How to use Vue to implement QQ-like chat bubble effects
In today's social era, the chat function has become one of the core functions of mobile applications and web applications. One of the most common elements in the chat interface is the chat bubble, which can clearly distinguish the sender's and receiver's messages, effectively improving the readability of the message. This article will introduce how to use Vue to implement QQ-like chat bubble effects and provide specific code examples.
First, we need to create a Vue component to represent the chat bubble. A component contains two main parts: sent messages and received messages. We can pass these message data through props and set different styles according to the message type. The following is a simple sample code for a chat bubble component:
<template> <div :class="{'message-bubble': true, 'receiver': isReceiver, 'sender': !isReceiver}"> <div class="message-content">{{ message }}</div> </div> </template> <script> export default { props: { message: { type: String, required: true }, isReceiver: { type: Boolean, required: true } } } </script> <style scoped> .message-bubble { padding: 10px; border-radius: 10px; margin-bottom: 10px; } .receiver { background-color: #e6e6e6; color: black; align-self: flex-start; } .sender { background-color: #007bff; color: white; align-self: flex-end; } .message-content { word-wrap: break-word; } </style>
In the above code, we define a CSS class named message-bubble
to style the bubble. Depending on whether it is the receiver or the sender, we set different background colors and text colors respectively.
Next, we need to use the chat bubble component in the parent component. The parent component can loop through the message list and pass the message and sender/receiver information to the child component through the v-for
directive. The following is a simple parent component sample code:
<template> <div class="chat-container"> <chat-bubble v-for="message in messages" :message="message.text" :is-receiver="message.receiver" :key="message.id" /> </div> </template> <script> import ChatBubble from './ChatBubble.vue'; export default { components: { ChatBubble }, data() { return { messages: [ { id: 1, text: 'Hello', receiver: true }, { id: 2, text: 'Hi', receiver: false }, { id: 3, text: 'How are you?', receiver: true }, { id: 4, text: "I'm good, thanks!", receiver: false } ] }; } } </script> <style scoped> .chat-container { display: flex; flex-direction: column; } </style>
In the above code, we introduce the chat bubble component ChatBubble
and traverse it in the v-for
directive Message list to create chat bubbles. We have defined some sample messages in the array messages
, including the sender and receiver information.
Finally, we need to register the parent component to the Vue instance in the entry file and mount it into the HTML document. The following is a simple entry file sample code:
import Vue from 'vue' import App from './App.vue' new Vue({ render: h => h(App) }).$mount('#app');
By running the above code, we can see the effect of a QQ-like chat interface in the browser, including chat bubbles for the sender and receiver. .
To sum up, this article introduces how to use Vue to implement QQ-like chat bubble effects. By creating a chat bubble component, we can easily display the sender and receiver's messages in the chat interface and set different styles for them. This QQ-like chat bubble effect can help us better display chat content and improve user experience. I hope this article can provide some reference and help for beginners.

Vue.js and React each have their own advantages and disadvantages. When choosing, you need to comprehensively consider team skills, project size and performance requirements. 1) Vue.js is suitable for fast development and small projects, with a low learning curve, but deep nested objects can cause performance problems. 2) React is suitable for large and complex applications, with a rich ecosystem, but frequent updates may lead to performance bottlenecks.

Vue.js is suitable for small to medium-sized projects, while React is suitable for large projects and complex application scenarios. 1) Vue.js is easy to use and is suitable for rapid prototyping and small applications. 2) React has more advantages in handling complex state management and performance optimization, and is suitable for large projects.

Vue.js and React each have their own advantages: Vue.js is suitable for small applications and rapid development, while React is suitable for large applications and complex state management. 1.Vue.js realizes automatic update through a responsive system, suitable for small applications. 2.React uses virtual DOM and diff algorithms, which are suitable for large and complex applications. When selecting a framework, you need to consider project requirements and team technology stack.

Vue.js and React each have their own advantages, and the choice should be based on project requirements and team technology stack. 1. Vue.js is community-friendly, providing rich learning resources, and the ecosystem includes official tools such as VueRouter, which are supported by the official team and the community. 2. The React community is biased towards enterprise applications, with a strong ecosystem, and supports provided by Facebook and its community, and has frequent updates.

Netflix uses React to enhance user experience. 1) React's componentized features help Netflix split complex UI into manageable modules. 2) Virtual DOM optimizes UI updates and improves performance. 3) Combining Redux and GraphQL, Netflix efficiently manages application status and data flow.

Vue.js is a front-end framework, and the back-end framework is used to handle server-side logic. 1) Vue.js focuses on building user interfaces and simplifies development through componentized and responsive data binding. 2) Back-end frameworks such as Express and Django handle HTTP requests, database operations and business logic, and run on the server.

Vue.js is closely integrated with the front-end technology stack to improve development efficiency and user experience. 1) Construction tools: Integrate with Webpack and Rollup to achieve modular development. 2) State management: Integrate with Vuex to manage complex application status. 3) Routing: Integrate with VueRouter to realize single-page application routing. 4) CSS preprocessor: supports Sass and Less to improve style development efficiency.

Netflix chose React to build its user interface because React's component design and virtual DOM mechanism can efficiently handle complex interfaces and frequent updates. 1) Component-based design allows Netflix to break down the interface into manageable widgets, improving development efficiency and code maintainability. 2) The virtual DOM mechanism ensures the smoothness and high performance of the Netflix user interface by minimizing DOM operations.
