How to use Vue to implement floating button effects

Introduction:
Vue.js is a popular JavaScript framework that simplifies the development process of web applications , and provides rich functions and flexible architecture. In this article, I will show you how to use Vue.js to implement a floating button effect and provide detailed code examples.

Steps:

1. First, introduce the Vue.js library into your HTML file. You can do this in the following way:

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

2. Next, create a Vue instance and define a data property to store the button's state. In this example, we will use a boolean value to indicate whether the button was clicked.

new Vue({
  el: '#app',
  data: {
    isClicked: false
  }
});

3. In the HTML file, create a button element and use the v-bind directive to bind the button's style. When the button is clicked, we update the isClicked value in the data attribute and change the button's style through conditional judgment.

<div id="app">
  <button
    v-bind:class="{ 'clicked': isClicked }"
    v-on:click="isClicked = !isClicked"
  >
    悬浮按钮
  </button>
</div>

4. In the CSS file, define the default style of the button and the style when clicked.

button {
  position: fixed;
  bottom: 20px;
  right: 20px;
  background-color: #4CAF50;
  border: none;
  color: white;
  padding: 15px;
  border-radius: 50%;
  font-size: 24px;
  cursor: pointer;
  box-shadow: 0 2px 5px rgba(0, 0, 0, 0.25);
  transition: background-color 0.3s;
}

button.clicked {
  background-color: #f44336;
}

5. Finally, you can preview the effect in your browser, and when you click on the floating button, its background color will change.

  



  

    
      悬浮按钮
    
  

  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
  <script>
    new Vue({
      el: '#app',
      data: {
        isClicked: false
      }
    });
  </script>
