover over me
    </button>
  </div>
</template>

<script>
export default {
  mounted() {
    //在mounted方法中初始化tooltip插件
    $('[data-toggle="tooltip"]').tooltip()
  }
}
</script>

It should be noted here that operating DOM elements in a Vue project also requires the use of jQuery's $ symbol. Don't forget to introduce $ when using it.

At this point, we can easily introduce jQuery into the Vue project and use it. After such operations, we can better combine Vue's component development and rich jQuery plug-ins and methods, bringing more possibilities to project development and optimization, making front-end development more convenient.

React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AM

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AM

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

React: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AM

React is a JavaScript library for building user interfaces. Its core idea is to build UI through componentization. 1. Components are the basic unit of React, encapsulating UI logic and styles. 2. Virtual DOM and state management are the key to component work, and state is updated through setState. 3. The life cycle includes three stages: mount, update and uninstall. The performance can be optimized using reasonably. 4. Use useState and ContextAPI to manage state, improve component reusability and global state management. 5. Common errors include improper status updates and performance issues, which can be debugged through ReactDevTools. 6. Performance optimization suggestions include using memo, avoiding unnecessary re-rendering, and using us

Using React with HTML: Rendering Components and DataApr 19, 2025 am 12:19 AM

Using HTML to render components and data in React can be achieved through the following steps: Using JSX syntax: React uses JSX syntax to embed HTML structures into JavaScript code, and operates the DOM after compilation. Components are combined with HTML: React components pass data through props and dynamically generate HTML content, such as. Data flow management: React's data flow is one-way, passed from the parent component to the child component, ensuring that the data flow is controllable, such as App components passing name to Greeting. Basic usage example: Use map function to render a list, you need to add a key attribute, such as rendering a fruit list. Advanced usage example: Use the useState hook to manage state and implement dynamics

React's Purpose: Building Single-Page Applications (SPAs)Apr 19, 2025 am 12:06 AM

React is the preferred tool for building single-page applications (SPAs) because it provides efficient and flexible ways to build user interfaces. 1) Component development: Split complex UI into independent and reusable parts to improve maintainability and reusability. 2) Virtual DOM: Optimize rendering performance by comparing the differences between virtual DOM and actual DOM. 3) State management: manage data flow through state and attributes to ensure data consistency and predictability.

React: The Power of a JavaScript Library for Web DevelopmentApr 18, 2025 am 12:25 AM

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

React's Ecosystem: Libraries, Tools, and Best PracticesApr 18, 2025 am 12:23 AM

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

React and Frontend Development: A Comprehensive OverviewApr 18, 2025 am 12:23 AM

React is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability
