Vue.js is a popular JavaScript framework. Its simplicity, efficiency and ease of use have long won the favor of developers. The release of Vue.js 3 further strengthens its position in development.

This article will introduce how to use the Vue.js plug-in to create a time picker in Vue.js 3 to help developers who have not used this framework get started quickly.

First, we need to install Vue.js, which can be installed through the npm command, as shown below:

npm install vue@next

Among them, "@next" means that we will install the latest version of Vue.js, That is Vue.js 3. Once installed, we can use Vue.js to build our time picker.

Vue.js plug-in is a pluggable architecture for Vue.js applications, which can provide us with various functions, including time pickers. We can install and use plugins in Vue.js to extend its functionality.

The following is an example of using the Vue.js plug-in to create a time picker:

First, we need to create a Vue.js component:

<template>
  <div>
    <input type="text" v-model="selectedTime" readonly>
  </div>
</template>

<script>
import { createApp } from 'vue'
import TimePicker from 'vue3-timepicker'

export default {
  components: {
    TimePicker
  },
  data() {
    return {
      selectedTime: ''
    }
  },
  methods: {
    updateSelectedTime(time) {
      this.selectedTime = time
    }
  },
  mounted() {
    const app = createApp(TimePicker, { updateSelectedTime: this.updateSelectedTime })
    app.mount(this.$el)
  }
}
</script>

The above code creates a The Vue.js component uses the TimePicker component in the vue3-timepicker plug-in library. In the component, we use the v-model directive to bind the time selected by the user to the data attribute of the component; at the same time, we also define an updateSelectedTime method in the methods of the component, which is used to update the selectedTime data attribute. Finally, in the component's mounted hook, we use Vue.js's createApp method to create a TimePicker instance and mount it on the DOM element of the current component.

Next, we need to install the vue3-timepicker plug-in. You can use npm to install it, as shown below:

npm install vue3-timepicker

After successful installation, we need to introduce the plug-in into our application, as shown below:

import { createApp } from 'vue'
import TimePicker from 'vue3-timepicker'

const app = createApp({})
app.use(TimePicker)
app.mount('#app')

In the above code, we First, a Vue.js instance was created using the createApp method of Vue.js and mounted on the DOM element "#app". Next, we use the use method of Vue.js to install the vue3-timepicker plug-in. In this way, the TimePicker component can be used in the Vue.js instance.

Finally, we need to introduce the Vue.js library and our components into the html file, as shown below:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Vue.js TimePicker</title>
</head>
<body>
<div id="app">
  <time-picker></time-picker>
</div>

<!-- 引入Vue.js库 -->
<script src="https://unpkg.com/vue@next"></script>

<!-- 引入我们的组件 -->
<script src="time-picker.js"></script>

<!-- 引入vue3-timepicker插件 -->
<script src="vue3-timepicker.js"></script>
</body>
</html>

Finally, we can open the HTML file in a network environment, and that’s it See the time picker application we just created.

The above is a complete process of creating a time picker using Vue.js 3 and Vue.js plug-in library. This process covers the use of Vue.js components and plug-ins, and I hope it will be helpful to beginners.
