How to implement the trajectory and motion path of images in Vue?

With the development of the Internet, dynamic effects are becoming more and more important in website design. In JavaScript frameworks like Vue.js, we can use animation libraries to achieve various attractive dynamic effects. This article will introduce how to use Vue.js and animation library to realize the trajectory and motion path of pictures.

First, we need to install Vue.js and animation library in the project. Use the following command in the command line:

npm install vue
npm install animate.css

After the installation is complete, we can use the class name of the animation library in the Vue component to achieve animation effects. Introduce the animation library into the <style></style> tag of this component:

<style>
@import '~animate.css';
</style>

Next, we need to create a data array containing the image path and motion path. For example:

data() {
  return {
    images: [
      {
        src: 'path/to/image1.jpg',
        path: 'path1'
      },
      {
        src: 'path/to/image2.jpg',
        path: 'path2'
      },
      // ...
    ]
  };
}

Each object in this data array contains the path and motion path of the image.

Then, we can loop through this data array in the template of the Vue component and set animation effects for each picture. At the same time, we need to set different delay times for each picture to create a continuous trajectory motion effect. For example:

<template>
  <div>
    <div v-for="(image, index) in images" :key="index" :class="'animated ' + image.path" :style="{animationDelay: index * 0.5 + 's'}">
      <img src="/static/imghwm/default1.png"  data-src="image.src"  class="lazy"  : alt="Image" />
    </div>
  </div>
</template>

In this template, we use the v-for directive to loop through the images array and animate each object. Through the :class directive, we bind the class name of the animation library to the motion path in the picture object. Since each image requires a different delay time, we use the :style directive to set a different delay time for each object.

Finally, we can define the style of each motion path in the <style></style> tag of the Vue component. For example:

<style>
.path1 {
  animation-name: path1;
}

.path2 {
  animation-name: path2;
}

/* 定义运动路径动画 */
@keyframes path1 {
  0% { transform: translate(0, 0); }
  100% { transform: translate(200px, 200px); }
}

@keyframes path2 {
  0% { transform: translate(0, 0); }
  100% { transform: translate(-200px, 200px); }
}
</style>

In this style, we define two different motion path animations: path1 and path2. Each animation starts from the original position and uses transform to realize the translation movement of the picture. You can customize these motion path animations as needed.

Through the above steps, we have completed the process of implementing image trajectory and motion path in Vue.js. In this way, when the page loads, each image will animate according to the specified motion path. By adjusting the image path and motion path in the data array, we can also create more different image trajectory effects.

I hope this article can help you understand how to use Vue.js and animation library to realize the trajectory and motion path of images. I wish you use Vue.js to develop more attractive websites!
