How to use Vue to implement Alipay-like step counting effects

With the popularity of smartphones, people are paying more and more attention to health and exercise. Alipay is a popular mobile payment application, and the statistics of daily steps have become an important indicator that users pay attention to. In Alipay, the number of steps will gradually change with a simulated animation effect, giving users visual pleasure and a sense of accomplishment. This article will introduce how to use the Vue framework to implement similar step effects and provide specific code examples.

1. Preparation
Before starting to write code, we need to install Vue.js and related dependency packages.

1. Create a new Vue project
   First, make sure Node.js is installed, then open the terminal and execute the following command to create a new Vue project:

vue create step-counter

Select the required features and configurations according to the prompts, and enter the project directory after creation:

cd step-counter

2. Install dependency packages
   In the project directory, execute the following command to install animejsAnimation library and lodash Tool library:

npm install animejs lodash --save

3. Import dependencies
   Import the installed ones in the main.js file in the project Dependency, the code is as follows:

import Vue from 'vue';
import Anime from 'animejs';
import _ from 'lodash';

Vue.prototype.$anime = Anime;
Vue.prototype._ = _;

2. Implement step counting effects
In the Vue project, we can implement Alipay-like step counting effects through custom components and animation effects.

1. Create a step special effect component
   First, create a component file named StepCounter.vue in the project, and implement the step special effect in this component. The code is as follows:

<template>
  <div class="step-counter">
    <div class="number">{{ step }}</div>
  </div>
</template>

<script>
export default {
  name: 'StepCounter',
  data() {
    return {
      step: 0,
    };
  },
  mounted() {
    this.animateNumber(10000); // 设置初始步数和目标步数
  },
  methods: {
    animateNumber(target) {
      this.$anime({
        targets: this,
        step: target,
        round: 1,
        easing: 'linear',
        duration: 1500,
      });
    },
  },
};
</script>

<style scoped>
.step-counter {
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100px;
  height: 100px;
  border-radius: 50%;
  background-color: #f5f5f5;
  font-size: 32px;
  font-weight: bold;
  color: #333;
}

.number {
  position: relative;
}

.number::after {
  content: '步';
  position: absolute;
  left: 100%;
  top: 50%;
  transform: translate(0, -50%);
  margin-left: 6px;
  font-size: 16px;
  font-weight: normal;
  color: #999;
}
</style>

2. Use the step effect component
   In the root component of the Vue project, use the step effect component and pass in the relevant parameters. It can be modified in the App.vue file. The code is as follows:

<template>
  <div id="app">
    <StepCounter />
  </div>
</template>

<script>
import StepCounter from './components/StepCounter.vue';

export default {
  name: 'App',
  components: {
    StepCounter,
  },
};
</script>

<style>
#app {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
}
</style>

3. Running effect
Execute the following command in the terminal to start the Vue development server and preview the number of steps The effect of special effects.

npm run serve

Open the browser and visit http://localhost:8080 to see the imitation Alipay step count effect. The number of steps will gradually change from 0 to 10,000 for 1.5 seconds.

Through the above steps, we successfully used the Vue framework to implement Alipay-like step counting effects. Through Vue's data binding and animation effects, we can easily create beautiful user interfaces and interactive effects. I hope this article can help you understand and use the Vue framework.
