VUE3 Getting Started Example: Making a Simple Video Player
With the continuous emergence of new generation front-end frameworks, VUE3 is highly loved as a fast, flexible, and easy-to-use front-end framework. Next, let's learn the basics of VUE3 and make a simple video player.
1. Install VUE3
First, we need to install VUE3 locally. Open the command line tool and execute the following command:
npm install vue@next
Then, create a new HTML file and introduce VUE3:
<!doctype html>
<html>
<head>
<title>VUE3视频播放器</title>
</head>
<body>
<div id="app">
<video src="" controls></video>
</div>
<script type="module">
import {createApp} from 'vue';
const app = createApp({
data() {
return {
videoSrc: ''
};
},
methods: {
playVideo() {
this.$refs.video.play();
},
pauseVideo() {
this.$refs.video.pause();
}
}
});
app.mount('#app');
</script>
</body>
</html>This code first introduces VUE3 and creates an app named "app" root node. Among them,
- videoSrc is used to store the path of the video
- The playVideo method is used to play the video
- ThepauseVideo method is used to pause the video
2. Binding data
In this example, we will use v-model to bind the value of the `` tag to videoSrc so that we can change the video path by setting the value of the input box. We can also use v-bind to bind the src attribute of the video tag to videoSrc:
<div>
<input v-model="videoSrc" type="text" placeholder="在这里输入视频地址" />
<br />
<br />
<video ref="video" v-bind:src="videoSrc" controls></video>
</div>Here, we bind the data to an input box and bind the video path to the video tag.
3. Add Control Buttons
Next, we add two event listeners that allow us to add control buttons on the page - one for playing the video and one for pausing the video. .
<div>
<input v-model="videoSrc" type="text" placeholder="在这里输入视频地址" />
<br />
<br />
<video ref="video" v-bind:src="videoSrc" controls></video>
<br />
<br />
<button v-on:click="playVideo()">播放</button>
<button v-on:click="pauseVideo()">暂停</button>
</div>4. Summary
Now, we have built a simple VUE3 video player. Through this simple example, you have learned about the basic data binding of VUE3 and how to bind and control the video tag. From this foundation, you can delve deeper into VUE3 and apply it to richer applications.
The emergence of VUE3 allows front-end engineers to get rid of some tedious operations and processes, greatly improving development efficiency. Hope this article is helpful to you.

What method is used to convert strings into objects in Vue.js?
Apr 07, 2025 pm 09:39 PM
When converting strings to objects in Vue.js, JSON.parse() is preferred for standard JSON strings. For non-standard JSON strings, the string can be processed by using regular expressions and reduce methods according to the format or decoded URL-encoded. Select the appropriate method according to the string format and pay attention to security and encoding issues to avoid bugs.

What does the vue component pass value mean?
Apr 07, 2025 pm 11:51 PM
Vue component passing values is a mechanism for passing data and information between components. It can be implemented through properties (props) or events: Props: Declare the data to be received in the component and pass the data in the parent component. Events: Use the $emit method to trigger an event and listen to it in the parent component using the v-on directive.
What does it mean to lazy load vue?
Apr 07, 2025 pm 11:54 PM
In Vue.js, lazy loading allows components or resources to be loaded dynamically as needed, reducing initial page loading time and improving performance. The specific implementation method includes using <keep-alive> and <component is> components. It should be noted that lazy loading can cause FOUC (splash screen) issues and should be used only for components that need lazy loading to avoid unnecessary performance overhead.
