VUE3 Quick Start: Use Vue.js plug-in to create pop-up components

Vue.js is a popular JavaScript framework that provides a component-based way to build user interfaces. The latest Vue.js version 3 is not only optimized in performance, but also adds some new features. In this article, we will quickly introduce how to use Vue.js 3 and plugins to create pop-up components.

1. Create a Vue.js 3 application

Before you start, you need to install Node.js and Vue CLI. You can install these tools using npm:

npm install -g @vue/cli

Next, create a new Vue.js 3 application using the Vue CLI:

vue create my-app
cd my-app
npm run serve

This will create an application called "my-app" new application and start the development server.

2. Install the Vue.js plug-in

To create the pop-up component, we will use a plug-in called Vue.js Modal. To install the plugin, run the following command:

npm install vue-js-modal

Open the src/main.js file and add the following content:

import Vue from 'vue'
import App from './App.vue'
import VModal from 'vue-js-modal'

Vue.config.productionTip = false

Vue.use(VModal)

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

First, we imported the Vue and App components. Next, we imported the Vue.js Modal plugin and executed Vue.use(VModal) to use it as an extension to the Vue.js application.

3. Create a pop-up window component

Now, we can start to create our own pop-up window component. In this case, we will create a simple login form in case the user attempts to perform an action that requires a login.

First, we need to create a new Vue.js component. Create a new file called LoginModal.vue and copy the following code into it:

<template>
  <div id="login-modal">
    <h1>Login</h1>
    <form>
      <div>
        <label for="username">Username:</label>
        <input type="text" id="username" v-model="username" required>
      </div>
      <div>
        <label for="password">Password:</label>
        <input type="password" id="password" v-model="password" required>
      </div>
      <button type="submit">Submit</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      password: ''
    }
  },
  methods: {
    login() {
      // Your login logic goes here
      this.$emit('close')
    }
  }
}
</script>

This component contains a form where users can enter their username and password. When the form is submitted we will call a login method which will contain your login logic. In this example, we just use a placeholder method and emit a close event in it to close the pop-up window.

Now, we will use this LoginModal component in another component to create a popup window.

4. Use the pop-up component

Open the App.vue file and add the following content anywhere in the template tag:

<modal name="login-modal">
  <login-modal @close="$modal.hide('login-modal')"></login-modal>
</modal>
<button @click="$modal.show('login-modal')">Show Login Modal</button>

This code uses Vue. Components and instructions provided by the js Modal plug-in. First, we define a modal window named using the Name property. This modal window contains the LoginModal component we just created. Then, a button is added to the page, and when clicked, the modal window will be displayed.

To close the modal window, we need to issue a close event in the LoginModal component. By using the $modal.hide('login-modal') method, we can listen to it in the parent component and close the modal window.

5. Conclusion

In this article, we learned how to use Vue.js 3 and plug-ins to create pop-up components. The Vue.js Modal plug-in provides us with the ability to create modal windows directly, and we only need to use simple Vue.js components. This way we can quickly and easily create complex user interfaces that allow users to interact with interactive web applications.
